Drake and Serena Williams: Are They Hooking Up Again? [PHOTOS]

Drake and Serena Williams ingnited countless romance rumors as they have been spotted kissing in the clubhouse after her victory against Victoria Azarenka in the Wimbledon quarter final.

The 28-year-old rapper has been unattached for a while, but those romance rumors are starting again as the 33-year-old tennis pro even embraced him after her press conference on Friday.

Although the two have yet to say anything about their speculated relationship, something has definitely been going on between them.

“Publicly she says they’re just friends but Drake has been by Serena’s side throughout the tournament,” an insider told The Sun. “And when they’ve been away from the public and relaxed, it’s been pretty obvious they’re together.”

A celebratory kiss after a win is pretty suspicious and it definitely caused some talk within Serena’s camp.

"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," the source said. "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."

Drake was at Center Court on Friday as Williams lifted the Wimbledon trophy for the sixth time. Along with a picture of the winner holding up the trophy, Drake shared on Instagram: "Showtime Champ. A big plate for all that food you ate at Wimbledon!"

Serena and Drake were linked together in 2011, but the romance quickly fizzled out, and Drake was spotted on a date with model Dollicia Bryan in 2012.

Serena's ex-boyfriend, rapper Common, opened up last year about his relationship with Serena on the Rickey Smiley Morning Show and revealed a possible romance between Serena and Drake.

"Me and Serena was together. We broke up," he said. "I don't know specifically her and Drake, it felt like obviously something was going on [after we broke up], I ain't dwell on it too much.
