Suki Waterhouse looks chic in oversized mac as she party hops at NYFW with mystery man... as rumours swirl about her Diego Luna romance

Rumours of a reignited romance between Suki Waterhouse and Mexican actor Diego Luna have been swirling since January.

And now the British beauty has sparked fresh intrigue after she was spotted leaving the New York Fashion Week party with a mystery man.

Clad in a camel-coloured trench coat over a black jumpsuit, the model-turned-actress looked effortlessly chic as she slipped out the Pat McGrath Unlimited Make-up Collection launch party.

The fresh-faced star opted for minimal make-up with just a slick of black eyeliner which accentuated her brown eyes while her hair fell in loose waves.

Her dark-haired companion also went for a casual look, sporting a jeans and hoodie.

It was a busy night for the Love, Rosie star, who was also spotted at the Tom Ford's NYFW Spring Summer 2018 catwalk show earlier in the evening.

The star looked almost unrecognisable as she seduced cameras with her long glossy locks while posing in a knee-grazing frock.

She complemented her new glossy 'do as she slipped into a sensational LBD which featured sultry mesh side panels.

Highlighting her lean limbs, the saucy leather number exhibited her lithe frame while it skimmed her slender thighs and pert posterior as she stood in her black patent stilettos. 

Suki has been linked to Mexican actor Diego Luna since January, when they were seen looking cosy during a sun-soaked break in Mexico.

After months of laying low, Suki was then seen spending a week in the Big Apple with the Rogue One actor in June, reigniting rumours of a romance. 

However, the pair have never confirmed their relationship status. 

Previously, Suki enjoyed a two-year romance with The Hangover star Bradley Cooper but the former flames parted ways in 2015.

At the time, a source told E! News: 'They both want different things right now.

'She loves Bradley and he loves her but she's so young and wants to concentrate on her acting career before becoming a mum.'

Bradley has since gone on to welcome his first child with Victoria's Secret model Irina Shayk - a daughter Lea, born in March this year.
