I don't watch reality shows, but I'm pretty sure that Monica Seles was in that show a couple of years ago.
Was she grunting to the music 

good one Sid. as much as I like Seles, and yeah she is a great champion, she started all that screaming, grunting whatever you called it sh!t. then all other girls followed. the only difference is that, I think it came to Sales naturally. I don't think she did in on purpose. However, I can't watch the WTA any more, it's like EEEEEEEEEEAAAAAAAAAAAAAAAAAH, I really don't get it. After Seles, these girls (Sharapova, Azarenka etc.) were trained to shriek and the whole tour is ... well, we all know... I will watch a WTA match on a good day when I fell in a good mood, but I simply really have hard time focusing on the match when girls are simply screaming so hard ...
