BIGBANG’s Seungri said that he’s not really in need of any dating advice on the June 30 episode of Naver Star Cast’s ‘Countdown Live’.

One fan asked G-Dragon for dating advice, and the BIGBANG leader then suggested that Seungri get involved. Seungri responded, “I don’t have anything I’m worrying about. To be honest, when I’m dating I don’t have problems.” After the group’s latest song “If You” played, he also revealed, “I broke up with someone recently, so this song is even more sad.”
Taeyang then said, “I have a cheerful personality, so I’m not sad even if I break up with a girlfriend.”
