Britney Spears: Is Christina Aguilera Making Her Nervous?

Britney Spears is set to judge the talent show The X Factor this fall, but if her behavior of late is any indication, she seems to be a nervous wreck. Could it be because shell be going up against her old rival Christina Aguilera?

Spears has made some headway in the past couple of years in her fight towards a comeback; after a much-maligned MTV performance following her breakdownwhich had critics calling her fat and druggedshe managed to get in shape and put out a new album that garnered good reviews. However, now that shes in the spotlight again, she seems to be a bundle of nerves. Those on the set of a shoot for her new perfumeElizabeth Arden Fantasy Twistsay she was constantly smoking in between takes and appeared out of it and robotic.

As the date draws nearer for Britney to sit at the judges table on The X Factor, its possible shes getting antsy about being in such a high-profile gig, and it probably isnt helping that her old rival, Christina Aguilera, is judging on a similar show opposite her. Aguilera has been on The Voice for a while now, so shes an old pro; it could be that Britney feels like she jumped into a job shes not entirely ready for.

Aguilera had some kind words for her old Mickey Mouse Club buddy, however:

I came up with Britney, we were very close, Aguilera said. Our paths have always crossed. Theyll continue to cross. I welcome her to this family of fun and entertainment and finding new talent. Britneys a pro. Shes going to give great advice.

The new season of The X Factor starts September 12th on Fox.
