The mother of Ludacris' baby daughter is suing the rapper for child support.

The Area Codes hitmaker, real name Christopher Bridges, became a new father on 9 December (13), and now he's at the centre of a paternity battle with the child's mum, Tamika Fuller.

She filed legal papers on Friday (03Jan14) in response to Bridges' efforts to put a $1,700 (Gbp1,100)-a-month cap on his child support obligations.

Fuller claims the rap star should be forced to pay more - because he spends roughly $7,000 (Gbp4,600)-a-month on lawn care and $5,000 (Gbp3,330)-a-month on his pets.

She is also demanding Ludacris pays her legal fees, so she can afford to hire a good attorney.
