Rosa Acosta has been dedicated to putting on mass and achieving the perfectly toned, yet thick physique, but she revealed that a new project is requiring her to slim down. The stunning model and fitness enthusiast posted a photo on her Instagram page and told followers that she was "saying bye bye to all my thickness." 

"Say bye bye to all my thickness.  I'm working on a major project and I have to drop all the weight it took me so long to gain. Currently at 150 34d-25-39 and each one of my tights measures 24 ( that's two bad bishes waist lol ) I will go down to 130-135 the healthy way - Will keep you guys posted and soon will let you know about my special project as well." 

Her followers were obviously upset, considering the majority of Rosa's Instagram posts are sexy photos of her showing off her incredible curves.
