PictureLux on the red carpet report: "Burlesque" premiere.

Christina Aguilera and Cher attended the premiere of their film 'Burlesque' on Monday (November 15, 2010) at Grauman’s Chinese Theater in Hollywood.

The 29-year-old singer looked gorgeous in an Elie Saab emerald green empire waist silk chiffon gown and Neil Lane jewels.

Cher, 64, debuted a more risque outfit - stepping onto the red carpet in a sparkly black dress with a plunging neckline, very high hemline and lacy bra.

Director Steven Antin beamed over his supporting cast Julianne Hough, Cam Gigandet and Stanley Tucci as well as Celebrity well-wishers including Will Ferrell, Jane Fonda, Kathy Griffin, Patricia Clarkson, Debi Mazar and AnnaLynne McCord among others. Chaz Bono, Cher's son, showed up with girlfriend Jennifer Elia.

Earlier in the day, Aguilera received a star on the Hollywood Walk of Fame. Hundreds of fans jammed a Hollywood Boulevard sidewalk to watch as Aguilera gushed with delight as her star was unveiled in front of the Hard Rock Cafe. (Photo by © 2010 Joe Martinez/PictureLux)
