Kylie Jenner and Timothée Chalamet sparked split rumours following their recent appearance at the Oscars. Multiple sources revealed a slew of possible reasons for the couple's decision to go their separate ways. However, one major cause for the couple's alleged split is said to be 'jealousy.'

Shortly after last week's Academy Awards, a photo of Jenner hugging a mystery man circulated online. The snap led fans to think that the reality TV star had already moved on from Chalamet. However, the photo seems questionable because the caption referenced the Grammys, not the Oscars.

Photo With an Unidentified Man

The photo in question shows Jenner wearing an all-black ensemble, reportedly standing outside the Hard Rock Hotel in Florida. The unidentified man she met up with is wearing a navy blue coat, and the two exchanged a tight hug in public.

'Following her reported breakup with Timothée Chalamet, Kylie Jenner was spotted with an unidentified man at the Hard Rock Hotel in Florida. According to sources, Kylie was reportedly upset with Timothée after he was seen socialising with people she disapproves of at a Grammy after-party,' the X user wrote.

Fans of Jenner and Chalamet were surprised to see the reality TV star with another man so soon. One said they could not believe how quickly Jenner had moved on, while another asked Grok to confirm if the photo was AI-generated. The AI replied that it wasn't.

'It appears to be a genuine candid photo, not AI-generated or manipulated. No text, logos, or identifiable public figures jump out, so without the specific claim or backstory attached to it, I can't confirm "truth" or provide full context. What's the angle here?' Grok's response read.

Possible Reasons for the Couple's Split

Rumours about the couple's split had been circulating even before the Oscars. In fact, one parody account on X claimed that Jenner and Chalamet agreed to attend the Oscars together even though they had already split, as the couple did not want the public to speculate further on their relationship.

Other insiders are convinced that the breakup happened because Chalamet did not win an Oscar. Several others also thought that Jenner called it quits because she was jealous of some of his co-stars. Earlier this year, a source claimed that Jenner was not a big fan of Chalamet's intimate scenes with Gwyneth Paltrow in 'Marty Supreme.'

Some fans also accused Jenner of texting her baby daddy, Travis Scott, while she was at the Oscars with Chalamet. Others claimed that it was Chalamet who ended things with Jenner, and that the ''Keeping Up With the Kardashians'' star is begging him to get back together.

'This has happened before, but she talked him into getting back together. She is crazy about him, so that could well happen again,' a source said.

The Couple is Still Together

A lip-reader seemingly debunked the breakup allegations by saying that Chalamet asked Jenner for a 'big cuddle' after the awards show wrapped up. Jenner also liked one of Chalamet's posts about his movie, and insiders claimed this was her way of denying all the split rumours going around. However, Jenner and Chalamet have not responded directly to any of the allegations surrounding their relationship.
