Britney Spears Makes Major Announcement: The Abs Are BACK!

Weeks after Britney Spears scored a major victory in taking back her freedom from her (alleged) scumbag father, the soon-to-be-40-year-old mom made a major announcement Thursday that rocked the Instagram community.

They're BACK!

Spears, who turns 40 December 2, fired up her Instagram feed to announce, while spinning around her foyer to the sweet sounds of Gavin Rossdale belting out the Bush classic "Glycerine," that her abs were officially BACK.

"Well...for the love of God I finally see some definition in my abs," Spears announced. "It's finally nice to see some results!!!!"

Spears went on to say how Gwen Stefani invited her over one day to swim at the Stefani-Rossdale house to swim.

"Me and Gavin from Bush swam together...literally the coolest moment of my life," Britney wrote on Instagram.

Brit Brit has been on a major roll lately with the body content where it appeared her abs were back, but it wasn't confirmed confirmed until Spears made it Instagram official.

If you go back to September 30 when Spears posted nearly naked photos from a trip to the Pacific, it appeared the abs were back at that point, but that was to amateur eyes.

Speaking of those naked photos, Spears said this fall that being naked makes her feel "lighter" and this is her way of releasing the weight of the world that's been on her shoulders.

“I mean I don’t want anybody to see the big dimple on my ass but I feel like performing made me too self-conscious about my body and that’s not attractive,” she said on social media.

Now here we are, less than four weeks out from the Pacific trip and the hard work in the gym is paying off.

Britney Spears is back! The abs are back! It's go time!
