Taylor Swift and Calvin Harris 'in love'

TAYLOR Swift and Calvin Harris are "in love".

Things are already getting serious between the 'Shake It Off' hitmaker and the music producer, who have been dating for a few months.

A source told HollywoodLife.com: "They both are very into each other and are in love, and say it to each other quite often."

Meanwhile, a source previously claimed that the 25-year-old beauty will arrange to see Calvin whenever she can, even if it means flying thousands of miles and across continents.

The insider shared: "Whenever she has a break in her tour, she flies on her private jet to meet up with him. Taylor feels very safe and secure with Calvin so she usually doesn't have her bodyguard around if Calvin is over.

"Sometimes she will leave for a few hours and go on a hike with friends or go to a business meeting, but they always meet up again later in the day."

And when Taylor can't make it to Calvin, he is happy to be her "tour groupie".

Another source added: "Calvin is bending over backwards for her. He's fitting himself into her life completely and he's even promised to visit her as much as he can when she goes on the tour. They're making jokes about how he's going to be her tour groupie.

"But they will still have a lot of long distance to deal with and that part sucks, she knows that won't be easy. That's the only drama she's got with Calvin though; otherwise it's pretty much perfect."
