Nicole Scherzinger nearly popped out of her black satin dress Saturday night at the Captial Radio Jingle Bell Ball at London's O2 Arena. The sexy Pussycat Dolls singer was in town promoting her new single, "Poison," and she performed the song at the Ball.

The song is the debut single from her upcoming as-yet-untitled solo album, produced by Red One and featuring Ne-Yo and Jay Sean.

After the big show, Nicole headed over to Mahiki, a London bar, with 50 guests in tow and rang up a $150,000 bill according to

Model/actress Kelly Brook and Glee stars Mark Salling and Cory Monteith were reportedly also in the club; which Nicole stumbled out of at 4am.

We're not sure what the deal is with her hair lately either. It's the second time in the last week she's worn it like this. Perhaps she's gearing up for her role in Men In Black III.
