Kylie Jenner already has a photo of her and Timothée Chalamet as her phone background

There are plenty of markers that a relationship is progressing in a positive way.

You might soft launch on Instagram with a subtle picture of your new boo's hand.

Things could escalate with the eventual hard launch and tag.

You might start introducing them to your friends and family.

Pet names might also come into the fold.

At one point in the many paparazzi snaps, her lockscreen flashed on and it displayed a selfie of the happy couple being all cute and intimate.

Some people reacting to the update thought it was lovely she was already saving pictures of them together on her phone.

However, others suspected it was a little too staged and reckon this could be the work of a manufactured relationship.

The two had sparked dating rumors for months, however no one had ever really seen them together.

They finally revealed they were a couple when they attended Beyoncé's Renaissance World Tour in Los Angeles and were spotted cuddling and kissing.

Fans were shocked as they speculated that it was just Hollywood whispers that they were an item.

But here they were, locking lips and partying together.

Even the official US Open X account wanted to shout about their appearance, sharing a video of the pair in the Cadillac Suite.

Jenner and Chalamet sat together to watch the men’s single final match between Novak Djokovic and Daniil Medvedev in New York City on September 10.

The stars were practically dressed as spies in all black and matching black sunglasses as they wrapped their arms around eachother and cosied up.

But they couldn’t have looked any less undercover as they sat in a sea of (much more colourfully dressed) celebrities including Laverne Cox, Molly Ringwald, and Ebon Moss-Bachrach.
