Taylor Swift has been on a date with Douglas Booth.

The "I Knew You Were Trouble" hitmaker - who has previously dated a string of high-profile stars including Harry Styles, Jake Gyllenhaal, John Mayer and Taylor Lautner - and the Romeo and Juliet actor spent time alone in The Holly Bush, a quiet pub in Hampstead, north London on Friday and even hired a room to ensure extra privacy.

"They hired the back room and were in there alone. They looked very happy [and] were smiling and laughing, just like any other customers," a source said.

Taylor, 23, was previously seen flirting with the 21-year-old British actor at the Romeo and Juliet afterparty in Los Angeles, where they hung out with a number of friends, including his co-star Hailee Steinfeld - a long-term friend of the singer - and took a series of pictures in a photo booth.

Douglas has previously said he can't fall in love with someone until he knows them well "I've met some of the most beautiful women in the world, but they're not the most attractive women that I've met. Beauty comes from inside ... I think it takes a little bit of getting to know someone to fall in love," he has previously said.
