Leonardo DiCaprio and Rihanna are back in the dating rumor mill again after they were spotted together in Paris on Sunday. The pair reportedly got intimate at the L'Etoile nightclub and were photographed sharing passionate kisses.

An eyewitness told The Sun that Rihanna and DiCaprio acted like they didn't care who were watching them. The rumored couple reportedly showed extreme PDA and were oblivious of the other people inside the club.

"Rihanna and Leo were really going for it. They were passionately snogging and didn't seem to care if anyone saw. They were using tongues so there was no mistaking it for a friendly smooch," the source said.

Rihanna was accompanied by model friend Cara Delevingne at the nightclub where it's believed they partied until dawn.

However, sources for TMZ denied anything sexual happened between Rihanna and DiCaprio at the club. They only ran into each other while at the French capital. The "Diamonds" singer saw DiCaprio and gave him a kiss on the cheek.

The sources claimed the photographers caught their friendly exchange. However, their photo was taken in such a bad angle that it made it look like Rihanna and DiCaprio were kissing lips-to-lips.

Another source likewise denied that the rumored couple kissed at the L'Etoile nightclub. The source told Mirror UK that Rihanna and DiCaprio just so happened to see each other at the club. "The Revenant" star was hanging out with his friends and Rihanna came with Delevingne.

The 27-year-old singer only approached DiCaprio's table to give him a kiss on the cheek and congratulate him for his Golden Globes win. The actor and Rihanna didn't hang out together at the club, according to the insider. Instead, she and Delevingne left together separately.

The pair also didn't agree to meet up in Paris. According to Mirror UK, DiCaprio was in the "City of Love" to promote "The Revenant." Rihanna, on the other hand, is said to be filming a new movie called "Valerian" in the French capital.

As for those dating rumors, the insider told Mirror UK that DiCaprio and Rihanna are just friends. TMZ's sources likewise said the actor is very much single at the moment after a recent split from Victoria's Secret model Kelly Rohrbach.

This is not the first time that Rihanna and DiCaprio were rumored to be dating. They grabbed dating headlines early in 2015 after they were spotted hanging out together several times. DiCaprio was also seen at Rihanna's 27th birthday party.
