Selena Gomez has "Issues"—the good kind.

On Sunday (January 15), the pop star was snapped hanging out in the studio with Julia Michaels and Justin Tranter, the songwriting team behind a number of her Revival hits, where she danced and sang along to Michaels' own single, "Issues."

"When the people who changed your life create magic… I’m so happy for you guys – one of my favorite songs they have ever written," Gomez gushed in the caption of a video of her affectionately hugging Michaels, as the new song played in the background.

However, the "Kill 'Em With Kindness" singer wasn't the only one who shared a clip from the impromptu karaoke session.

Both Tranter and Republic Group president Charlie Walk also shared videos of Gomez hanging out in studio with them, and while the pop star spent her time promoting her friend's track, fans are wondering: What was Selena doing in the studio to begin with?

Fingers crossed she's working on her next album. In the meantime...
