Rihanna and Leonardo DiCaprio fueled relationship rumors when they were seen hanging out together over the past few weeks. These rumors heated up when the actor supposedly threw the Barbadian beauty a party for her 27th birthday last Friday in Los Angeles.

"There were balloons that spelled out her name set up," a source told US Magazine.

The party reportedly took place in Beverly Hills and lasted past 4 a.m. There were about 75 people in attendance at the huge birthday bash. Some of the A-list stars that attended the party included Naomi Campbell, Beyoncé, Jay Z, and Mick Jagger.

Sources told Urban Islandz that Rihanna and DiCaprio kept their distance throughout the night but were flirty when they were near one another.

"There were definitely some chemistry but they clearly were trying to keep things low key," a source claimed.

Rumors of the Rihanna and DiCaprio's hookup surfaced at the start of the year. The pair reportedly hung out during New Year's Eve and Valentine's Day. They were also reportedly seen making out at a recent birthday party held at the playboy mansion.

Despite the flirting and romance between the two, DiCaprio reportedly wants to continue living the bachelor lifestyle and will not commit to the singer. New rumors are claiming that DiCaprio was seen flirting with newly single "Fifty Shades of Grey" actress, Dakota Johnson.

An insider told Life & Style that DiCaprio "put his arm around Dakota and led her into the grand ballroom. He told her, 'Let's go look at all the celebrities,;" at the SNL 40th after party held at The Plaza Hotel.

The source added, "Dakota looked like she was trying to play it cool, but you could tell she was thrilled to have his attention...Out of everyone he socialized with, Leo seemed to be the happiest when he was with Dakota. As they walked away, Leo took the lead and guided her through the crowd, and a small smile spread across her face."

Rihanna and DiCaprio have not commented on these rumors at all.
