The teenager looked every bit the proud daughter as she pouted for pictures alongside her father – Game of Thrones actor Iain Glen, 64.
Snaps captured the pair at the opening night of The Importance of Being Earnest at the Noel Coward Theatre in London.
Mary wrapped up warm in an all-black ensemble, pairing a tweed-like jacket with a dark pair of jeans and chunky black boots.
The teenager, who describes herself on TikTok as a model under the Storm Models agency, struck a serious pose.
Iain opted for a slightly brighter get-up, pairing a bright blue button-up shirt with a cream overcoat and a pair of washed blue jeans.
The Scottish actor also chose a pair of chunky boots, completing his wintery outfit as the two took pictures outside the theatre.
The actor, known for his role Jorah Mormont in the hit HBO series, shares daughter Mary with his actress wife Charlotte Emmerson, 54.
They also share daughter Juliet, 13, and Iain also has a son called Finlay with ex-wife Susannah Harker. The pair divorced in 2004.
Iain’s no stranger to the red carpet after years in the industry, often taking his kids with him to premieres and theatre openings.
He’s also pretty open about his private and family life on Instagram, often sharing snaps with his 549,000 followers.

In 2022 he uploaded a throwback with a then very young Mary, showing the two on set in Spain while Iain filmed Game of Thrones.
“I’ll never forget the day,” he penned alongside the snap from 2014.
“My baby girl Mary came to the Bullring in Osuna to watch the Gladiatorial sequence when Ser Jorah fights for his life in front of his Queen.
“They made her up like her Papa and director David Nutter was so lovely looking after her all day. Mary even called ‘Action’ and ‘Cut!’”
Only last year Iain opened up about his youngest Juliet, who appears to be out of the spotlight apart from attending events with the family.
“She’s got a strange extrovert-introvert personality, which reminds me a little bit of myself when I was younger,” he told the Express.
“I would be painfully shy a lot of the time and then suddenly do something ridiculously ‘out there’ for attention.”
He explained a prank he’d play on his kids, which they all apparently love. “It’ll look like I really hurt myself in a humiliating way.
“I’ll be in a restaurant and my children will say, “Can you go to the toilet and accidentally fall over?'”
