Taylor Swift may have split from boyfriend Calvin Harris just last month, but she's already moved on -- with sexy British star Tom Hiddleston!

The duo were seen walking along the beach near Swift's mansion in Watch Hill, Rhode Island, and not only were they spotted kissing, but they were snapping selfies with one another. That's how you KNOW it's serious!

"Taylor is hanging out with Tom. Nothing serious is going on but she is talking to him," a source tells E! News. "They have been out a few times she really enjoys his company. She is not looking to jump into anything this fast, but will take things as it goes nice and slowly."

While Taylor and Tom (can we call them Swiddleston?) seem like an odd couple, they kinda got their flirt on at the Met Gala in May, which is interesting. Swift, who attended the event solo, danced with Hiddleston, and video of their moves went viral on social media. Tom will be heading to Australia to shoot the latest installment of Thor, but Taylor doesn't seem too worried about that.

"Taylor is hanging out with her friends and keeping busy," a source added. "She wants to be single for a while and have a relaxing summer. She has some plans to travel this summer. Taylor has also been writing new music."

UH OH! New music? You know what that means...
