Austin Mahone may be famous in his own right, but Taylor Swift is apparently the coolest celebrity in his phone. During a new interview, Mahone confessed to having the Mean singer's phone number.

"I've got a couple cool [numbers]," Mahone said while in London. "I've got Taylor Swift, that's probably the coolest. I was on tour with her, so I got her number from tour. She doesn't give it out to anyone."

Mahone opened up for Swift in 2013 during her sold-out Red tour.

In November 2013, Mahone had said he learned a lot from just watching Swift on tour. "It's been amazing. I've learned so many things from watching her perform and work the crowd," he told Life & Style. "She's super talented."

Another talented person Mahone loves is rapper Drake. Mahone has been pretty open about wanting to collaborate with the hit maker. "I'd say Drake was one of the coolest people [I met]," Mahone said. "I like Drake. He's a nice guy. I just told him, 'Yo man. Let's do a track together.' And he was like 'I'm in. just let me know.'"

Mahone may have to wait a little bit for that track since the 18-year-old is currently on an international tour with such stops as Paris. Mahone also just released his newest album, an EP called The Secret. "The vibe is kind of *NSYNC- Backstreet Boys kind of feel, but more EDM to it," he said, "guess kind of like a mixture of both. It sounds like one of my singles What about Love, really high energy and make people just want to get up and dance. Of course, I have some slow songs on there as well. It's cool."
