Britney Spears' abs are ON ANOTHER LEVEL in Shape magazine.

Wanna know what we use for gym motivation? Oh, just Britney Spears' "I'm A Slave 4 U" video where she's sweating profusely and twerking her rock-hard abs. Wanna know what we're using NOW for going-to-the-gym motivation? Oh, just Britney's new June Shape magazine cover where her "Slave"-caliber abs are on full display. Only this is AFTER squeezing out two kids! It's UNREAL!

Decked in a super-revealing bathing suit that's either a one-piece, bikini, or both (Are you taking notes, Nicki Minaj?), Britney went into detail about her upcoming Vegas residency (YESSSSSSSS!) and workout routine (which we imagine isn't too far off from Justin Bieber's workout routine): "I'm doing 90 minutes of yoga twice a week in addition to a lot of cardio -- hour-long sessions three times a week with my trainer, Tony Martinez. The [Vegas] performances won't be simple -- they'll be a massive party from start to finish. And to pull this off, I have to be in top condition and running at full speed."

Wow, well, that routine is paying OFF, bb! Keep up the good work! Also, just know that today you've inspired us to swap our traditional mac & cheese + Ben & Jerry's lunch for some healthy crudités and water.
