Travis Barker, of the Transplants and blink-182 fame, filed for divorce this morning from his wife of 22 months, Shanna Moakler. "I can confirm that Travis filed this morning,"Barker's rep, Dvora Vener, told People magazine. Moakler, 31, a former Miss USA, and Barker, 30, co-starred in MTV's Meet the Barkers reality show. Rumors of a split, which escalated in early July when the Barkers put their 12,000-sq.-ft. Tuscan villa in Bel Air, CA on the market, had been circulating for months. The pair have two children together: son Landon, 2, and daughter Alabama, 7 months. Moakler, who was once engaged to boxer Oscar de la Hoya, has a daughter, Atiana, 7, from that relationship. "My only concern right now is for the welfare and best interests of my children," Moakler told the magazine via her publicist.

Barker and Moakler join a growing list of MTV reality show couples, including Nick Lachey-Jessica Simpson (Newlyweds) and Carmen Electra-Dave Navarro ('Til Death Do Us Part), who've split.
