Major side boob—or just boob boob!

Britney Spears hit the streets of Westlake Village, Calif., on Wednesday, Sept. 2, rocking quite the revealing workout ensemble.

The pop princess, 33, who's been busy jetting back and forth to Las Vegas for her hugely successful Piece of Me show, exited the local gym sporting a white tank top with deeply cut arm openings, putting a generous portion of her bubblegum-hued sports bra on full display. She also wore plaid shorts, neon sneakers, and tortoiseshell sunglasses.

That same day, Spears took to Instagram to share an empowering message with her massive fan base. She re-grammed a photo of a lion, first posted by Jennifer Lopez, with this message: "A lion doesn't have to prove that it's a threat. You already know what the lion is capable of."

Of course, the workout ensemble is hardly Spears' first boob-baring look—even this past week! The "Pretty Girls" singer attended the MTV VMAs 2015 on Sunday, Aug. 30, wearing a plunging LaBourjoisie dress, complete with cutouts, sheer paneling, and a very high hemline.
