Leo DiCaprio goes wild at the Art Basel Party after a fitting speech the day before

Leonardo DiCaprio one moment Mr. Environment, and the next moment, Hollywood’s favorite party boy – a feat he proved again this weekend at Art Basel in Miami.

The actor was present again on Friday for a big party in the Magic City, where Wayne And Cynthia Boich hosted a bunch of stars at their private mansion… including Leo and his girlfriend, Vittoria Cerettiwho at one point smoked next to her husband in the evening.

Leo was in party mode, putting on his signature black cap and puffing out whatever he was chugging – while Vittoria hit her vape. Quite a change from how he looked on Thursday night, when he took center stage for a speech at an environmental event.

At the Re:Wild meeting where Leo spoke, he was in eco mode… where he was as polished as possible and looked very sharp. 24 hours later he’s letting it all hang out!

Anyway, Friday’s mansion party was a who’s-who of stars… Tom Brady there was, but that was also true Sean Penn — who even hugged it out with Leo at one point — as seen here in a photo obtained by TMZ.

Sean was also mingling with the people inside… hot on the heels of a performance by Snoop Dogg, who had performed for the rich and famous crowd not long before. Speaking of SD…he was also chatting in the crowd after doing his thing on the mic, which was great.

Snoop sang a few of his songs… and he definitely had everyone dancing along.

It’s just the last Art Basel stop for Leo, who is been in town since earlier this week. Something tells us we’ll be seeing a lot more of him on Sunday too.
