NBA superstar Dwayne Wade and his former girlfriend, actress Gabrielle Union, are still friends. As you know, the former lovebirds quietly split up a few months ago. But their breakup came to light when she didn’t attend game 6 of the NBA Finals in Miami. In fact, trouble at home was believed to be the reason D. Wade didn’t give his all on the basketball court. But Wade and Union sent each other lighthearted tweets today on the social networking website Twitter.com. Wade, 29, is in Milan, Italy with his stylist attending Milan Fashion Week events, while Gabby, 38, is off somewhere in the deep woods of the midwest filming a movie.
