Mark was looking sharp in a blue jacket, matching jeans, and snazzy Gucci sneakers.

The hit-maker kept the party going throughout the night as he hit the DJ booth.

The party comes weeks after Mark confirmed his engagement to Grace, the daughter of Meryl Streep.

The couple first sparked betrothal rumors in May when Grace was seen wearing a dazzling diamond on her ring finger in London.

Confessing that he’d popped the question, Mark told The FADER Uncovered podcast last month: ‘I got engaged last weekend.’

He went on to recall his first kiss with his fiancée, admitting it was a ‘corny’ experience.

Mark quipped: ‘There’s a plaque for that somewhere. There’s a first kiss, very corny Hallmark first kiss plaque.

Earlier this year, it was claimed that Mark and Grace were an item after they were first linked in September during a cosy dinner date in New York.
