Leonardo Dicaprio partied with Rihanna at the Playboy Mansion.

The 40-year-old actor was spotted getting ''super steamy'' with the 'Rude Boy' hitmaker as they partied together on Saturday night (10.01.15) at designer Nikki Erwin's 30th birthday party.

The 'Wolf of Wall Street' star and the 26-year-old singer are said to have got ''hot and heavy'' and shared a kiss at the star studded bash, alongside Paris Hilton, Tom Hardy, Naomi Campbell, Pamela Anderson, Hilary Duff and Tobey Maguire.

However, a friend of Leonardo's has since told gossip website TMZ that this was not the case.

It is thought the actor - who is said to have split from his girlfriend Toni Garrn, 22, last month - was invited to the party by Nicki's producer boyfriend Chuck Pacheco.

It is also thought the pair carried on their night together at the same after party, along with 50 Cent.

Leonardo clearly enjoyed his evening and even photobombed supermodel Naomi and the 39-year-old rapper as the pair posed for a photo together.

50 Cent later posted the image onto his Instagram account.
