Guess Who's Knocked Up?

Yup the girl whose "Milkshake" brought all the boys to the yard is expecting her first child with hubby Nas.

Read what an insider told US Weekly:

“It’s all they are talking about. She is carrying hip-hop royalty!” says the insider, who adds Kelis — currently in her first trimester — already has a little bump. “They are so excited.”

How cute...It's about time they have been married for a couple of years now.
