LOS ANGELES - Kelis and Nas are calling it quits.

Kelis Rogers filed for divorce Thursday in Los Angeles. She's expecting the couple's first child in July.

Documents show they were married in July 2003 and separated in April. Rogers is seeking to have her hip-hop husband pay her lawyer's fees and spousal support.

She cited "irreconcilable differences" as the reason for the split.

Nas' real name is Nasir Jones. He is considered one of rap's best artists and received a Grammy nomination for his latest untitled album. Kelis may be best known for her hit single "Milkshake."

His publicist did not respond to an email message seeking comment.
