Singer Selena Gomez told E! News at the Sundance Film Festival that she may “eventually” make a song with 26-year-old Taylor Swift, who she called her best friend. Gomez, who was recently rumored to be dating Justin Bieber again, had released an album in 2015 with hit songs like “Hands to Myself” and “Revival.”

Gomez was asked by E! News at the festival if she would make a song with Swift, with whom she’s has appeared in “Bad Blood.” She said: “Oh, I don't know. I mean, eventually, right?” adding: “She's my best friend. We'll see.” Although it was not a clear yes, E! News speculated that it was not a denial.

Last month, Gomez was heard in a song by Charlie Puth, named “We Don’t Talk Anymore,” which seemed to be a happy breakup song. The song is part of his album “Nine Track Mind,” which released Jan. 29, MTV reported.

“I met up with Selena, and she went through a very public relationship, on and off, and she could just relate to the song and the lyrical sentiment,” Puth told MTV in December, adding: “I was playing the song for her, and she just started singing the second verse. I got chills. I was like, ’Oh my gosh, that sounds so real. You need to sing on it.’ And she said yes.”
