Joan Collins believes the demeanor of the duchess of Cambridge has been 'flawless' ever since she married Prince William.

"I very much like Catherine. What do we call her now? The Duchess of Cambridge sounds so old! Can't we just call her Princess Catherine as they do in America? She has not put a foot wrong," Contactmusic quoted her as saying.
"She even looks like a princess. I think Prince William has done a great job and taught her what to expect. She is flawless in everything, her clothes, her smile, her attitude," she said.
The former 'Dynasty' star was also a huge fan of William's mother, the late Princess Diana, and was devastated when she died in 1997.
"Diana had a tough time. She wasn't strong enough to survive what was happening to her. I loved her," she added.
