Ariana Grande has finished working on her deeply “personal” fourth album, which sources are calling a masterpiece.

Insiders say that the pop princess played her new LP for executives at Republic Records and her manager Scooter Braun, reports TMZ. Grande corroborated that by posting a black-and-white photo of the session on Instagram Stories today (March 2).

A few details have already emerged about the album. For instance, sources say that Pharrell Williams and Max Martin split the production duties down the middle, while Ari was involved in writing every single song. Grande is still reportedly working on album art and visuals. No release date has been announced.

Skateboard P collaborated with Grande on last year’s “Heatstroke.” He also teased their work together last year, saying, “Ariana Grande’s album is amazing.”

The yet-to-be-named LP, which was previewed late last year, is set to follow 2016’s Dangerous Woman. It will also be the singer’s first album since the bombing at her Manchester concert and the One Love benefit show that she organized in honor of the victims.
