Rick Ross is officially moving to Miami Beach’s secluded Star Island … closing on a $35 million home smack in the middle of the celebrity hotbed.

The rapper closed the deal Monday on his latest real estate splash … a 6-bedroom, 9-bathroom mansion with all the bells and whistles.

Rick’s new 40,000-square-foot pad is decked out with a heated pool, entertainment room, summer kitchen and plaza deck terraces opening up to the beautiful waterfront, plus a 40-foot dock.

The boss’ new neighbors are just as impressive … we’re talking huge stars like Jennifer Lopez, Shaquille O’Neal and Diddy.

As we first reported … Rick has been eyeing the place since July, and he’s planning a major renovation to fit the palace to his liking.

So, the $35 million Rick just plunked down to buy the place is just the start of his investment.

The Star Island mansion adds to Rick’s already impressive real estate portfolio … he’s already got one home in Texas, two in Georgia and another in Florida.

Boss moves!!!
