Tennis Star Anna Kournikova Will Not Return to NBC's THE BIGGEST LOSER

According to the Hollywood Reporter, tennis great Anna Kournikova, currently appearing as a trainer on Season 12 of NBC's THE BIGGEST LOSER, will not be returning to the show for another season. Kournikova replaced trainer Jillian Michael this season as one of the coaches of the popular weight loss competition. 
Contestants and members of the staff of the NBC show reportedly clashed with the professional athlete throughout the filming. Kournikova appeared to lack the sympathetic, soft qualities that Michael had brought to the competition and often scolded contestants when they complained about her harsh training techniques. According to one source involved in the show, the tennis great was "a nightmare".
In a statement to the Hollywood Reporter, Kournilova said,  "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."
