The S&M star was seen arriving at Kings of Leon frontman star Caleb Followill’s birthday party at the Sunset Marquis in West Hollywood making a very low-key arrival in a white t-shirt and jeans.
For his part, Titanic star Leonardo wore a flat cap and cuddled up to one of his BFFs, Kevin Connolly from Entourage, as he strolled through the hotel’s lobby.
It is worth noting that Rihanna, 26, and Leo weren’t pictured together, but their latest outing will no doubt fuel the speculation that these two are more than friends.
In fact, resident Playmate Carly Lauren Tweeted to say: “Just saw Leo and Rihanna making out while Pour It Up was playing.”
Over the festive period, the couple were partying together at La Plage Club during their Caribbean break.
They also attended the same VVIP parties, including one at a pal’s private apartment.
“By this weekend, a lot of people were already talking about them being an item.”
The pair have been spending more and more time together over the past few years and they also attended two parties together last year, including Rihanna’s afterparty following the Met Gala, and a club night with Katy Perry.
Rihanna has previously dated controversial singer Chris Brown, 25, Canadian rapper Drake, 28, and baseball player Matt Kemp, 30.
Traditionally Leo favors Victoria’s Secret models, having hooked up with Naomi Campbell, Gisele Bündchen, Bar Refaeli, Erin Heatherton and Toni Garn.
But Leo has been known to spread his love far and wide, also rumored to have romanced Clare Danes, Demi Moore, Paris Hilton and Blake Lively. Source
