Ten months after splitting from One Direction's Harry Styles, the "I Knew You Were Trouble" singer has been spotted with another U.K. heartthrob – Romeo and Juliet's Douglas Booth.
"They hired the back room and were in there alone," a source tells PEOPLE of the duo's cozy night at The Holly Bush in London on Friday. "They looked very happy [and] were just smiling and laughing just like any other customers."
The duo possibly met through Swift's close friend Hailee Steinfeld, who starred opposite Booth, 21, in the latest installment of Shakespeare's classic love story about star-crossed lovers.
Swift, 23, showed up at the Los Angeles premiere's after party in September, where she was seen getting flirty with Booth.
The pair hung out with a group of friends (including Steinfeld), chatting and taking a series of fun photos in the photo booth.
No word yet on if the two are officially dating or are simply friends (reps for Swift and Booth did not respond to a request for comment), but sounds like a bit of quality time could go a long way with Booth.
"I've met some of the most beautiful women in the world, but they're not the most attractive women that I've met," he told PEOPLE in September. "Beauty comes from inside … I think it takes a little bit of getting to know someone to fall in love."
