Kylie Jenner and Timothée Chalamet Pack On the PDA at US Open Date

Kylie Jenner and Timothée Chalamet have done a total 180! They spent the first few months of their rumored relationship keeping things private, it was hard to know if it was fact or fiction, and they're now throwing caution to the wind. That's if their most recent appearance at the US Open is anything to go by.

Jenner and Chalamet were spotted among the many celebrities attending the US Open together on Sept. 10, and they weren't shy about public displays of affection. In photos snapped of the couple at the sporting event, when they weren't snacking on chicken tenders, they were laying on the PDA, putting their arms around each other, taking photos, and kissing.

Jenner and Chalamet's appearance at the US Open comes about a week after the pair were spotted for the first time together at Beyonce's "Renaissance" concert in LA on Sept. 4, where they also made no effort to hide their affection for one another. Their concert date night officially put dating speculation that had been raging since April to rest. While fans still don't have explicit confirmation that the pair are officially a couple, it's safe to say that their romance is very much alive.
