Kristen Stewart showed off her effortlessly chic style on Saturday night, as she attended a Q&A for her 2021 film Spencer at the Aero Theatre in Santa Monica.

The actress, 34, showed off her long legs in a pair of tiny knitted grey shorts, with a white lace underlay peeking out at the hem.

The Twilight star teamed the shorts with a matching button-up cardigan, left open over a plain white T-shirt, and added a silver chain necklace.

In an attempt to keep the cooler weather at bay, Kristen donned a pair of sheer black tights and white socks underneath her black high heels for an added preppy look.

Sweeping her hair up into an artfully tousled messy bun, she sported a light palette of makeup to accentuate her natural beauty.

Kristen was joined by her Spencer director, Pablo Lorrain, who looked smart in a black blazer and shirt, with a pair of green corduroy trousers.

She starred as the late Princess Diana in Spencer, which charted the beloved Royal's existential crisis at Sandringham during Christmas 1991, where she realised that her marriage to Prince Charles was beyond repair.

The film received rave reviews, including an impressive 83% on Rotten Tomatoes, with Kristen's performance garnering universal acclaim and bagging her her first Oscar nomination.

Missing from her side as she arrived at the film Q&A was Kristen's fiancée, fellow actress Dylan Meyer, 36.

The couple initially met on an undisclosed movie set in 2013, but did not become romantically involved until six years later.

In the summer of 2019, the pair reconnected at a mutual friend's birthday party and were later photographed kissing in New York City.

Kristen later gushed about falling for the screenwriter on The Howard Stern Show, saying: 'The day that I met her, it was like all bets were off.'

The couple got engaged in November 2021, with Kristen later revealing it was Dylan had popped the question.

Back in February, the Charlie's Angels star got candid about their relationship and explained how she knew she had found 'The One'.

She said: 'I found the right person because I can be so obsessive about what I do. And luckily my girlfriend, my partner, we are into the same s**t.

'We have taken the things that we’re spending our time on and interlocked them, and we’re so much f***ing smarter and stronger together. And you’re just like, "F**k", that is the best.'

While Kristen explained that she and Dylan bonded over growing up in Los Angeles and their similar personalities.

She admitted: 'We both felt like trolls as kids. We're like so similar but different. She's a writer. She's brilliant'.

Kristen publicly came out as bisexual in 2017 during an interview with The Guardian, after previously being linked to Twilight co-star Robert Pattinson, director Rupert Sanders, fashion blogger Sara Dinkin and model Stella Maxwell.

Back in January, she told Variety that her hit 2008 film Twilight has queer undertones and is 'such a gay movie.'

The actress said: 'I mean, Jesus Christ, Taylor (Lautner) and Rob and me, and it’s so hidden and not OK. 

'[Twilight is] all about oppression, about wanting what’s going to destroy you.That’s a very Gothic, gay inclination that I love.'
