Usher reportedly filed for divorce from his wife of less than two years, Tameka Foster-Raymond, the AP reports. The 30-year-old Confessions singer filed the petition in an Atlanta Superior Court, and no details regarding the split were revealed. Usher marred Foster, who was previously his stylist, at a lavish Georgia ceremony in 2007, and the couple had two sons together. However, according to MTV, the pair had been pretty much separated for some time, and Usher was recently seen in paparazzi photos partying at a nightclub in Las Vegas. Earlier this year, Foster suffered cardiac arrest while undergoing a plastic surgery procedure in Brazil, forcing Usher to cancel his performance at Clive Davis' pre-Grammy party.
