Lululemon has named Lewis Hamilton as a brand ambassador, collaborating on product innovation, social impact initiatives, and a new marketing direction.

Lewis Hamilton may have a joint-record seven Formula 1 titles to his name, but he suggested winning the championship with Ferrari would be the most important yet.
