The 'Blank Space' hitmaker has been jet-setting across the world with her new boyfriend and has reportedly told friends it is getting serious between them.

A source told E! News: "She is having a blast travelling with him. He is very romantic and attentive towards her. He is extremely charming. He also makes sure she feels safe wherever they go together.

"She is on cloud nine and really enjoying this quality time they are spending. She texted her close friends and said, 'I think I am in love and I never felt this way before!'"

Meanwhile, the 26-year-old singer - who split from Calvin Harris less than a month ago - and 'The Night Manager' star, 35, spent the weekend at the beach in Suffolk, England with his family.

Of their romance and Taylor's split from Calvin, a source said previously: "Tom checks off a lot of boxes for Taylor. He's hot, smart, talented, British, 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.

"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 and has also been writing new music."
