Kylie Jenner and boyfriend Timothée Chalamet enjoyed a date night at game four of the NBA Playoffs.

The 27-year-old makeup mogul and 29-year-old award-winning actor — who made their red carpet debut last week at the 70th David Di Donatello Awards — sat courtside as they watched Chalamet’s beloved New York Knicks face off against the Boston Celtics.

At one point Kylie — who revealed a blemish earlier in the day — whispered something to Chalamet and they both flashed huge laughing smiles.

It comes as a source has revealed that the lovebirds are ‘practically living together.’

‘Kylie’s really happy and relieved they finally made their debut. It was time and she wanted to publicly support him and show how proud of him she is,’ someone close to the pair told Us Weekly. ‘She and Timothée have gotten really serious, and this was a big step.’

The insider also divulged, ‘They are practically living together at this point, as he stays at her house often when he is not working. He has been fully integrated into her life.’

And it was said that ‘everything is going really well’ between the A-listers.

‘She’s proud to stand by him and felt like it was the right time to share that part of their relationship,’ the source said about the duo’s first red carpet.

The person added: ‘They are in a really good place. He makes her feel calm and confident and it is a different relationship from what she has had in the past.’

On Monday night the mom-of-two went casual in a black tank top and black leather trousers. For his part, the Complete Unknown star layered a short-sleeved brown Knicks shirt over a long-sleeved black one.

He added black pants and an edgy studded belt while he and his girlfriend put on an animated display at the sporting event held at Madison Square Garden.

Kendall Jenner, 29, joined her sister and Chalamet at the intense game, and Kylie’s former BFF Jordyn Woods was in attendance as well.

The model was clad in a white tank top with spaghetti straps and black leather pants. She added a navy blue Knicks hat and let her wavy dark hair extensions flow freely underneath.

Woods, 27, had a falling out with Jenner in 2019 after a love triangle involved her, Kylie’s sister Khloe Kardashian, and Tristan Thompson.

It resulted in Jordyn moving out of Kylie’s guest house, and the two weren’t seen together for several years afterward.

They resurfaced as friends in July 2023 when they were spotted getting sushi.

In September 2024 they emerged together on social media, proving that their relationship is on the mend.

Footage recorded by a fan at Monday’s playoff game showed Woods dressed in all black as she greeted Jenner and Chalamet one by one.

One week ago Timothée watched a Knicks game from a tablet while his girlfriend stunned on the Met Gala red carpet.

She looked incredible as she arrived at the star-studded soiree in a custom Ferragamo gown. It boasted matching sheer opera gloves and a thigh-high slit that bared one of her long legs.

Chalamet’s night was spent watching the NBA playoffs, specifically ‘French NBA analysis,’ according to his Instagram Stories at the time.

He also appeared in a selfie with three friends, wearing a black hat and a gray hoodie over his head.

The reality TV star and Hollywood leading man reunited in Rome days later, walking the red carpet at the Di Donatello Awards.

They shared a sweet moment of PDA when the actor planted a kiss on the reality television personality before taking the stage to accept the David Speciale award.
