The rapper, whose real name is Christopher Bridges, became a new father on Dec. 9, and now he's at the center of a paternity battle with the child's mother, Tamika Fuller.

She filed legal papers on Friday in response to Bridges' efforts to put a $1,700 a month cap on his child support obligations, reports TMZ.

Fuller claims the rap star should be forced to pay more, because he spends roughly $7,000 a month on lawn care and $5,000 a month on his pets.
