Whitney Houston readies new album

Whitney Houston is close to finishing her comeback album, reports say.

The singer is reportedly adding the final touches to her much-anticipated seventh studio outing Undefeated, according to Hip Hop RX.

Promotional photographs of a potential album cover leaked on to the internet last week, while the first track from the album, 'I Didn’t Know My Own Strength', is expected to be given airplay in the near future.

The song is written by Diane Warren, who penned hit singles for Celine Dion, Aerosmith and Toni Braxton. Music mogul Clive Davis has also confirmed that there will be a duet featuring R. Kelly on the LP.

Houston's career has suffered in recent years amid marriage troubles and drug allegations, but she made a singing comeback at a pre-Grammy Awards party for Davis in February.
