Anna Kournikova Is On And Now Off "The Biggest Loser"

I don't know if you are a fan of NBC's "The Biggest Loser" but my family definitely is. My 11-year-old, my husband and I are addicted to this show. I don't know if that's a good thing but isn't the first step towards recovery admitting that we have this problem?
Anyway, I keep meaning to post about one of the new trainers in Season 12 - Anna Kournikova! If you remember, last season, she appeared on the show to put the contestants through a round of Cardio Tennis. I posted about that here - Anna Kournikova Takes Cardio Tennis To The Biggest Losers. This season, they brought her back as a full-fledged trainer! I think the idea was for her to try and replace the apparently irreplaceable Jillian Michaels. I say irreplaceable because even though Season 12 isn't finished, it has already been announced that Anna will not be returning for Season 13.
At first, I was skeptical of Anna's ability to train anybody to do anything, let alone help these incredibly obese people through the emotional miasma of their weight loss. I mean let's get serious - Anna Kournikova has never been overweight in her life. She has more in common with a super model than with a fatty. But over the course of the season, she really seemed to get into the concept of the show - providing these people with both physical fitness training as well as psychological guidance. I thought she ultimately did a great job and was a nice contrast to the other two male trainers. And I liked that she worked tennis into her training program every chance she got.
Apparently, however, the show was not "the right fit" for her and so she won't be returning next season. Too bad - now we'll have to meet some new female (I'm sure) trainer who won't be a good substitute for Anna or for Jillian. Oh well.
My family and I will miss you Anna and I'm sure a lot of other viewers will too. Good luck finding something to do as lucrative "The Biggest Loser." I'm pretty sure its not World Team Tennis.
