Mariah Carey and Nick Cannon may have kept their wedding plans secret, but now they are inviting all of their friends to a big summer wedding party in the Hamptons to celebrate their union. Page Six is reporting that Mariah Carey rented Stone Meadow Farm in East Hampton, L.I. for the small price of $125,000.

That kind of money gets them 10 bedrooms, 18,000 square feet, and 8 acres to play with. The party will reportedly be hosted by Def Jam chief L.A. Reid.

The kicker in the deal? If the Cannons really enjoy themselves, they have the option to buy the place, which is listed at $20 million.

And you wonder why Mariah is trying to get Nick Cannon on that upgrade plan?
