Kylie Jenner unsurprisingly became the center of attention Tuesday at the "Wonka" A-list movie premiere and after-party in London ... despite being the plus one for boyfriend Timothée Chalamet.
Sources with knowledge tell us Kylie attended both the movie's premiere as well as the post-film bash at the Royal Festival Hall after she secretly touched down at Stansted Airport on her private jet.
Despite Kylie's attempts to keep a low profile at the party ... a source told Daily Mail she was the talk of the evening ... at one point heading to a private room behind a curtain to celebrate with Timothée.
"Wonka" -- hitting U.S. screens December 15 -- sees Timothée in the titular role ... tracing the character's origins from meeting his Oompa-Loompas to creating his iconic chocolate factory.
And it looks like "Wonka" will leave viewers craving more ... with early reviews hailing Timothée's portrayal as "whimsical" and "charming."
"I loooooooved #Wonka— everyone else did too right? It's so tender and entertaining with Colman a superb villain and Chalamet proving he can sing, too. Plus great songs and visuals. Take all of your kids," another wrote on X.
It's clearly a proud GF moment for Kylie, who has done her rounds supporting T since their romance came to light -- recently coming out to celebrate his 'SNL' hosting gig just weeks after he cheered her on at the Wall Street Journal Magazine 2023 Innovator Awards where she was honored for her designing talents.
Kylie and Timothée first sparked romance rumors in April ... and months later, they confirmed they were together with some hot and heavy PDA at Beyoncé's concert.
With a relationship that's been picture-perfect to date, it looks like the pair are set to wrap up the year on a sweet note, too ...
