How Korean Celebrities Learned English: 6 Real Learning Methods That Actually Work
When you watch Korean celebrities giving interviews in English, speaking confidently on international talk shows, or nailing Hollywood press conferences, it’s easy to think they have some special talent. But the truth? Each one used a different learning method — and you can use the same approaches they did.
Let’s look at how six verified English-fluent Korean celebrities actually learned — and what their methods teach us about what really works for adult English learners.
1. RM (BTS) — Learning English by Rewatching TV Shows
Why you know him: Leader of BTS, global K-pop phenomenon, speaks English in nearly every international interview and gave a speech at the United Nations in fluent English (2018).
His method: RM didn’t attend school abroad. He learned English almost entirely by rewatching the TV show Friends with Korean subtitles, watching the same episodes multiple times. This is the shadowing method without formal instruction — picking up accent, natural speech patterns, and everyday vocabulary from authentic material.
What you see in his English: Native-like pronunciation in most consonant clusters, natural hesitation patterns, solid idiomatic understanding. He speaks conversationally and naturally, not from a script.
Watch him in action: Ellen DeGeneres Show interview — BTS talks about learning English through Friends (pay attention to how he explains his learning method itself — that’s meta-learning in action).
The teaching point: Rewatching the same content multiple times is more effective than watching many different things once. RM’s method proves that volume of repetition beats breadth of exposure for adult learners.
2. Gong Yoo — Self-Study Without Formal Education Abroad
Why you know him: Lead actor in Squid Game (Netflix series), Goblin, Coffee Prince. International film fame.
His method: Gong Yoo never studied abroad. He learned English through self-study and deliberately practised by hosting a radio show teaching conversational English during his mandatory military service. He gave a full BBC interview in English with no translator present.
What you see in his English: Clear pronunciation, grammatically accurate, confident pacing. He doesn’t rush through sentences (common anxiety pattern for Korean speakers). He pauses deliberately to choose words — a sign of real fluency, not memorised script.
Watch him in action: BBC interviews and Louis Vuitton brand ambassador videos — he speaks English in promotional materials without subtitles.
The teaching point: Teaching English to others forced him to refine his own English. If you’re learning, explaining grammar or vocabulary to a friend (or even to yourself aloud) accelerates fluency faster than passive study alone.
3. Choi Siwon (Super Junior) — Immersion During High School
Why you know him: Member of Super Junior (K-pop group with 20+ year career), regular cast member on variety shows, often serves as the group’s English translator.
His method: Studied in America through high school, giving him immersion and peer interaction in English from an adolescent age. He continued using English even after returning to Korea.
What you see in his English: Fluent accent, quick thinking in English, confident switching between Korean and English mid-conversation (code-switching, a sign of real bilingual fluency, not L2 learner hesitation).
Watch him in action: Super Junior variety show clips — he translates for group members and speaks naturally in variety show English games.
The teaching point: Early immersion (pre-university) produces different fluency patterns than adult learning. If you’re an adult learner without immersion access, you need higher-intensity practice (daily speaking, real conversations) to compensate for lack of environmental English.
4. Taecyeon (2PM) — American High School Education
Why you know him: Member of 2PM (K-pop group), actor, variety show regular. Known within the industry for his fluent English and American accent.
His method: Moved to America in middle school and attended high school there, acquiring a genuine American English accent (not just accent-modified Korean English). His peers learned his accent patterns naturally.
What you see in his English: True American accent (rhoticity — pronouncing R’s clearly, vowel shifts like ‘a’ in “cat” vs. “cot”), fast speech rate, idiomatic expressions. He sounds like a native speaker raised in the US, not a learner.
Watch him in action: 2PM interviews with English segments, variety show appearances where he code-switches with English.
The teaching point: Accent is acquired, not learned — it comes from exposure to native speakers during impressionable years. For adult learners, accent improvement requires intensive listening (watching movies, podcasts at native speed) and speaking practice under real-time pressure (speaking partners, not scripted lessons).
