Britney Spears' Justin reunion

Britney Spears and Justin Timberlake are finally set to record a duet. The 'Toxic' singer and her ex-boyfriend, who have been the subject of rumours they will record a song together for months, are to reportedly team up for a track on Britney's new album, due to be released later this year.

The pair were supposed to collaborate on a track for Britney's last LP 'Blackout' but she missed the recording session scheduled at producer Timbaland's studio.

At the time, a source claimed Britney "just didn't show up". Britney's father Jamie - who is currently acting as co-conservator of her estate - is said to be keen for one time sweethearts to reunite.

Earlier this year, it was reported Jamie had asked Justin to perform with Britney, but the 'SexyBack' singer had refused.

At the time, a source said: "Jamie wanted Justin to help Britney. For a time Justin seriously considered doing a couple of concerts with her to help her out."

As well as a duet with Justin, Britney's next album is set to include a song she has written about her sons - Sean Preston, two, and 23-month-old Jayden James. The troubled star revealed: "I've written a song for my next LP about them called 'My Baby'. It's a beautiful song, I'm really proud of it."
