Tom Brady and Alix Earle had an "instant connection"

A source told Us Weekly: "Alix and Tom were together the entire night on New Year's Eve partying at a party hosted by Palm Tree Crew in St. Barths. They met through mutual friends who were also in St. Barths and had an instant connection. There was a lot of chemistry between them."

The source added that Tom was "hesitant" about being seen together in public "but didn't want to leave her side", while "Alix was really into hanging out" with Tom but isn't looking for "anything serious".

The insider added: "It's nothing serious between her and Tom, but they were together laughing, dancing and partying, enjoying themselves.

"Alix is in a phase of saying yes to fun experiences and not overthinking anything.

"She's just having fun right now and letting loose. She has been in great spirits while on vacation and seems happy and ready to have fun again."

Alix is currently single following her recent split from Braxton Berrios.

She told her TikTok fans: "Braxton and I are no longer together. We have been doing long distance since, basically, June and we haven't got to see each other that often. It's just been really difficult for me."

Following their night out together, Tom - who was previously married to model Gisele Bundchen - posted a cryptic quote on Instagram.

He shared: "People are not beautiful for how they look or speak. They're beautiful for how they love, care and treat others."
