Kylie Jenner reportedly jetted into London with beau Timothée Chalamet to secretly support the actor at the world premiere of Wonka.

Joining her boyfriend at The Royal Festival Hall on Tuesday, The Kardashians star apparently steered clear of the star-studded red carpet, which was walked by a whole host of famous faces including Hugh Grant, Olivia Colman and Rowan Atkinson.

Insiders say she somehow managed to dodge snappers as she sat down to watch her partner star in the role famously played by Gene Wilder in 1971 and Johnny Depp in 2005. Kylie also attended the film's glitzy afterparty in the capital, per PEOPLE.

Speaking to the US magazine on the red carpet, Timothée revealed the "challenge" of the role was to "live and love the tone of it". He explained: "I realized everything I've worked on [has had a] grounded seriousness to it, and here I had to loosen up and play, kind of like I did in high school, but I hadn't done in 10 years or something."

He added: "That was the learning curve. But once it was in full swing, then it felt like we were cookin'." Although Kylie wasn't on the carpet, it isn't the first time she's shown up to support her man, recently watching him host Saturday Night Live in New York City earlier this month, as well as attending a Beyoncé concert together in September.

Only recently a source revealed the pair's relationship is "fun and uncomplicated". They told PEOPLE: "He makes Kylie happy. He has his own life and understands that Kylie needs to prioritize her kids," said the source. "He is charming, very loving and protective of Kylie. She likes that he is a private guy."

Relationship expert Louella Alderson says their recent public displays of support are a sure sign the couple feel ready to commit, as well as clearly value each other’s interests and very successful careers. "Attending each other's work-related events can be seen as a sign of commitment and support in a relationship," describes Alderson, who is also the co-founder of the dating app So Syncd.

She told The Mirror: "Their public support of each other could also mean that they are becoming more comfortable being seen in public as a couple, which can be a significant step for any relationship. It's possible that they have had conversations about their commitment to their partnership and decided to take it to the next level by supporting each other at events."

The pair reportedly first met at the beginning of the year, shortly after Jenner split from her long-term on-off boyfriend Travis Scott, who is the father of her daughter, Stormi, and son, Aire. Romance rumours between them began to emerge in early April as sources said the duo were seen getting close at Coachella. Rumours hit a fever pitch when one of the reality star's (many) Range Rovers was photographed outside Chalamet's Beverly Hills home later in the month.

Despite packing on the PDAs, they are yet to officially attend an event together or walk a red carpet as a couple, which Alderson says is likely to be because neither wants the media attention their relationship would receive to outshine each other's work achievements. "Timothée hosting SNL and Kylie's WSJ Innovator Award were significant events in their respective careers. It's likely they wanted people to focus on their accomplishments rather than their relationship."
