The 'Feel So Close' hitmaker is reportedly shocked his ex-girlfriend - who he split from around two weeks ago - has already been spotted kissing Tom Hiddleston.

A source said: "Calvin was surprised to see the photos and that she had moved on so quickly. That was fast! It was surprising to him but he just wants to move on. He's a really good guy."

And the 'Shake It Off' hitmaker is said to have a very close bond with 'The Night Manager' star over their worldwide fame.

An insider added to Us Weekly magazine: "Tom checks off a lot of boxes. He's hot, smart, talented, British, blond, everything she's into. What's not to like? She's going with it and why shouldn't she?

"They have been bonding over the industry, their childhoods, where they are from. It's the getting-to-know-you phase. Taylor is just happy to have the time to meet someone new and move on from Calvin."

Meanwhile, it was previously claimed that Taylor knew her split from Calvin was "for the best".

A source said: "Taylor is not sad anymore about the breakup. She knows it was for the best. They are not on bad terms. They have communicated since the breakup, but getting back together is something that's not in the cards for either of them. Taylor is hanging out with her friends and keeping busy. She has some plans to travel this summer. Taylor has also been writing new music."

Taylor was spotted smooching Tom on Misquamicut beach near her home in Watch Hill, Rhode Island earlier this week.

An insider said of their meeting: "They were all over each other - hugging and kissing - even though there were 20 people coming and going on the beach. They looked like any young couple madly in love without a care in the world."
