Gwen Stefani rocked YSL when No Doubt hit the Teen Choice Awards pink carpet!

Gwen Stefani and her bandmates from No Doubt are known for their crazy-cool red carpet and stage get-ups, but with time comes change and oh, what a change they debuted on the fuchsia carpet last night for the 2012 Teen Choice Awards.

Tom Dumont, Adrian Young, Gwen Stefani and Tony Ashwin Kanal arrived at the Gibson Amphitheatre looking super chic in a black, beige and gold ensemble across the board. While they predominantly wore black, I’m digging Adrian’s neutral pop with his brighter blazer and vest — and those olive green combo shoes!

Gwen rocked a black leather biker top with gold hardware and matching black slim trousers from Yve Saint Laurent. She paired them with leather Christian Louboutin “Pigalle” pumps, but added a gold element with an anklet over her pant leg.

With her bright blonde hair ironed sleek and parted to the side, she finished off her look with edgy gold jewelry by XIV Karats, oversize arched sunglasses and her signature red matte lip.

For No Doubt’s reunion performance of their new single “Settle Down”, Gwen hit the stage in black and white printed custom L.A.M.B. trousers, a black Rick Owens tank top and Dr. Martens leather lace up boots.

I love her black and white chunky layered bangles to match her checkerboard manicure!

Is there any doubt that Gwen and the gang totally rocked the TCA carpet and stage?
