Leonardo DiCaprio and Rihanna cozy at Playboy party

Rumors are swirling about the nature of Leonardo DiCaprio and Rihanna's relationship after the two were spotted partying twice together in recent weeks.

The 40-year-old Oscar nominee was seen partying with the 26-year-old Grammy winner at the Playboy Mansion on Saturday.

According to a source at TMZ the duo were getting cozy at the birthday bash, later winding up at the same after party.

Leonardo DiCaprio and Rihanna are said to have got 'hot and heavy' and 'super steamy' as they partied on Saturday night (10.01.15).

The 'Wolf of Wall Street' star - who is reported to have split from his girlfriend Toni Garrn last month - and the 'S&M' hitmaker were spotted at designer Nikki Erwin's 30th birthday party.

According to TMZ, a couple of eyewitnesses saw the pair share a sneaky kiss but a friend of Leonardo's has told the gossip website that was not the case.

The pair partied alongside several other stars including Paris Hilton, Tom Hardy, Naomi Campbell, Pamela Anderson, Hilary Duff and Tobey Maguire.

The 40-year-old actor is said to have been invited to the bash by Nikki's producer boyfriend Chuck Pacheco, and while it is not known whether or not he left with the 26-year-old stunner they are thought to have ended up at the same after-party along with rapper 50 Cent.

Leonardo looked to be having a good time at the after-party as he jokingly photobombed a picture of Naomi and the 39-year-old star, who uploaded the image on his Instagram account.

Last month, it was reported Leonardo had 'officially split' from his girlfriend Toni, 22, after dating on and off for two years.
