It looks like Drake and Serena Williams have fired up their romance a notch. The pair have been caught on camera kissing in public after what appears to be another date night.

The footage, which was uploaded on Instagram by a Drake fan account, @ovodrakevideos, shows the Young Money rapper kissing the tennis star outside a building before seeing her to her SUV. The clip comes weeks after photos emerged of Williams, 33, and Drake, 28, piling on the PDA during a romantic dinner date in Cincinnati on 23 August after weeks of speculation about their relationship.

This wasn't the first time the two have been romantically linked. In 2014, there were reports that there was something going on between the two. In August an insider gushed about the pair's rekindled romance telling E! News: "Things are heating up with the duo and all of Serena's friends approve of the pair."

The source also claimed that the Yolo hitmaker was "a true gentleman and is very supportive" of Williams' career and busy schedule adding: "They are both private people when it comes to their personal lives."

Although it was originally thought that the romance had sparked a feud between the Young Money rapper and Williams' former beau, Common, he recently insisted that there was no bad blood.

"Serena is a friend of mine, as long as she's happy I'm good," the Suicide Squad actor told TMZ. "That's my friend, we dated, that's been done a long time ago. She's doing super well on the tennis, she's incredible so as long as she's happy I'm good."

But despite Common giving his blessing, friends have voiced their concern she will end up hurt. One pal said: "Even Serena's team have been talking about it in the clubhouse to a few people they trust. She has been incredibly focused on her title bid. But if she's had a quiet moment she's spent it with Drake, even going to watch his Wireless set and having dinners in London."

Television host Wendy Williams also cautioned the sports star, citing Drake's "player" status."I'm worried Serena is choosing the wrong guy. Drake is younger than she is [he's 28, she's 33] and a bit of a ladies man," she said in her September contribution to Life & Style, via Classicalite. "If I were her, I'd consider Drake a snack instead of the main course. Move on before you get hurt, girl!"
