He’s never without arm candy for very long, and Leonardo DiCaprio has selected his latest main squeeze. She’s none other than Margot Robbie!

The ex-“Neighbours” babe met her “Catch Me If You Can” beau on the set of their new flick “The Wolf of Wall Street,” and things are going swimmingly for the fledgling pair.

Last week, Leo “stayed overnight” at Margot’s New York City apartment after partying together for DiCaprio’s 38th birthday back in November.

An eyewitness told press, "There looks to be some strong chemistry between Leo and his leading lady. They spent a lot of time at the party together."
