Well, that was quick. Michael Lohan is up and at ‘em after reportedly suffering a heart attack less than two weeks ago — and, surprise, surprise, he’s stirring up some gossip in the Hamptons.

We hear Lindsay’s dad, 49, has set up house in Southampton with girlfriend Kate Major (ex-flame to his ex-bud Jon Gosselin) to work on his latest project: a reality TV show.

“In July, eight to 10 celebrities will go on a ‘Tour for Charity,’?” he excitedly dished about his new gig, which he claims is being optioned by a variety of networks.

There’s an added twist in Lohan’s show: He has cast not only Major but her latest bestie, Hailey Glassman. As in … Jon Gosselin’s other ex-girlfriend.

“The two have really bonded over their hate for Jon,” confirms an insider close to Major.

This reality gig isn’t the only thing Michael is working on — he insists he’s still trying to reconcile with LiLo, too.
