Ludacris' baby mother appealing custody ruling

The mother of Ludacris' one-year-old daughter has filed an appeal challenging his recent custody win.

The Area Codes hitmaker, real name Christopher Bridges, was granted full custody of little Cai in January (15) after taking issue with ex-lover Tamika Fuller's demand for child support.

He convinced a judge he could provide the baby girl with a better home environment, but now Fuller is attempting to discredit his parenting skills by claiming Ludacris has hired a full-time nanny to take care of the tot, reports TMZ.com.

She also alleges the rapper/actor was wrong not to disclose the fact he is expecting a child with his new wife, Eudoxie Mbouguiengue.

The couple only confirmed the pregnancy earlier this month (Mar15).

The baby will be Ludacris' third - he is also a father to teenage girl Karma, from a previous relationship.
