"I like to keep it fresh and interesting," Aguilera told Us Weekly in April of her approach to fashion. "I get bored and I'm an artist first and foremost. I'm from the world of making videos and touring and I love theatrics."

Aguilera isn't the first star to don the skintight Herve Leger by Max Azria dress. Partners actress Sophia Bush, 30, paired the look with black pumps at the Art of Elysium Genesis celebration in L.A. on October 10, 2009, and E! reality star Khloe Kardashian, 28, wore the same design at Beach Bunny Swimwear's grand opening party in L.A. on April 27, 2010.
