There was something different about Fergie at Tuesday's Wolverine premiere.

Posing on the red carpet alongside her Black Eyed Peas bandmates apl.de.ap, will.i.am and Taboo, the singer looked stunning in a futuristic silver mini-dress.

But close up, the Fergalicious one looked rather plump and stretched of face, inviting speculation she's had botox or fillers, if not a more invasive procedure.

Although, she seems to have missed a bit and was looking a little wrinkly around the neck and armpit area (see below.)

Fergie has previously blasted reports she's undergone cosmetic surgery, calling the claims “completely untrue.”

Back in 2005, she said: "I haven't had any surgery but I would maybe consider a nip and a tuck. I've been sun tanning forever and damaging my skin.

"I would be open to botox."

Judging by our photos, she's well and truly got the ball rolling on that one.
