On Thursday afternoon, attorney Laura Wasser (who has also represented Britney Spears) filed a divorce petition on behalf of Kelis, citing irreconciable differences. Vibe.com posted the petition on its site.

The news comes mere weeks after Nas spoke excitedly with MTV News about the baby. When asked earlier this month how Kelis was doing, he said, "She's great, man. She's doing good. [We are deciding between] a few baby names. It's kinda hard. I've been thinking about kinda putting something online: 'Choose his name.' You get a couple stacks for that. We take care of you for that. You win something real. But we're thinking now."

Nas and Kelis first met in 2002 at an MTV Video Music Awards afterparty thrown by Sean "Diddy" Combs. The couple dated for two years and were married in Atlanta in January 2005
