Christina Aguilera was one of the most buzzed-about celebrities during the 2012 American Music Awards for more reasons than one. While "The Voice" mentor never disappoints in the singing department, her visuals for her performance had show's viewers express harsh criticism online. Aguilera, 31, was surprisingly chic when she first appeared on the red carpet with a chin-length bob haircut with a purple and white ombre gown. The look was simple and stunning and received rave reviews, compared to the harsh criticism she received when she sported snake cornrow braided hairstyle with patriotic jeans and pink afro wig during a "Voice" live show last week.

Robert Pattinson and Kristen Stewart reunited again at the "Twilight Saga: Breaking Dawn-Part 2" London premiere at Leicester Square on Wednesday, Nov. 14. The movie premieres in theaters nationwide at midnight on Nov. 16., and the reviews have mostly given the last film of the "Twilight" franchise two thumbs up! With Bella and Edward having a half-vampire baby, fighting the volturi and a buzzed about sex scene that almost had the movie rated-R - it's no wonder critics approved.

Christina Aguilera has outdone herself again.When Aguilera, 31, came out onstage during a live episode of NBC's "The Voice," she shocked viewers with her pink Afro wig accessorized with a tiara. The petite singer wore the same pink Afro that was a part of her sexy Halloween costume, with an equally attention-getting outfit for her duet with Cee-Lo Greene. Her cleavage spilled out of her print strapless dress with a floor-sweeping train for the live show on Tuesday, Nov. 13. The NBC mentor accented the look with star-spangled earrings, a black fur around her shoulders, and a white lace fan she held as she strut in her crystal-embellished thigh-high boots. The "Voice" judges performed her song "Make The World Move" from her latest seventh studio album, "Lotus." "About to #MakeTheWorldMove with @CeeLoGreen on @NBCTheVoice tonight. You better not miss it!!!" Aguilera tweeted before the show.

Thousands of screaming fans lined the black carpet late on Monday for the final "Twilight" film premiere as the cast of "Breaking Dawn - Part 2" bid farewell to the franchise and its loyal followers.
