This is pretty old (november of last year) but I just found it yesterday so I thought I'd let other people know who might have missed it too.
The sisters were on Oprah and you can't watch the show but she does this thing now called "after the show" where you can watch clips on the internet of what they talk about when the show is done.
I watched some really good ones of the different celebreties and this one of the williams sisters was really great. They are two very inspiring women.
The aftershow was great. I loved it when Oprah asked about Venus' personal life. I think she was addressing a rumor that Venus was married? The look on Oracene's face was priceless!!
