Actor Leonardo DiCaprio celebrated his 38th birthday with a group of A-listers including Beyonce, Jay-Z, Robert De Niro and Cameron Diaz. But according to one report, his beautiful blonde film co-star Margot Robbie kept his attention at the Saturday night party.

Robbie, 22, may not be on the A-list celebrity radar but DiCaprio surely made her feel like she was. 

The actor's bash was held at The Darby in New York, according to The New York Post. 

DiCaprio, who just split with girlfriend Erin Heatherton, is in Manhattan filming the Martin Scorsese film "The Wolf of Wall Street," which also stars Robbie. According to the Daily Mail, they were joined by Jonah Hill, who also stars in the tale of Wall Street excess.

His birthday dinner was a multi-course meal of branzino with truffled crust, yellow sashimi, spinach truffle pizza appetizer and steak filet with truffles. According to reports by DJ Lino Meoli, "things got pretty crazy."

He told the Daily News that DiCaprio requested for some West Coast hip-hop songs when the DJ was playing golden oldies. "Leo was on the mic beat-boxing to 2 Chainz and had all his buddies up [on] stage," Meoli said.

According to The Mail, Robbie and DiCaprio have been spending an increasing amount of time together as they were also spotted at a party in Las Vegas. Margot, 22, has a background in long-running Australian soap opera, "Neighbours," and the axed television series "Pan Am."   

The Daily News reported that DiCaprio started off his night by hosting a TAG Hauer event at the American Museum of Natural History with Diaz for the New York Cares Hurricane Sandy Relief Fund. 

"The Wolf of Wall Street" will be released in 2013.
