If I had three celebrities as sisters, these are the ones I'd choose:
AnnaSophia Robb: I love her. Obviously she's so pretty, but she's just one of my all time favorite celebrities! I love her style and she always seems to be smiling, my kind of girl :) I also love The Carrie Diaries. She just seems like a positive person, and who wouldn't want that kind of sister around?
Hayden Panettiere: I love the show Nashville, but I only started watching because Hayden was in it. Not only is she beautiful, she's also passionate about saving the oceans. She knows that swimming with dolphins means swimming in the ocean, not a trip to SeaWorld. She fights against captivity and the killing of dolphins and whales. We share a huge passion, so obviously we'd make great sisters... and maybe she could help me get over my fear of the ocean ;)
Taylor Swift: Well, we both have an addiction to Diet Coke.. She also has a huge beach house, so I'd totally be up for house sitting! I love Taylor, and she seems very genuine to me, and seems like fun, chill person to be around. It would also be nice to know the real stories of her love life :p
