Hip-hop star Nas and his wife Kelis are reportedly expecting their first child together, said reports by Us Weekly.

A source told the magazine that the singer is currently in her first trimester, and she's already showing.

"It's all they are talking about," said the source. "She is carrying hip-hop royalty. They are so excited."

While it will be Kelis first, Nas already has a daughter, named Destiny, from a previous relationship.

The couple have been married since January 2005, after being engaged for nearly two years. The pair married in Atlanta.

Both stars have yet to comment on the reported pregnancy.
