You can always count on Drake to wear his heart on his sleeve.

The 29-year-old rapper candidly gushed about Rihanna during her concert in Manchester, England, on Wednesday, after he joined her onstage for their duet, "Work."

"Shout out to the most beautiful, talented woman I've ever seen in my life," he told the crowd, before giving the 28-year-old "Sledgehammer" singer a huge hug. "She goes by the name of Rihanna ... I'm getting my heart broken."

After the show, the two raised even more eyebrows when they hit up a club together for the second night in a row. Drake and Rihanna were at Tape nightclub in London, England, just one night prior for Nicole Scherzinger's 38th birthday party on Tuesday, and literally partied until the sun came up. The pair was spotted separately exiting the establishment around 6 a.m. on Wednesday.

This, of course, isn't the first time the superstars have sparked romance rumors over the years. Most recently, the two have gotten pretty close during steamy performances of "Work," and even sweetly visited a cancer patient together at a hospital in March. Drake also fueled fan frenzy when he gave a shout-out to the singer in his song "Hype" off his latest album, Views, rapping, "They want to be on TV right next to me/You cannot be right here next to me. Don't you see RiRi right next to me?"

In March, a source close to Rihanna told ET that despite appearances, the two are "just friends."

"They love messing around with people," the source said. "They have a great friendship and definitely play the flirty game."

Most recently, Drake's been linked to 19-year-old model Hailey Baldwin. A source previously told ET that Drake and Hailey "hooked up" at the rapper's star-studded Memorial Day party, and the two were spotted having dinner together in Los Angeles last month before hitting up celeb hot spot The Nice Guy. In another sign that something's going on, the "Hotline Bling" rapper was spotted wearing Hailey's "H" necklace as he left the club.
