‘Nah we good.

‘Stop jinxing the Knicks!!

HOW DO WE FEEL ABOUT THIS, KNICK FANS? I PERSONALLY DON’T APPROVE.’

Timothee, who skipped the Met Gala last week to watch a Knicks game with his pals, watched eagerly from the sidelines as his team beat the Celtics 121-113.

He was clearly delighted with the victory as he was spotted jumping around in celebration with director Spike Lee.

At one point Kylie whispered something to Timothee while watching the game and they both flashed huge laughing smiles, looking totally smitten. 

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

A source close to the couple spoke about their recent debut and told Us Weekly: ‘Kylie’s really happy and relieved they finally made their debut. 

The couple were seen in LA last month supporting Kylie's beloved Lakers - but the star appears to have switched teams now

‘It was time and she wanted to publicly support him and show how proud of him she is. 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.

The outing came days after Kylie and Timothee made their red carpet debut as a couple at a glitzy awards ceremony in Rome last week.

‘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.’
