American singer/songwriter Taylor Swift and Scottish singer/DJ Calvin Harris are reportedly getting serious about their relationship.

According to Daily Star, the 25-year-old Shake It Off singer will meet the 31-year-old DJ's parents when she arrives in the UK on 23 June, as a part of her 1989 tour.

"Calvin has hired the private dining room in the Ubiquitous Chip restaurant for the meeting. Taylor's mum Andrea is also hoping to fly over between treatments for her cancer," a source said.

Rumours that Rita Ora's former boyfriend and Swift are dating started in March, and the two were pictured shopping in Nashville, dressed similarly.

Later, the two were spotted at a Kenny Chesney concert, getting cosy in the audience. Which followed up with Swift kissing Harris during the Billboard Music Awards 2015, held at the MGM Grand Arena in Las Vegas on 17 May.

Meanwhile, it was previously revealed that Ellie Goulding played cupid for the pair and encouraged them to go on a date.

"I did play matchmaker, that's true," she said. "Calvin is a really great mate and he's so fantastic, and Taylor is such a cool person who I love. I thought, 'They're both really awesome and both really tall, they'll be brilliant together'."
