Kelis Delays Show to Avoid Nas

'Bossy' singer Kelis boldly attacked PETA for critical statements they made about her choice of wardrobe, and has been extremely aggressive in her pursuit of child support payments from her former husband, Nas. Though the couple were pictured together just this past September, Kelis has allegedly turned shy when it comes to meeting her ex in public.

Gossip website Bossip.com claims that the two performed at the acclaimed Sundance Film Festival in Utah last week, with Nas playing at Harry O's, while Kelis followed John Legend, rocking the Film Lounge at House of Hype.

According to Bossip's source, Kelis did everything in her power to avoid Nas, delaying her performance until well after Nas finished his set, because "she didn't want to compete against her ex." The former hip-hop sweathearts have grown progressively more estranged as their battle over financial support has gone on. We hope they reach a reconciliation for their son's sake.

In the meantime, the two artists are more than likely to come head-to-head this spring when they both drop new albums. Nas' forthcoming album with reggae artist Damian Marley, 'Distant Relatives,' is scheduled to be released in April. Kelis is currently working on new material with a "futuristic disco sound" for her forthcoming album, 'Fleshtones,' which she says will see release via Interscope this spring.
