Christina Aguilera thinks that Britney Spears will be a "great" X Factor judge.

The "Fighter" hitmaker - who is also a coach on singing contest The Voice - wishes her former All-New Mickey Mouse Club co-star well in her new role on the rival talent search show. "I came up with Britney. Mickey Mouse Club, we were very close. Our paths have always crossed and they continue to cross. I welcome her to this family of fun and entertainment and finding new talent. I don't know what she's going to offer specifically, but I know she's a pro and she's going to give, I think, great advice."

As well as Britney and Demi Lovato being appointed to the X Factor panel, Mariah Carey was recently announced as a new judge on American Idol and Christina thinks it is great to have so many women in such high-profile roles: "I welcome these very talented women. You know this business, especially in my genre of pop, [people] pit us against one another and women against women and this and that. I'm not down for that. At this point in my life, I have no patience for it. So, I'm like, come in, the more the merrier."
