Kelis is finally using her milkshake for what god intended - feeding babies, not bringing the boys to the yard. 'Bout time too, the little strumpet. The singer had her kid, which is cool because she might now go back to being hot again... probably not though. Babies suck.

"Milkshake" singer Kelis is a new mom! The singer, 29, gave birth to baby boy named Knight on Tuesday.

"My son is born today, so shout-out to my son, Knight," said Kelis' ex, rapper Nas.

The couple called it quits in May after Kelis, then 7 months pregnant, filed for divorce citing verbal abuse and infidelity, according to Vibe, which first reported the break up.

Us Weekly exclusively revealed Kelis' pregnancy last January. At the time, she was still married to Nas, 35, who is also dad to a 15-year-old from a prior relationship.

"It's all they are talking about," a source told Us at the time of Kelis and her ex. "She is carrying hip-hop royalty! They are so excited."

Ok, so first this kid was royalty, and now he's only a Knight. Dude's being demoted faster than he can grow up. By the time he's five he'll be known only as Peasant. Actually, that's a pretty cool rap name. I can see it now: "Peasant's debut album, 'Half The Kingdom', featuring The California Serf Posse." Awwwww yeah... Ok, I clearly know nothing about rap. White boy in the house!

Apparently a "milkshake brings all the boys to the yard", unless that delicious drink is being prepared to keep babies alive - then it makes them run, screaming. E! News is reporting that pregnant 'Milkshake' singer Kelis is getting divorced from her husband of just over four years, hip-hop star Nas.

"I can confirm that she has filed for divorce," Kelis' rep said. "We request the media to respect her privacy during this very difficult time."

Oh yeah, like the media respects anything. The Rhianna-and-Chris-Brown-knockoffs are apparently on the rocks, even though earlier this month Nas acted like everything was fine in an interview with MTV News.

"She's great man. She's doing good," he said of his pregnant wife. Nas said the two were working on a name for the baby. "It's kind of hard. I've been thinking about kinda putting something online: 'Choose his name.' (If you win), you get a couple stacks for that. We take care of you for that. You win something real. But we're thinking now."

I hear Nas is changing that contest now. He's either going to hold a, 'Choose my divorce attorney so I don't get screwed' or, 'Help me prove that kid's even mine. Kelis is a huge whore. It's true, one time I caught her in bed with two guys,' contest. I hope I win and get 'a couple of stacks' for it, whatever the heck that means.
