Leonardo DiCaprio is taking full advantage of the wild happenings in Miami during Mercedes Benz Swim Week.

The “Wolf of Wall Street” actor has been spotted around town, partying with a “harem” of 25 female models, a source told FOX411. He spotted out with Kevin Connolly and Lucas Haas on Friday night at Adore in South Beach.

Then on Saturday, DiCaprio and his models headed back out to the WALL five-year anniversary party at the W South Beach. The New York Daily News reported his rumored girlfriend, Toni Garrn, was nowhere in sight.

“They took over huge portions of the clubs,” our spy told us, “having every bottle [available] -- champagne, vodka, whisky, tequila and beers.”

Our source said the group partied until the club closed and Leo left with the models.

Meanwhile, his ex-girlfriend Erin Heatherton was also in Miami enjoying the parties leading up to Swim Week.

She was spotted at The Delano in South Beach for an Ocean Drive Magazine party on Thursday night with fellow model Nina Agdal and the ladies were seen drinking Grey Goose cocktails and dancing, a spy told us.
