Britney Spears shares jaw-dropping bikini pic

There’s only one rule for getting "bikini ready": Put on a bikini. And, if you feel so inclined to flex in it afterward, more power to you.

We’re looking at you, Britney Spears.

The Piece of Me singer left Twitter in shambles on Sunday after sharing this poolside photograph, which showcases the fit body she’s sculpted during her residency at Planet Hollywood's Axis Theater in Las Vegas. "Just chilling," Britney captioned the app-breaking snap.

The famed singer previously gushed about her residency during an interview with USA TODAY. 

"It's in my blood to perform," Spears declared when the residency first began in 2013. "When I'm home and haven't done anything for a while, I get really itchy and nervous and weird-feeling. Performing is my therapy, to become different people onstage. It gives me confidence. I don't have that much confidence in myself. But when I'm onstage, it's my alter ego, and it kind of does adjust my personality."

And her figure.
