Although a new fall television season is days away from launching, two high profile celebrity couples' marriages have been cancelled. Family attorneys in Pasadena have been watching celebrity couples break up all summer long, and a pair of TV stars are the latest to engage in divorce, Hollywood style. Elisabeth Moss, who plays beleaguered copywriter Peggy Olson on AMC's hit drama Mad Men, and her husband Fred Armisen from Saturday Night Live announced their divorce last week, while Patricia Arquette of Medium fame and Thomas Jane, star of HBO'sHung, went forward with their divorce after reconciling earlier this year.

Armisen and Moss were married in October 2009 after rumors that the notoriously shy couple had been dating for months. The couple exchanged vows in front of family and friends at the Foundry on Long Island. In keeping with the pair's press-shy history, Life Style magazine reports that Moss and Armisen actually have been separated since May. Moss is finishing her fourth season on Mad Men in Los Angeles while Armisen splits his time between Portland, Ore., and New York while working on the new series Portlandia before returning to a another year of SNL.

Meanwhile, the near decade-long relationship of Jane and Arquette has ended -- again. Despite reuniting after a separation last year, the couple is going ahead with a divorce. (Arquette originally filed for divorce in January 2009.) The actors met through mutual friends in 2001, had a child, Harlow Olivia Calliope, in 2003 and married in May 2006. A rep for Jane told People magazine, "The split is completely amicable and their prime focus is their daughter." Arquette currently is attached to the latest Richard Linklater film while Jane has spent the summer promoting the second season of Hung.
