Work B—ch! Britney Spears spent some adorable mother-son time with her boys Jayden and Sean but we couldn’t stop looking at her rockin’ bod!

The 33-year-old wore a tiny purple bikini to match her dip-dyed locks while on holiday in Hawaii on July 24.

She showed off her serious rock hard abs, showing her recent weight loss since filming her “Pretty Girls” video with Iggy Azalea when not-so-flattering photos of her tummy leaked.

OK! exclusively reported that Britney dropped 12 pounds in the past few months, because she was “horrified” to see photos from the music video shoot.

“It was a big wake-up call and she’s been religiously getting back into shape,” the source told OK!

According to the insider, Brit amped up her ab workout and even banned her beloved junk food to shed the excess pounds.
