X-tina to Perform at AMAs

Things keep getting better for X-tina fans!

Us Magazine reports the Dirrty girl will perform a 7-minute medley of her greatest hits at The American Music Awards on Nov. 23rd.

She'll reportedly perform "Genie in a Bottle,' "Fighter," "Beautiful," "Dirrty," and her latest single "Keeps Getting Better."

"We are very excited to have Christina Aguilera perform at this year’s show," Dick Clark Productions President Orly Adelson said.

"She raises the bar with each live performance and you can expect something special at the 2008 'American Music Awards.'"

This is only the second time X-tina's performed since giving birth to son Max almost a year ago.
