EDDIE MURPHY's baby drama: Coming soon to a courthouse near you? His ex MELANIE BROWN, 31, tells Insider she's ready to play hardball with the Shrek the Third
star—whom she claims fathered her 1-month-old daughter Angel Iris Murphy Brown. "He's not doing a DNA test and he's not signing the birth certificate," Brown (a.k.a. the former Scary Spice) said at the L.A. Boots launch party. "So [I'm] going to have to go to court so he can be forced to do it. It's strange since he was the one asking for [the test]." Meanwhile Murphy, 46—now dating TRACEY EDMONDS—has remained mum on the matter while promoting his animated film. His rep could not be reached for comment.
