Ne-Yo's "former" baby mama may sue him for putting her on blast during his "Behind The Music" special. Find out why inside and get the details on Hines Ward claiming paternity....

Remember that "Behind The Music" special where Ne-Yo revealed he paid off "former" baby mama Jesseca White (not the famous model Jessica) AFTER he discovered the child she claimed was his, really wasn't?  Well....we were NEVER supposed to learn that Jesseca "might" had led him on in terms of paternity or that she no longer communicates with him.  The situation didn't cast her in the best light and that's clearly why they had a confidentiality agreement in place.

Either Ne-Yo didn't care of maybe he forgot about it when he dished all the dirt on his VH1 Behind The Music episode. But Jesseca and her attorney Gloria Allred are up in arms...and seeing green $$$. In addition to the $575,000 he paid her in 2009, Jesseca is threatening to take Ne-Yo to court for violating their agreement since she claims she's been "defamed, ridiculed and harassed."

Jesseca is also claiming that she's been unable to work, was mentally distraught and "beset by nausea, vomiting and hair loss" since her past was exposed.

So now she wants more money or she says she'll pursue other legal options.

We'll keep you posted.....

In other baby daddy drama.....

Remember that "paternity" claim that popped up for Hines Ward in Georgia?  It turns out that Hines has claimed paternity and is filing court documents to make it official.  Hines has submitted to a blood test to prove he is the father of Jordyn, a girl born to Melanie Smith in January 2011.

Hines plans to provide child support (and said he's already started) and wants joint legal and physical of little Jordyn.
