Drake and Hailey Baldwin are dating "super casually".

A source told PEOPLE: "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 their date said: "They kept close to one another, but weren't super affectionate since they knew people were watching."

They reportedly first hooked up at Drake's Memorial Day bash at his Hidden Hills, where it has been claimed that police were called after a fight broke out.

There were a number of noise complaints about rapper's bash between 9pm and 10.30pm and video footage shows a group of women brawling.

TMZ reports that busloads of women were seen arriving at the Hidden Hills mansion and the party "got extremely rowdy as the day went on and several girl fights erupted".

Paramedics were also spotted at the scene but no injuries have been reported.

Hailey was previously linked to Justin Bieber, 22, but claimed that she didn't want to date a celebrity.

She said: "I don't want attention out of dating somebody. Texts started coming through, crazy phone calls ... it's hard to date somebody in this industry.

"You have to have really thick skin and be very strong. You have to focus on the person and nothing else. And you have to, as best you can, block out all the extra noise."

And Drake was most recently linked to his on/off love Rihanna, 28.
