I thought this is Sienna Miller’s sister but Wiki says that Marisa Miller is an American supermodel who was born on August 6, 1978. She is known for her many appearances in the Sports Illustrated Swimsuit Issues and Victoria’s Secret catalogs.

Well, if she is Sienna’s sis then I wouldn’t be surprised at all. They are both hot but I have to say that Marisa is the hotter one. I have a feeling Marisa’s fashion sense is way better than Sienna’s.
