PICS: Is Leonardo DiCaprio Dating 'Wolf Of Wall Street' Costar Margot Robbie?

Leonardo DiCaprio, 38, has been known for dating a revolving door of breathtakingly beautiful women, including actress Blake Lively, who is now married to former Sexiest Man Alive and Green Lantern costar Ryan Reynolds, model Bar Refaeli and, most recently, Victoria's Secret Angel Erin Heatherton, with whom The Great Gatsby star split in October after a 10-month relationship, reports news.com.au. Now rumors are flying that DiCaprio may have moved on to a romance with his The Wolf of Wall Street costar, Aussie actress Margot Robbie, 22, who had a stint in last year's desperately short-lived Pan Am with Christina Ricci, and the Australian series, Neighbours.

A witness reportedly spotted DiCaprio at Robbie's Manhattan apartment on Thursday night, and then again leaving on Friday morning. "He stayed overnight," a source told the New York Post. There have also been reports that Robbie, who plays DiCaprio's love interest, Naomi Lapaglia, in the upcoming Martin Scorsese The Wolf of Wall Street, joined DiCaprio for his 38th birthday party in Las Vegas last month. "There looks to be some strong chemistry between Leo and his leading lady," a source said at the time. "They spent a lot of time at the party together."

For now, however, DiCaprio's people are denying the rumors of a romance between him and Robbie. "That didn't happen," a rep of DiCaprio told the Post about the alleged overnight tryst. "Leo worked late and stayed home."

You can check out the chemistry between DiCaprio and Robbie when Scorsese's The Wolf of Wall Street, which also stars Jonah Hill, Matthew McConaughey, Jon Bernthal and Jon Favreau, hits theaters in 2013.

Before that, you can see DiCaprio in Quentin Tarantino's Django Unchained, opening Christmas Day, and Baz Luhrmann's remake of the classic F. Scott Fitzgerald novel, The Great Gatsby, hitting theaters on May 10, 2013.
