Australian Open, Pam Shriver kept talking about Alisa Kleybanova's weight?

During the match with Justine Henin and Alisa Klebanova, Pam Shriver kept talking about Alisa's weight and how she could probably play even better if she lost 5-10 pounds. I find that kind of offensive. I don't remember what else she said, but she constantly kept criticizing her weight.
