CHELSEA CLINTON‘s new husband walked out on her after a knock-down, drag-out fight over starting a family, sources say, and now the former first daughter wants an annulment!

Just six months after marrying into the Clinton clan, Marc Mezvinsky has quit his cushy Wall Street job to be a ski bum in Wyoming, leaving a devastated Chelsea behind in their New York apartment, insiders say.

Now Chelsea, 30, is begging her parents – ex-president Bill and Secretary of State Hillary – to straighten out her marital mess, sources say.

"Chelsea has asked her mother and dad if they could help her get an annulment," a close source told The ENQUIRER.

"She’s heartbroken, but she isn’t afraid to end the marriage.

"She regrets now that she ever married Marc."
