Move over Jennifer Lopez! Christina Aguilera’s bootylicious new figure is all the buzz in town.

X-Tina, as the songstress calls herself, channeled her inner JLO as she presented the nominees for the upcoming American Music Awards on Tuesday in Los Angeles, donning a tight purple mini-dress that clung to every curve on Aguilera’s body.

The “Dirrty” singer had all eyes on her as she smiled and posed for photos, according to the Daily Mail. She paired up her colorful dress with platinum heels, pink nail polish and pink hair-dye on the tips of her beach-blonde hair.

“The Voice” coach is the first artist confirmed to perform at the star-strutted event taking place on Nov. 18.

Last year, Lopez was the talk of the awards ceremony as she put on a performance of her latest singles and sensually danced in rhinestone-covered ensembles. JLO also took home the Latin Artist of the Year award.

For the 2012 awards, Pitbull is once again in the running for favorite male artist in the pop/rock category. The Miami-born rapper is up against teen-sensation Justin Bieber and fellow Floridian rapper Flo Rida.

Pitbull will also duke it out with Don Omar and Shakira for the favorite Latin artist honor.