5. Lee Seung Gi — Regular Self-Study Commitment
Why you know him: Actor and singer, starred in Alchemy of Souls, A Korean Odyssey. Known for high professionalism.
His method: Regularly studies English as part of his professional development. He’s more fluent in Japanese than English, but maintains English-speaking ability through consistent practice.
What you see in his English: Clear, careful pronunciation, slower pace (sign of real-time processing, not script delivery), accurate grammar. He pauses to think — a sign he’s thinking in Korean and translating, not thinking in English yet.
Watch him in action: Lee Seung Gi variety show English segments, travel shows where he interacts in English.
The teaching point: Consistency matters more than intensity. Lee Seung Gi isn’t super-fluent, but his regular, modest practice keeps him functional. For IELTS learners: 45 minutes daily is better than 4 hours once a week.
6. Choi Woo-shik — Childhood Immersion (Vancouver, Canada)
Why you know him: Actor in Parasite (Oscar-winning film), Abyss, Our Beloved Summer. Hollywood crossover actor.
His method: Family emigrated to Vancouver when he was a child; he grew up speaking English daily. Now identifies as Canadian/Korean (goes by Edward or Eddie in English contexts). His family maintained Korean at home, making him a heritage bilingual speaker.
What you see in his English: Native English accent, natural speech rhythm, zero hesitation in complex sentences. But interestingly, he said on a Korean TV show (Youn’s Stay, 2021) that he now thinks in Korean and translates into English — suggesting that returning to Korea as an adult (and switching his professional context to Korean film/TV) actually shifted his cognitive dominance back toward Korean.
Watch him in action: Parasite interviews, Hollywood press junkets.
The teaching point: Language dominance isn’t fixed — it follows your daily environment. Choi Woo-shik’s story shows that even native-like English fluency can shift if you change your environment. For IELTS learners: your “dominant” language is whatever you use most, so if you want English to stay strong, you need to use it regularly in your life, not just study it.
What These Six Learning Methods Have In Common
- All of them used English in real contexts — not just textbook exercises. RM watched TV shows, Gong Yoo taught a radio show, Choi Siwon translated in real conversations.
- All of them had extended exposure — not crash courses. Even Lee Seung Gi’s “regular study” is ongoing, not a sprint.
- All of them had a reason to learn — a career reason (international fame), an environmental reason (living abroad), or a professional reason (Hollywood films, translation duties). They didn’t learn English “someday, maybe.”
- None of them achieved fluency from grammar books alone. Every single one used real material: TV shows, conversations, professional contexts, immersion. Grammar came after they could communicate.
How to Use These Methods in Your Own Learning
If you’re intermediate (B1–B2): Pick one celebrity’s method and try it for 4 weeks.
- RM’s method: Rewatch one Netflix series (English audio, English subtitles) three times. Write down new phrases each time.
- Gong Yoo’s method: Explain one grammar concept (present perfect, articles, etc.) aloud in English, as if teaching a friend. Record yourself.
- Choi Siwon’s method: Find a language exchange partner and practice code-switching — English for 15 minutes, then Korean, then English again.
If you’re advanced (B2–C1, aiming for IELTS Band 7+): Combine methods.
- Watch a show (RM’s method) + explain what you watched to someone (Gong Yoo’s method) + use those insights in a real conversation (Choi Siwon’s method).
The Real Secret? It’s Not a Secret
Every Korean celebrity on this list learned English the same way you can: through real material, consistent use, and a reason to communicate in English.
The celebrities had advantages (access to international opportunities, professional motivation), but the method isn’t special. It’s just English used in context, not English studied in isolation.
If you want to reach the fluency level of these celebrities, you don’t need a different method. You need to:
- Pick real material you actually enjoy (not a textbook)
- Commit to using it regularly (not sporadically)
- Practice in real conversations (not just passive listening)
