Who Bum Rushed Ludacris On Stage Last Night?

No worries! It was just Justin Bieber!

The Biebs made a surprise appearance at the Black Eyed Peas concert at the Staples Center last night during Ludacris‘ opening act. Justin took to his Twitter after the gig to say:

“Crazy night…got to surprise the crowd at the STAPLES CENTER with @Ludajuice 2nite!! Black Eye Peas killed it too.”

Baby, baby, baby OH! What a special something, something for all you fans!

Any of U in the audience? How did the Biebs sound?
