"Burlesque" leading ladies boasted completely different looks at the Los Angeles premiere of their highly anticipated film Monday evening, but Christina Aguilera and Cher both accessorized in one very similar way -- they weren't afraid to show cleavage.

Aguilera, who arrived first in an ethereal Elie Saab emerald green empire-waist gown, wore her blonde locks loose and wavy in a half updo, with her signature red lipstick firmly planted on her pout.

The newly single 29-year-old is having quite the month, not only attending the premiere of her first feature film but also receiving a star on the Hollywood Walk of Fame and launching two fragrances aptly named Christina Aguilera and Christina Aguilera By Night on Nov. 1. Time to check a few things off that bucket list, lady!

Cher hit the red carpet in her signature black, donning a glittery minidress with lace sleeves and a plunging V neckline and fishnet stockings, her raven locks left long in chunky curls.

The ensemble is strikingly similar to what the legendary diva wears on screen as Tess, the tough-as-nails Burlesque club owner with a heart of gold.

"Dancing With the Stars" darling/country crooner Julianne Hough, who plays sweet but dimwitted Georgia, strutted down the red carpet in a Grecian-inspired, gold, knee-length, off-the-shoulder cocktail dress.

Hough, who traded her usual blonde locks for a brunette do in the movie, continued to carry on the darker hue, pulling her wavy strands into a loose half updo.

For Aguilera fans who can't decide whether to spend their hard-earned cash on movie tickets or her new fragrances, which are available at Kohl's nationwide, have no fear: A limited edition gift set is currently available that not only contains both sweet scents but also a voucher for a downloadable ticket to see "Burlesque."

"Burlesque is about feeling sexy and empowering women, which is a perfect fit for my fragrances as that is what inspired me to create them," Aguilera says.

"Burlesque" opens in theaters nationwide Nov. 24.
