Kylie Jenner's birthday tainted by Timothée Chalamet's brutal snub amid split rumours

Timothée Chalamet marked Kylie Jenner’s 28th birthday on Saturday with a cryptic social media post, fuelling ongoing speculation that the pair have ended their relationship.

The Call Me By Your Name actor, 29, shared an image from a historic boxing match showing Muhammad Ali celebrating victory, overlaid with the words “Dream Big” in red, handwritten-style lettering instead of wishing his girlfriend a happy 28th birthday.

The American-French actors cryptic post has now added fuel to fire as fans fear that Kylie and Timothee have officially called it a day. It comes after Kourtney Kardashian's fans pointed out a deadly parenting mistake as the star took emergency action.

Timothée and Kylie were first linked in April 2023 after reports surfaced that they had been spending time together.

They made their first public appearance as a couple in September that year at Beyoncé’s Renaissance World Tour in Los Angeles, where they were photographed kissing and laughing together in the VIP section.

Since then, the couple have kept their relationship relatively low-key, occasionally being photographed on outings but avoiding public commentary about one another.

Over the past month, fans have noted the absence of any new images of the pair together, with Kylie also posting a series of Instagram Stories featuring melancholy song lyrics which have further fuelled rumours of a split.

The timing and content of Timothée's post on Kylie's birthday left many fans baffled as some believe the “Dream Big” message may be a subtle reference to his upcoming film Marty Supreme, due for release on Christmas Day.

According to IMDb, the drama follows “Marty Mauser, a young man with a dream no one respects, [who] goes to hell and back in pursuit of greatness.”

While Timothée decided to publicly snub Kylie's birthday, her famous family marked her big day with their annual warm and emotional posts.

Kylie's mum, Kris Jenner shared a carousel of throwback images of her youngest daughter as she wrote: “Happy birthday to my baby girl!! You are truly beautiful inside and out… You are so smart, strong, creative, loving, kind, funny, and always so supportive… I love you beyond measure… Mommy.”

Meanwhile, Kendall Jenner shared childhood photos alongside the caption “my little lady forever,” to which Kylie responded: “kendall jenner !!!!”

Khloé Kardashian posted a montage of photos and a video of Kylie holding a cake at what appeared to be a Saturday night birthday gathering. Khloe, 41, captioned it: "Forever and then some, I love you to the moon and back. Happy birthday my girl… My soulmate sister… I love you beyond words, always and forever. With all my heart, Your second mommy, Khloé.”

Kourtney Kardashian posted: "Tinker Bell! May you shine forever my little goose sister.” While Kim wrote: “Kylie’s day! Happy Birthday to the goat."

The birthday girl also shared her own post, uploading childhood snaps including one where she sits proudly with her first bicycle, captioning it: “happy birthday to meeee.”
