Britney Spears pens song for Selena Gomez

Britney Spears has written a track for 'Wizards Of Waverly Place' star Selena Gomez.

The singer, who was criticised for not writing tracks off her own recent album 'Femme Fatale', has been busy elsewhere, penning the song 'Whiplash'.

The track is expected to appear on Gomez's forthcoming album which is due to for release in June, reports MTV.

In return the star, who also appeared in 'Hannah Montana', is planning to do a Britney tribute for her own tour. 

'We're gonna do a little tribute. We're gonna do her hits, ' ... Baby One More Time,' and then I think we're going to try to incorporate 'Toxic' and that phase,' Gomez added.

'And then we might do some of her recent, new stuff.'
