On July 12, V magazine’s V114 Issue hit the newstands with Gigi Hadid gracing the edition’s cover story. Last night (July 19), the magazine and YouTube Music threw the model an intimate cocktail party with an impromptu performance by pop starlet Kim Petras.

Introduced by recent collaborator Charli XCX, Petras took the stage to perform four of her sugar-coated singles, “I Don’t Want It At All,” “Hillside Boys” “Heart to Break” and “Slow It Down” to the private, star-studded audience.

“To sing ‘I Don’t Want It At All,’ which is like the brattiest song about clothes, for V mag is gonna be lit,” she told Billboard backstage before the performance. “At one point, I was like, ‘Is this too bratty? Are people gonna think that I’m the worst person ever?’ But all these people who love fashion can totally relate.”

Petras is set to perform at the Billboard Hot 100 Fest on August 18 and 19 alongside headliners Halsey, Rae Sremmurd, DJ Snake and Future. However, for the rest of the month, she says, she’ll be juggling a busy rehearsal schedule in preparation for accompanying Troye Sivan on his upcoming The Bloom tour.

“We were looking at other tour offers at the same time and then the Troye thing came along and we were like, ‘This makes perfect sense,’” she recalled. “It’s my first tour ever, so I’m really excited to be on tour living that whole rock star life. I have no idea what it’s gonna be like, but I want it to be better than anything I’ve ever done.”

Fans can also expect more new music from the artist. On Twitter, Petras shared that she “can’t wait to release all these new songs,” though she seems in no rush to drop a complete album just yet.

“The singles will end up being on a cohesive record, but I’m still dropping songs one by one,” she said. “It’s a good way to keep staying relevant. I think that’s kind of the future. Ultimately, the album has a thread going through it so I can’t wait for people to hear it in full context.”
