Fergie Takes the Stage For Slash's Birthday

Fergie got down and dirty last night as she helped to celebrate former Guns N' Roses and current Velvet Revolver guitarist Slash's 43rd birthday.

Dragging her actor/fiance Josh Duhamel along for the evening in Las Vegas, the Black Eyed Peas frontwoman took to the stage alongside the guitar legend at a concert at Bare Pool & Lounge outside of The Mirage Hotel and Casino.

Following their performance, Fergie hopped off stage - joining her Transformers star hubby as they mingled with fellow party attendees.

As a follow-up to the birthday concert, there's another party slated for this evening (July 24) at JET nightclub - with a special acoustic performance by Slash followed by music spun by DJ will.i.am.
