Anna Kournikova Leaving 'Biggest Loser'

Anna Kournikova will not return for the next season of NBC’s weight loss series The Biggest Loser.

The 30-year-old tennis star told THR, “I enjoyed my time on the Biggest Loser ranch. Although I will not be returning as a full time trainer on season 13, I will always be a part of The Biggest Loser family and my commitment to bettering lives through health and fitness will continue.”

Anna took over the role as a trainer on the show after longtime Biggest Loser coach Jillian Michaels left the series.
