Leonardo DiCaprio and Cameron Diaz Hung Out with Royalty Last Night

at 11:20 am | By

With the Cannes Film Festival (and its parties) winding down, Leonardo DiCaprio headed east over the weekend.

The dapper actor joined Cameron Diaz and Prince Albert II of Monaco in Monte Carlo for 2013 Monaco Grand Prix Party, hosted by TAG Heuer.

DiCaprio, 38, skipped the tie and stayed casual in a dark grey suit while his Gangs of New York co-star stunned in a form-fitting white dress.

Diaz, 40, recently flew in from New York City, where she’s been hard at work with Kate Upton, Leslie Mann and Nikolaj Coster-Waldau on the set of The Other Woman.

The Monaco Grand Prix commenced on Sunday morning.
