Rihanna and Leonardo DiCaprio pictured together for the first time as they make ‘debut’ at her birthday party

The stars were seen getting close as she was surrounded by her friends and family to celebrate her big day.

TMZ just obtained the first photos of Leonardo DiCaprio and Rihanna pictured together since news hit town that the A-listers are dating. The actor is pictured standing next to the singer at her birthday party two weeks ago.  

Rihanna and Leo DiCaprio should be a perfect match -- neither's into settling down with one person for too long -- but now that they're banging ... one of them is way more committed than the other.

We got pics of RiRi and Leo getting cozy recently at her birthday party -- which he helped organize -- and sources at the bash tell us one thing was clear ... Rihanna's the clingy one.

We're told Leo is affectionate enough -- they engaged in plenty of PDA -- but he could barely get a moment to himself. As one source put it, "she's the baddest bitch in the party, but she's following him everywhere."

We're told they've been hooking up for about 3 months, but it's still not exclusive -- more like they're each other's first choice. Not that anyone's crying for either of them. #LeoProblems

Insiders have claimed that the Wolf of Wall Street star, who reportedly helped organise the star-studded bash, was kissing Rihanna at multimillionaire James Goldstein’s mansion and the party was still going at 4am on the Sunday morning.
“They were kissing and dancing together,” a source told Us Weekly.

Also celebrating Rihanna’s birthday were Beyonce and Jay Z, Robert Pattinson, Mick Jagger, Jim Carrey and Bill Murray.
Bill Murray is EVERYWHERE these days.
Insiders at the party have claimed that while Rihanna is one of the hottest stars in the world, she was doing all the chasing.
A source told TMZ: "She's the baddest b****h in the party, but she's following him everywhere."
Rio (yes we are calling them that) did nothing to stop the rumour mill over whether they are dating, as they were spotted arriving at the same nightclub in the early hours of the morning on Valentine’s Day.
The S&M star was seen arriving at Wolf of Wall Street star Leo’s home at 1am before they separately went to Up and Down, a nearby nightclub.
