It feels like decades ago when we outed Miami Heat's golden child Dwyane Wade and Gabrielle Union after a little rendez vous at the Ritz Carlton Key Biscayne. Since then, Wade and Union have never officially admitted they were an item, but actions spoke louder than words. Proving that point is Wade's ex wife Siohvaughn Wade, who has just filed a lawsuit against Union for inappropriate conduct around the estranged couple's young children. According to the Chicago Sun Times, the ex Mrs. Wade "claims Gabrielle Union 'engaged in sexual foreplay with Dwyane Wade' in front of Wade's 8-year-old and 2-year-old sons while on an unsupervised visitation to the basketball star's Miami home." The lawsuit, which was filed Tuesday in Cook County Circuit Court, also claims that Wade's oldest son was "allowed to play unsupervised in or around the Miami home's pool at night. Wade and Union ignored the boy, whose 'screams and cries' eventually got the attention of Wade's mother, Jolinda Wade, who took the boy inside." The lawsuit goes into other claims, all involving the safety or lack thereof of their children. Ex Mrs. Wade is seeking more than $50,000 from Union, but we have a feeling it has nothing whatsoever to do with the money.
