Britney Spears' ex-husband Jason Alexander has remarried.Marriage records obtained by Page Six show that the notorious ex obtained a marriage license before officially tying the knot with Rebecca Bell on March 27.Jason, of course, famously eloped with Britney in Las Vegas in 2004. The marriage was annulled within 55 hours, but he later went on to claim he was "duped" into signing annulment papers. Still, despite recently marrying his new bride, Jason seems to be publicly focused on his ex, as his Instagram page is still littered with Britney-centric posts.Over the weekend, he shared a photo of a tabloid article from 2010 with the headline, "Britney's Cry For Help." "The perfect situation on the outside could be the most abusive on the inside," he wrote.
