Pregnant Kelly Rowland is getting serious about her dreams of playing late disco queen Donna Summer in a new biopic after transforming herself to look just like the diva in a new photo.

The former Destiny's Child singer has made no secret of the fact she wants to play the I Feel Love singer onscreen and she is actively campaigning for the role in director Spike Lee's film about Casablanca Records founder Neil Bogart and his stable of acts.

Justin Timberlake has signed on to play Bogart and now Rowland is hoping a photo of her looking just like Summer will persuade Lee to cast her.

Wearing a long, curly wig and Summer-esque make-up, Rowland accompanied the picture with the hashtags "#tbt #DonnaSummer-ish #LovetoLoveYa."
