It was the ultimate meeting of minds and hard abs this weekend in Miami: Olympic swimmer Ryan Lochte and “Jersey Shore” star Mike “The Situation” Sorrentino partied together at LIV at the Fontainebleau on Saturday. Spies told us the pair were introduced by mutual friends and spent the entire night together laughing. At 5 a.m., Lochte and Sorrentino — who this year finished a stint in rehab and drank bottled water all night, according to sources — left the club through the back door with a gaggle of women.
