The most random showbiz combo this year

18th April 2013: Just when we thought we'd heard it all, Hollywood goes and does one better.

It's the weirdest showbiz news of the year so far - Britney Spears has recorded a song for the new Smurfs movie. I know, random huh?!

She tweeted about it yesterday, saying it's a little surprise for her boys as they're both huge fans of The Smurfs. 

The song? It's called Ooh La La and will be on the soundtrack to The Smurfs 2, out at the end of July this year. 

Adam already has a pretty good idea what the song will sound like...
