Selena Gomez is back in the studio, and the timing couldn’t be more perfect — ’cause, as of this week, Ariana Grande’s more relevant … on Instagram, anyway.

Selena was seen leaving a recording studio in L.A. Tuesday night, and ya gotta imagine she hopped into the booth and laid down some tracks. It’s been more than 3 years since she released a solo album, even if she’s been featured here and there with folks like Cardi B.

Funny enough … as Selena was in that studio, AG surpassed her fellow pop star in IG followers to become the most followed woman, if only barely. On Tuesday, Ariana reportedly hit 146,286,173 compared to Selena’s 146,267,801. Both ladies got nothin’ on Cristiano Ronaldo, though … who’s sitting pretty at 156M-plus followers.
