The duo, who has claimed repeatedly they're just friends, grinded on each other on stage while performing their song "Take Care."
Rihanna and Drake's performance went down at the Palais Omnisports de Paris-Bercy Tuesday evening during Drake's sold-out show, where the pop star showed up for a surprise appearance.
And surprise she did.
Rihanna strutted on stage in all-white suit, headed Drake's way for their duet and twerked in front of him as they performed it, with fans cheering loudly from the audience.
While it seemed liked there was a bit of sexual tension brewing between the music stars during their steamy set though, both have said there is nothing more to their relationship than friendship.
Still, Drake did call Rihanna the "ultimate fantasy" in a recent interview with Rolling Stone just a couple of weeks ago.
"I mean, I think about it. Like, 'Man, that would be good.' We have fun together, she's cool and sh-t. But we're just friends. That's my dog for life," he continued.
What do you think? Are Rihanna and Drake just friends? Or something more?
