* G-Dragon: He has studied English and has been known to use it in interviews and social media posts. He is comfortable with basic conversation but doesn't appear to be fully fluent.
* T.O.P: He has a good understanding of English and can hold conversations. He's known for his love of American culture and has even spoken English in some music videos.
* Taeyang: His English is good enough for basic communication, but he primarily communicates in Korean.
* Daesung: He has studied English but doesn't seem to use it often publicly.
* Seungri: His English proficiency is similar to Taeyang's.
It's important to note that "fluency" is a subjective term. While the members of BIGBANG may not be able to hold long, complex conversations in English, they're all capable of communicating in a basic way and understanding English.
