Tennis legend Novak Djokovic and his wife, Jelena, have been together for over 20 years. They met in high school in Serbia and tied the knot in 2014. Ahead of the new Prime Video documentary 'Novak Djokovic: The Wolf in Winter,' coming out on August 20, the athlete shared with People the three key ingredients for a lasting marriage: communication, honesty, and transparency.
"You have to communicate when something is not feeling right. The more you keep it inside, the more the monster grows," he explained.
With frequent time away due to his demanding tennis career, Djokovic credits Jelena for supporting their kids, Stefan, 12, and Tara, eight.
