Even though she possesses one of the most infamously svelte figures in reality television, Biggest Loser trainer Jillian Michaels will be leaving behind a huge pair of sneakers to fill when she departs from the show after a seven-year association with the show. It was previously announced that trainer/boxer Cara Castronuova and trainer/kickboxer Brett Hoebel would be added to the show next season alongside Jillian’s Biggest Loser trainer buddy Bob Harper, but it was revealed earlier today that professional tennis superstar (and uber babe) Ann Kournikova will also be joining the show as a trainer on The Ranch!

From X17online:

X17online can report exclusively that Anna Kournikova will lend her athletic training skills to The Biggest Loser next season as the show’s trainer. NBC will make the formal announcement on the season finale next Tuesday.

Russian-born Kournikova made her professional tennis debut at the ripe young age of 14 and has had a very successful career on the court, especially as a doubles player alongside partner Martina Hingis. But Kournikova is perhaps better known for something other than her tennis skills – looking damn fine. She and her amazing features have graced the pages of the Sports Illustrated Swimsuit Issue, FHM, Maxim and numerous other mens magazines resulting in her being one of the top ten searched athletes in the world for the last decade.

Anna is no Biggest Loser virgin either, as she made an appearance in 2010 during the tennis workout challenge.
