Taylor Swift's ex, DJ Calvin Harris is believed to be livid that the singer met her current beau, actor Tom Hiddleston's parents just two weeks into their relationship.

The 32-year-old reportedly finds it "comical," and he's more "bewildered and astonished" than angry that the Shake It Off hitmaker never met his mom and dad while they were together, a source says. The two dated for 15 months.

Swift and Hiddleston have taken off on their first vacation together to Italy, after meeting each other's parents. On Monday, they were spotted enjoying a day of sightseeing at the Colosseum together, walking hand-in-hand.

A gossip website claimed that Taylor texted her close friends and said, 'I think I am in love and I never felt this way before!'

The couple was first spotted getting close at the Met Ball in May, while she was still dating Harris.
