During an interview with the U.K. radio station Capital FM, which airs Monday night, Gomez reveals that fellow Taylor Swift squad member Kendall Jenner is off the market.
"Taylor is not single, Gigi is not single, neither is Kendall," Gomez tells host Roman Kemp, according to Music-News.com. "I am the only single one!"
While the singer keeps quiet about who Jenner's boyfriend is, the model was most recently linked to One Direction crooner Harry Styles.
The pair spent New Year's together in the Caribbean, and shortly after, sister Khloé Kardashian revealed that Jenner and Styles were "dating."

"I don't know if they're like boyfriend-girlfriend. Nowadays, I don't know, people are weird with stuff. So I don't know their 'title,' Kardashian told Entertainment Tonight in January, using air quotes. "But I mean, they were in St. Barts together hanging out, so to me that's dating. I would call that dating."
The stars haven't been photographed together since, however, and Jenner has been busy traveling for Fashion Week gigs.

Gomez also opens up about her own life in the interview, discussing how things have changed since her first studio album Stars Dance.
"This is what I've always loved to do and I had so much to prove, I was in a point in my career where I was very motivated by the chaos that was around me," Gomez says. "There was a lot of noise – the world had an opinion on my life and it was a little invasive. I wanted to use that as motivation to write this album and to create something that was authentic and was real and genuine and me. Now I am a little bit more open."
