American actor John Stamos is dating again, three years after he split from ex-wife REBECCA ROMIJN. The 44-year-old, who has been single since he separated from Romijn in 2004, has been enjoying a series of dates with fashion worker Leah Marsh, who he met through mutual friends. An insider tells OK! magazine, "It isn't too serious. They've been dating over a month and enjoy hanging out. John's in no rush to settle down again."
