The Hollywood actress famous for her work in "Buffy the Vampire Slayer," has compared the bodies of the sisters and explained how society reacts towards their looks.

It seems that even popular people can't get enough talking about Kate Middleton. The "Suburban Girl" actress dropped her two cents on what she thinks about the Duchess of Cambridge and her sister's physique. In a an interview for iVillage, the actress told what she thought of the newly-inducted royal and her sister.

"It seems like people are worried that (Catherine's) stressed. I feel like 10 years ago, it would have been like, 'Oh, she looks incredible.' Whereas you look at her sister, who has such a fabulously athletic body­ -- I mean, a real athlete's body -- and I think there's this movement now, where more women, finally, want to look like that." said Gellar in a post by Celebs Gather.

Since the Royal Wedding last April, the Middleton sisters have been under the eye of the public non-stop. Unlike Catherine who is currently being groomed for her future public appearances and how to deal with the governments from around the globe, Pippa is enjoying a socialite life without the restrictions of being in the royal family.

Just recently, Pippa was spotted at a Temperley London fashion show wearing a short dress, a big mistake for someone sitting at the front row. On the other hand, Catherine has been dubbed as the "new fashion queen" by many designers who bow at her elegant choice of clothes and ensembles. Some of Catherine's favorite designers are Issa London, Reiss, and Alexander McQueen.
