On Monday, Feb 24, Drake and Rihanna were spotted together again at the Sioxiante Dix Neuf nightclub in Paris. Drizzy was helping the club celebrate its first birthday and sources told E! that Rih stuck close to him while he took over the DJ booth.

In a recent interview with Rolling Stone, Drake opened up about his relationship with Rihanna but insisted that the two were just friends. Drake and Rihanna were romantically linked a few years back.

"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 sh*t. But we're just friends," he said. "That's my dog for life."

For right now, Drake said he's single.

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