WATCH: Britney Spears Sings 'Happy Birthday' To LA Reid On 'The X Factor USA' (VIDEO)

Has Britney Got The X Factor?

After watching Britney Spears mime her way through her last tour we're pleased to confirm that the lady can still (kinda) hold a tune.

Britney was captured singing Happy Birthday - complete with her trademark wobbly vocal stylings - to her fellow X Factor USA judge LA Reid in a new clip from the show.

She even got a little bit of help from her boyfriend and manager Jason Trawick who joined in with Brit, although we don't think he'll be signing a record deal any time soon. HOW uncomfortable does he look?
