The woman behind the lawsuit is Siohvaughn Wade -- the mother of Dwyane's two sons. Siohvaughn just filed a new lawsuit, on behalf of the two minor children (an 8-year-old and a 2-year-old) -- claiming Wade has engaged in "extreme and outrageous conduct" with his new GF Gabrielle Union in front of Wade's two children.
But Wade tells TMZ, "I am shocked that Siohvaughn Wade has brought this baseless and meritless lawsuit in the name of our children against Gabrielle Union."
Wade adds, "I am deeply saddened and disappointed that Siohvaughn has used our sons once again as pawns and is now lashing out at Gabrielle, who is an innocent party. It is clear that this is a desperate attempt to retaliate against me for seeking sole custody of our children and requesting that the court have her undergo a psychiatric examination."
Wade concludes, "My primary concern is my children and actions such as this only inflame the situation and are harmful to their well being.”
UPDATE: TMZ just spoke with a rep for Gabrielle Union who also rejects Siohvaughn's claims -- and apologizes to the court system for having to deal "with erroneous claims when there are real victims who should be receiving the legal attention they need."
