Britney Spears duets with her sister Jamie Lynn on her new album.
The 'Work Bitch' singer worked with her 22-year-old younger sibling on the song 'Chillin' With You' which features on her eighth studio record, 'Britney Jean'.
The 31-year-old star has revealed the tracklist of 14 songs which will be included on the album, which is set for release on December 3.
She also collaborates with will.i.am on the song 'It Should Be Easy', following their number one hit 'Scream and Shout' in 2012.
The Black Eyed Peas star recently said Britney's eagerly-anticipated new album is "one of her best".
