Swift has also been linked to Matt Healey from the band The 1975, after he revealed the two exchanged phone numbers. Taylor and Karlie just happened to be at a concert for Matt when the photo above was taken.
"I met Taylor Swift, that was really nice,” the 25-year-old said during a recent radio interview. "We exchanged numbers. Let's see what happens. I mean bloody hell, what am I going to do? Go out with Taylor Swift? She's a sensation, I wouldn't say no."
