Hip-hop artist Nas has filed a response to Kelis’s divorce filing, asking a court to deny her any spousal support, court documents filed in Los Angeles show.

Kelis, 29, the “Milkshake” singer who’s pregnant with their first child due in July, filed for divorce from Nas, 35, last month. Both sides are seeking joint custody of the unborn child.

Although the couple went public with their marriage with a ceremony in 2005, the pair was secretly married at a courthouse in 2003, a source confirms.

(It is believed that the pair are divorcing because Nas was cheating on her…while she was pregnant. Guess he didn’t remember that she first became famous for singing Caught Out There, a song about her freaking out on a cheating boyfriend.)
