Cara Delevingne and her friend Sienna Miller land together at JFK Airport

They’ve been close friends for years.

And Cara Delevingne and Sienna Miller were reunited for a trip to the Big Apple on Thursday, as they arrived together at John F. Kennedy International Airport in New York City.

The 29-year-old model and actress, who have previously been sharing playful kisses at parties, wrapped up in a cozy black overcoat, while the 40-year-old Lost City Of Z star opted for a more casual brown sweater.

Although she’s best known for her haute couture looks, Cara proved herself to be a master of casual fashion with her traveling ensemble.

She paired the dark cashmere overcoat with a low-key cropped black sweater, which revealed a longer pale gray shirt popping out underneath. 

She contrasted the dark colors with black-and-white gingham pants, which were haphazardly tucked into her black combat boots.

The Suicide Squad actress wore several gold chains around her neck and carried a black Yves Saint Laurent tote bag slung over her shoulder, along with her guitar case, which she wore like a backpack.

Sienna looked toasty in a loose-fitting brown sweater with long sleeves that nearly swallowed up her hands, teamed with a grey T-shirt and baggy flared jeans.

The Layer Cake star completed her outfit with weathered white Nike high tops, and she didn’t appear to have carried any luggage out of the terminal.

Both stars were masked up to help slow the spread of the surging Omicron variant of the coronavirus, with Sienna opting for a surgical mask while Car wore a more heavy-duty respirator-style face covering.

As they left the airport, the two women were seen being led by a woman with a badge around her neck. 

It’s unclear if the two longtime friends had been traveling for work, or if they were just vacationing together.

Cara and Sienna have been inseparable in the past, and they’ve even been spotted in years past kissing at parties, though it’s not unusual for Cara to share public kisses with her female friends.

The Mail on Sunday reported from a source in 2014 that Sienna had become ‘relentless about wanting to spend time with Cara,’ and that their closeness — and public kisses — contributed to the end of Cara’s relationship with actress Michelle Rodriguez. 

A source also told MailOnline at the time: ‘Sienna is relentless about wanting to spend time with Cara. She seems a bit obsessed.

‘When Cara was dating US actress Michelle Rodriguez, Sienna was always getting involved and it caused an issue. She was always kissing Cara, which Michelle wasn’t keen on.’

More recently, Sienna has been linked to the businessman Archie Keswick, whom she was seen spending time with over the summer, though it’s unclear if they’re still together.

She had previously dated Lucas Zwirner throughout 2019 and 2020.

One of her most significant relationships was with Jude Law, whom she dated on and off from 2004 to 2011, which included a brief engagement early on.

She later dated the actor Tom Sturridge from 2011 to 2015, and the former couple share their nine-year-old daughter Marlowe, who didn’t appear to have traveled with Sienna.

Cara, who identifies as bisexual, was most recently in a relationship with Ashley Benson from 2018 until their 2020.

Cara recently debuted a tattoo she got matching Selena’s that showed a rose that was dripping blood.
