Selena Gomez is newly single, but that doesn't mean she's moping around.
Justin Bieber's ex is having a blast in the studio! The 20-year-old singer tweeted several pictures of herself Sunday, Monday and Tuesday enjoying herself in between working on her music.
In one shot, Taylor Swift's BFF crosses her arms and flashes double peace signs above her head. Curiously enough, she appears to be wearing a hat with the Stratford Cullitons logo. (If you'll recall, the Biebs got a tattoo of the Canadian hockey team's mascot on his back in honor of his grandfather earlier this month.)
