Dailymail.co.uk : In 2007, Marc Jacobs walked onto the catwalk of his own fashion show to reveal the dramatic transformation he had made to his body.
The famed fashion designer lost weight and toned up by eating only vegan food and training two hours a day, seven days a week.
And today he showed that he’s still keeping in great shape, especially at 48-years-old, by flaunting his incredibly ripped beach body as he walked along the St. Barts beach with his equally muscular ex-fiance Lorenzo Martone.
