The I'm Real hitmaker partnered with BodyLab to bring a new revolutionary lifestyle brand designed for the health and fitness efforts of women.
She said: "In all of my work, my music, my films, my book, my foundation, I always strive to inspire women to be the best and happiest versions of themselves, Jennifer said in a statement.
"I joined the BodyLab family not only because of their commitment to creating great health and fitness products for women, by women, but also because of their approach to the holistic lifestyle.
"It's not a solution-in-a-bottle. It's not a fad diet. It's part of a health regimen that makes your metabolism work as hard as you do. It's a way to love your body."See more pics below
