Whoa... someone hire a wardrobe consultant for this celeb- and make it quick! Fergie showed up for Total Request Live on June 18th with greasy hair, dressed like a backup dancer in a 1980's Jane Fonda workout video.

Clad in high-waisted, faux demin pants with suspenders, Fergie performed her new single, "Big Girls Don't Cry." Well Fergie.. big girls might not shed tears, but my grandpa might because he wants his suspenders back.

Be nice to grandpa...

Fergie is scheduled to appear in the Music Rocks concert at Radio City Music Hall September 6th. Rumor has it she'll be transported to the red carpet in a Delorean.
