Keshia Knight Pulliam

‘Cosby’ kid Keshia Knight Pulliam threw the first punch in her impending child support case against former NFL player Edgerton Hartwell.

Pulliam, who is 4 months pregnant, retained the services of Atlanta family court specialist Tanya Mitchell Graham, ESQ. to represent her in the divorce case.

As you know, Hartwell, 38, filed for a divorce in Fulton County in July after 6 months of marriage to the 37-year-old actress.

The divorce action came 1 week after Pulliam happily announced her pregnancy on Instagram.com.

But in his divorce petition, Hartwell requested alimony and a paternity test to rule him out as the father of Pulliam’s unborn fetus.

In a recent interview with ET, Pulliam seemed confident that Hartwell was indeed the father of her unborn baby.

That’s probably why she retained Mitchell Graham, who successfully represented singer Ciara Wilson and rapper Christopher “Ludacris” Bridges in prior child support and child custody cases.

On Thursday, Pulliam filed notice in Fulton County Court that she dismissed her attorney and retained the services of Mitchell Graham.
