Christina Visits the Acting World in 'Burlesque'

Aguilera had popped up in a few acting cameos before "Burlesque," but the 2010 film represented a bold foray into the acting world for the pop singer, as well as a chance to learn a new craft from Cher, one of the most successful crossover singer/actresses ever. ""Cher taught me about how, for your off-camera scenes, [you should] be just as good if not more of an actor [for] the person you're in the scene with. It's going to make the whole thing better -- to really be a giving actor," Aguilera recently said at the Billboard/Hollywood Reporter Film & TV Conference. During a year in which her fourth album, "Bionic," underachieved, "Burlesque" offered a bright spot for Aguilera, who received positive reviews in her first major role.

Christina Finds 'The Voice'

Five months after the release of "Burlesque," Aguilera hopped from film to TV on "The Voice," a new reality competition executive produced by Mark Burnett. Starring alongside Cee Lo Green, Maroon 5's Adam Levine and Blake Shelton, Aguilera was given the opportunity to coach prospective vocal talent on a weekly basis, as well as showcase her personality on a fresh platform. Now in its third season, "The Voice" remains a ratings giant, while Aguilera and Levine used the show to help launch their collaborative single "Moves Like Jagger," another Hot 100 chart-topper for the pop star.

The 'Lotus' Rebirth

CHRISTINA AGUILERA LOTUS

With her fifth album, "Lotus," Aguilera has synthesized the various shades of her career into a single color: first single "Your Body," produced by new collaborator Max Martin, offers the sexy playfulness of "Dirrty," while "Army of Me" is the "Fighter" for a new generation of pop fans. The album gave Aguilera another Top 10 debut on the Billboard 200, and after exhibiting her stage prowess at the 2012 American Music Awards, Aguilera plans to take "Lotus" on the road in 2013. It's a fresh start for a veteran artist who continues to redefine her legacy.
