Rihanna joined her ex-boyfriend's (Chris Brown) arch nemesis on stage in the world's most romantic city, Paris.

Drake, who is currently on his Would You Like a Tour? tour, was joined by the 26 year-old singer during a performance at the Palais Omnisports de Paris-Bercy.

And despite the pair been in front of a sold-out crowd, they still got very close and personal with each other.

RiRi performed her hit track 'Pour It Up', as well as singing with Drake for their duet 'Take Care,' and during the pair's several seductive grazes into each other's eyes, it looked like a kiss was about to occur.

On one other occasion, Rihanna and Drake sent the French crowd into a frenzy after grinding on each other and getting extremely close, but this only lasted a matter of moments.

What a pair of teasers!

Several fan videos were uploaded online for the world to see their performances, but hopefully Chris Brown won't catch wind of them.

Both rappers haven't seen eye to eye since getting involved in a bloody brawl at the Wip nightclub in downtown Manhattan on June 13th 2012. The fight began after Drake allegedly sent Brown a note that read, ''I'm f**king the love of your life."

But the 'Started From The Bottom' rapper has recently stated that even though the Barbados beauty is the "ultimate fantasy" women, they are just strictly friends.

Drake is currently on the European leg of the 'Would You Like A Tour?'

Drake told Rolling Stone magazine, ''She's the ultimate fantasy. I mean, I think about it. Like, 'Man, that would be good.' We have fun together, she's cool and s**t. But we're just friends. That's my dog for life.''

All his female fans can breathe a sigh of relief as the Canadian native is still single and, although his womanising antics have calmed, the 27 year-old is still on the lookout for a girlfriend.

''I'm not after p***y like I was three years ago, when I was trying to make up for all the years when no girl would talk to me. But I haven't met somebody that makes everybody else not matter," he added.
