After spending three nights in a row together in London, Drake has fueled speculations of his romance with on/off lover Rihanna after he was spotted leaving her central London home on Friday morning (1 July), following a big night out. The One Dance singer kept a low profile in a fluffy, fur jacket as he left the building, pulling his coat's hood up over his head.

According to Mail Online, the 29-year-old singer made a speedy exit, as he kept his head bowed down.

The night before, Riri and Drake returned to the same building following a visit to the Chiltern Firehouse, the day after he reportedly told a Manchester crowd that he was falling for her.

IBTimes UK reported that Drake told the crowd at Manchester's Emirates Old Trafford stadium: "Shout out to the most beautiful, talented woman I've ever seen.

"She goes by the name of Rihanna," he went on to say. "I'm getting my heart broken over here."

The pair have enjoyed London's night life, as they partied at Tape nightclub until 5.30am on Tuesday, followed by Tramps nightclub until 4.30am on Wednesday, and now the Chiltern on Friday night.

They first sparked relationship rumours in 2010, but sources close to the stars claim it's "just for fun" this time around.

"They aren't seriously dating," an insider told E! News. "He still loves her and never stopped. Rihanna is the one that's been not wanting to settle down in the past. They are having fun spending time with each other. Their music together got them close again."

Speaking about her on/off lover earlier this year, Rihanna told Vogue: "Everything he does is so amazing. We would go to in the Caribbean and just dance and drink and smoke and flirt."
