Taylor Swift and Jake Gyllenhaal have met one another's families.

The 'Love Story' singer - who was first romantically linked with the 'Love and Other Drugs' star five weeks ago - cancelled Thanksgiving plans with her parents to spend last week's holiday with her rumoured boyfriend's relatives, before bringing the actor back to Nashville with her.

A source said: "Jake invited her to New York for Thanksgiving. It wasn't planned in advance, but she said, 'Why not? I can do it, and I'm going.' Her parents weren't thrilled, but she explained to them that she gets to see them all the time and wasn't able to spend much time with Jake during the publicity Madness.

"She loves his family and he loves hers."

Though Taylor, 20, was a guest of 30-year-old Jake's family - including his mother Naomi Foner, sister Maggie Gyllenhaal, her husband Peter Sarsgaard and their four-year-old daughter Ramona - she was more than happy to help out with cooking and household chores.

The source told Us Weekly magazine: "There was no diva behaviour. She pitched in to cook and to clear the dishes. She also seemed very interested in the family and asked them a lot of questions about themselves."
