Los Angeles, California - Kylie Jenner and Timothée Chalamet are still raising eyebrows as the Khy founder attended the Oscars afterparty solo!

Those swirling Kimothée breakup rumors have persisted since the 26-year-old beauty mogul pulled up to Sunday's Vanity Fair Oscars afterparty alone.

Kylie stunned in a busty red Ludovic de Saint Sernin dress and partied at the event with her BFF Anastasia Karanikolaou, plus her sisters, Kim Kardashian and Kendall Jenner.

But why was the Wonka star absent from the yearly awards ceremony?

There could be a number of reasons why Timothée skipped the Oscars since he's just wrapped up his Dune 2 promo tour – though his costar Zendaya made an appearance as a presenter.

Also, the last time Kylie and Timtohée were seen together publicly was at this year's Golden Globes ceremony.

Recently, Kylie dodged questions about her relationship with the Oscar nominee during a chat with The New York Times.

"I just don't want to talk about personal things," she told the outlet.

Hopefully this breakup chatter gets cleared up soon!
