One quarter of popular group the Black Eyed Peas, Fergie, celebrated bandmate Alp.De.Ap’s 37th birthday while wearing stunning silver earrings and a tight leather dress.

Accompanied by hubby Josh Duhamel, the power couple impressed photographers as they posed outside LA club The Conga Room.

The singer’s long blonde locks cascaded down her back, however, her silver earrings dangled just enough for her to inspire women in search of online jewellery.

Fergie maintained her rocker-chick image in the leather piece, so in style right now, but showed she was beyond her wild years as she kept her make-up to a sassy minimum.

While the dress was silver studded, adding to its biker-girl appearance, her feet were neatly slipped into shiny black heels that added to her height.

Grasping a sparkling clutch handbag, the 36-year-old looked more than smitten with Duhamel, who is set to appear in 2012’s Fire with Fire.

Fergie took to American screens earlier this year after she appeared on Late Night with Jimmy Fallon.
