This is what 5-day workouts during the week and a strict diet will get you!
One of the reasons this photo was taken (beyond wanting to show the world that bod!) is that her buddy Stella McCartney wanted an impromptu swimsuit model — And Gwynnie was the perfect gal to model her faux snakeskin two-piece.
Along with the age-and-gravity defying pic (above), Stella wrote this on her Instagram:
‘Sexy lady in Stella swimwear! Summer never stop! x Stella.’
Looking fab, Gwyn!
