Kristin Cavallari

The red carpet was buzzing at last night's premiere of Burlesque in LA. Christina Aguilera was dressed up in a bold green Elie Saab gown, after donning a bright white dress to receive her star on the Hollywood Walk of Fame earlier in the day. She opted for a more toned down look than her onscreen character, who plays the part in glittery eye-makeup and big hair. Cher went short and sparkly for the event and their costar Eric Dane had his wife Rebecca Gayheart by his side. Julianne Hough and her boyfriend Ryan Seacrest posed for pictures separately, though she recently gushed that "everything is wonderful" with their relationship. AnnaLynne McCord showed up solo after being spotted sneaking away from a romantic rendezvous with her ex Kellan Lutz yesterday. The musical features Christina's explosive voice and hits US cinemas on Nov. 24, then UK cinemas on Dec. 17.

Glee's Lea Michele presented an award with Joshua Jackson at the Teen Choice Awards, but last night she changed her look yet again in with straight hair and the same shoes as Nikki.
