Rihanna parties with on/off love Drake

Rihanna and Drake have sparked speculation that they are back together.

The on/off couple – who recently collaborated on Rihanna’s song ‘Work’ – were spotted partying at the Nice Guy in Los Angeles over the weekend but took care to avoid being photographed together.

Drake has previously called Rihanna, 28, "the ultimate fantasy".

He said: "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 s**t. But we’re just friends. That’s my dog for life."

Drake said in 2011 Rihanna had unintentionally broken his heart with their on/off relationship, which came in the wake of her split from singer Chris Brown.

He said: ”At the time it hurt, but she didn’t mean to. I’ll never put that on her. I was hurt because I slowly started to see what it was. I guess I thought it was more.”

Meanwhile, their night out together is sure to come as a surprise to Hailey Baldwin, who is reportedly "casually dating" the 29-year-old rapper after they "hooked up" over Memorial Day weekend.

A source said: "Drake and Hailey are dating super casually, but he is really into her. They met through mutual friends and are taking things slow."

Witnesses who spotted them on a recent dinner date said: "They kept close to one another, but weren’t super affectionate since they knew people were watching."
