“FourFiveSeconds” singer Rihanna reportedly celebrated her 27th birthday with Oscar-nominee Leonardo DiCaprio. The R&B star celebrated at businessman Jim Goldstein's famed home in Los Angeles Friday, People magazine reported.

There are mixed reports about how the duo interacted with each other. They were flirtatious, but did not look like a couple, People reported. "They weren't couple-y but they would flirt and dance, so definitely a little magic there," a source said. "They were definitely flirty and dancing, but not over the top." 

But E! News wrote there was much more PDA -- or public displays of affection -- between them. RiRi and DiCaprio, 40, were seen touching, kissing and dancing together, a source told E! News. Both celebrities are “having fun” and not taking their alleged relationship seriously.

They were first linked in January getting cozy at the Playboy Mansion, but said they were “just friends” at the time, E! News reported.

Rihanna’s birthday was a star-studded event. Attendees included Mick Jagger, Russell Simmons, Paris Hilton, Nicki Hilton, Beyoncé, Jay Z, Bill Murray, Jim Carrey and Naomi Campbell.

Rihanna took to Instagram to send a message to her mother: "27 years ago, my mother gave birth to her very first child at the tender age of 27! Life is never a piece of birthday cake, but I feel special that I was chosen by my Father in Heaven to make it here!"

The singer just released her newest song, “FourFiveSeconds,” recorded with Kanye West and Paul McCartney. It was confirmed Monday that she and West will embark on a worldwide tour, Rolling Stone reported. The tour will simply be called “Kanye & Rihanna” and will kick off in Estonia on July 25.
