Lady Gaga is understood to have collaborated with Rihanna on the singer's forthcoming new album.

An scan showing the CD's tracklisting has emerged online and suggests the pair have recorded a song together entitled 'Broken Heels'.

The album, entitled 'Loud', is released on November 15 and also features previously confirmed collaborations with Drake and Nicki Minaj.

Speaking of her collaboration with Drake, Rihanna said: "We may even shoot a video for it. I went out with him, Trey [Songz] and J. Cole recently. We had a lot of fun."

Meanwhile, Rihanna has released the official video for 'Only Girl (In The World)', which is the first single to be taken from the album.

'Loud' is the follow-up to the singer's 2009 album 'Rated R'.
