The X Factor

The Wanted are gearing up for their world tour and new album, pulling out all the necessary stops to get on top. The boy band performed their latest U.K. single, 'Show Me Love,' on 'X Factor U.K.' -- the "birthplace" of rivals One Direction!

Following her self-imposed Twitter hiatus, it's suspected that Demi Lovato is back in rehab.

We'll still have to wait until next month to hear Bruno Mars' complete 'Unorthodox Jukebox,' but the frequently hatted singer helped whet our appetites for his second album with a recent appearance on the U.K. version of 'X Factor' -- complete with a live performance of the set's leadoff single, 'Locked Out of Heaven.'

After months and months of speculation, it’s finally official. Britney Spears has joined ‘X Factor‘ as a judge for $15 million. Also confirmed is Demi Lovato, whose name only recently came into the picture as a possible judge. Prof? Well, the photo, tweeted by Simon Cowell.

The axe — or is that the ‘X’ — fell at ‘X Factor‘ yesterday (Jan. 31), with judge Nicole Scherzinger being fired, along with host Steve Jones. Sources indicate that judge Paula Abdul was also cut. Word is producers and Simon Cowell were looking to make a fresh start for the show, whose ratings fell below expectations on Season 1.

It's the reunion we've all been hoping for. In an exclusive interview with Deadline's Nikki Finke, former 'American Idol' judge Simon Cowell revealed he wants Paula Abdul to join the judges' table on his upcoming reality series 'The X Factor.' "I've always wanted Paula. Always been very vocal about that. I missed her the second she left the show," he said. "Always loved working with
