Joan Collins believes the demeanor of the duchess of Cambridge has been "flawless" ever since she married Prince William.
The 78-year-old veteran actor also admitted to be a huge fan of the 30-year-old royal, who married Prince William last April.
"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.
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.
