Hailey Baldwin has reportedly been partying hard ever since she turned 21 last month.

The American model celebrated her landmark birthday on November 22 and she's subsequently been spotted at numerous different nightclubs, including Story in Miami, where she witnessed DJ Marshmello's performance on Thursday (12.28.17).

A source told the New York Post newspaper's Page Six column: "She was in the DJ booth alongside Kygo."

Earlier the same evening, Hailey was also spotted at Komodo with some of her friends.

As well as partying hard, Hailey has also been romantically linked to Canadian singer-songwriter Shawn Mendes in recent weeks.

The high-profile duo were seen at Daniel Caesar's concert at The Danforth Music Hall in Toronto - Shawn's home town - earlier this month, and were said to be piling on the PDA.

Shawn and Hailey were holding hands and cuddling while watching the show, and she also appeared to be resting her back on his chest, according to an eyewitness.

Prior to that, the pair were reportedly spotted kissing into the early hours after the MTV European Music Awards.

Shawn - who won three awards, including Best Artist, and Best Song for 'There's Nothing Holdin' Me Back', at the event - was seen "French kissing" the model.

A source said at the time: "The place was packed with stars but Shawn only had eyes for Hailey.

"It clearly wasn't a one-time thing. They looked like they were seriously into each other. It was a very exclusive bash and Shawn and Hailey were really enjoying themselves, spending ages French kissing.

"They even posed for a photo with Rita Ora. It seemed like they wanted everyone to know they are an item."
