Nas photographed with Kelis-inspired wedding dress

Nas has sparked speculation about his feelings for ex-wife Kelis after releasing the cover art for his new album, in which he poses thoughtfully with a green gown that looks like the one his former bride wore on their wedding day draped over his lap.

In an accompanying online video, promoting his 10th album, Life Is Good, Nas confirmed the image is a Kelis reference - posting a clip from his recent Behind the Music episode in which he spoke about his divorce, explaining, "She (Kelis) took her stuff out of the house and left her green wedding dress, and that was all she left."

But Nas has refused to expand on his current thoughts about his ex.

The couple wed in 2005 and divorced in 2010.
