On Infinity Challenge Kwanghee sang Fantastic Baby with G-Dragon and Taeyang. When it came to Seungri's part G-Dragon cut it off then said it was enough. Kwanghee protested saying he was good at singing Seungri's parts. G-Dragon says that our Seungri is really good. Kwanghee is good but Big Bang's Seungri is REALLY good. Aww G-Dragon is so cute!
