MBC Gayo Daejun was held on the New Year's Eve of 2011. 2NE1 and GD&TOP showed awesome performances as usual. But then everyone was surprised when Minji's voice was heard during Park Bom's part in 'Oh Yeah' and the rest of 2NE1 members showed up on stage as well where Bom came last.

Although the ending pose was different than the usual, G Dragon and Park Bom showed us "THE SIGN" (the okay sign) during High High (by G-Dragon) and Oh Yeah (by Park Bom) as seen on the photo on top.

GD: I just did the sign.. it's your turn.

Bom: Alright honey, I'm doing it! Don't mind about TOP though!
