*”Being Mary Jane” star Gabrielle Union says she keeps fit these days thanks to her self–proclaimed “porn diet.”

On “Conan” Monday night (Jan. 20), Union said she recognized a few adult film stars who work out at her gym, and began to study their diet and exercise habits.

Asked if she makes a point of watching the porn stars working out on machines, she replied: “Yep, and I’ll be on the next one going, ‘You’re not getting off before me!’”

Union also admitted to following them to the gym’s juice bar to see what they order. Evidently, a vegan diet is the sustenance for porn’s best bodies.
