Britney Spears has recorded a song for the new 'Smurfs' movie.
The 'Toxic' hitmaker worked on 'Ooh La La' for her children, Sean, seven, and Jayden, six, with ex-husband Kevin Federline, but has now revealed the track will be part of the soundtrack for 'The Smurfs 2', the forthcoming sequel to the 2011 animated adventure.
She announced on both Facebook and Twitter: ''Remember that surprise song I recorded for my boys? It's coming soon! #OohLaLa for #TheSmurfs2 :) (sic)''
While details about the track are not yet known, it is possibly Britney has teamed with her 'Scream & Shout' collaborator will.i.am again as earlier this month the Black Eyed Peas star tweeted they had been ''bonding''.
He wrote: ''I had a good vibe session during lunch with .@britneyspears today ... talking about music, dreams, and life...#bonding (sic)''
And last month, the pair spoke of their desire to work together again.
After hearing will's new song '#THATPOWER' with Justin Bieber, Britney tweeted: ''@JustinBieber @IAmWill got #ThatPower!! I am in L-O-V-E with the new song! (sic)''
will.i.am replied, saying: ''Thanks so much @BritneySpears. I can't wait 2work with u (sic)''
'Scream & Shout' producer Lazy Jay - real name Jef Martens - has said how it felt ''surreal'' when he got a call from will.i.am asking to use one of his productions with the pop icon.
He said: ''One night I was just working in my home studio in Holland and I received a phone call and I wasn't sure who it was.
''When I picked up, it was will.i.am. I couldn't believe it. He said, 'Hi, it's will.i.am from the Black Eyed Peas, I've heard some of your stuff and I think it's really dope and I want to make record with you and Britney Spears. Is that OK?' Of course, I said, yes. It was a surreal moment.''
will.i.am - who is also a member of the Black Eyed Peas - has also previously worked with Britney, on the track 'Big Fat Bass' from 2011's 'Femme Fatale' album.
