The Bajan songstress joined Drake at the Palais Omnisports de Paris-Bercy on Tuesday night (25 February) and the crowd were given a night to remember, with the two stars finally performing their hit single 'Take Care' live for the first time together.
Things got pretty raunchy on stage at one point too, as Canadian hit-maker Drake was spotted grinding up against RiRi while she sung.
It was certainly hard to ignore their chemistry!
Rihanna, 26, then took over and performed her sexy single 'Pour It Up', before later watching her pal from the audience and singing along to his popular track 'Started From The Bottom' along with the rest of his fans.
For the Paris show RiRi wore a pair of white tailored trousers, a white oversized jacket and a black bra top, which drew attention to her enviable abs.
Meanwhile, Drake appeared to match his fellow artist by also wearing all-white. We wonder if that was pre-planned or total coincidence?
The previous night Rihanna and Drake spent some quality time partying together at a local nightclub in the French capital and the 'Diamonds' singer has also been a special guest at a number of Drake's shows over the last few months - though yesterday was the first time she actually got on stage.
Last November, Drake also showed his support by attending a Rihanna concert and cheering her on from the back of the arena.
This super close friendship has now fuelled rumours that the pair have begun dating again, following a brief fling in 2009.
However, Drake dismissed this speculation in a recent interview and even implied that he and RiRi had never been an item, despite also admitting that the gorgeous songstress was a "fantasy".
Speaking to Rolling Stone recently, he said: "[Rihanna is] the ultimate fantasy. 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."
It's been a busy couple of weeks for Rihanna, since she only just wrapped up her 26th birthday celebrations in snowy Aspen.
She partied with friends in a luxury cabin and posed for numerous photos with her cake, as well as in her stylish snow gear.
