Many celebrities gave a glimpse of their festivities through personal photos that revealed how they got into the holiday spirit at home such as Snooki and the Kardashian and Jenner sisters. Other celebrities posted sexy photos of themselves like Fergie and Josh Duhame. Katy Perry also posted a photo of her beau John Mayer as her "Santa Baby."

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.

Christina Aguilera has the vocal chops, the look, the strut and millions of new fans thanks to her stint as a judge on TV singing contest "The Voice."

Jimmy Fallon made an unusual performance with his guest Christina Aguilera on Monday, Nov. 5. The late night talk show host and his house band, The Roots music group, joined Aguilera for an eclectic performance where together they used office supplies for instruments for her performance. Fallon opened the set for "The Voice" mentor by using his cell phone's beeps which served as the background music for Aguilera's vocals which she supported with a stapler. In the video below, the comedian and Grammy singer used a variety of office supplies to substitute instruments-a tape dispenser, Kleenex box, iPhone and a water jug.
