The 26-year-old actress, who has her own range of handbags, does not wish to change anything in Catherine, also known as Kate Middleton before her marriage to Prince William, reports contactmusic.com.
"I think she's perfect. I like her style. She always looks put together, cute and pretty. I definitely wouldn't change her," Barton said. Known for being part of movies like 'Notting Hill' and 'The Sixth Sense', Barton said she enjoyed watching Catherine cheer teams in the Olympics and that she is a great role model.
"I think she's a much more positive role model than most we see in ads and magazines. During the Olympics, it's given people so many more positive role models and she's been one of the existing ones we look up to who's positive and healthy and cool," she said.
