British actress Helen Mirren says it will be "very interesting" if the Duke and Duchess of Cambridge name their first child Diana.
Mirren, who won an Oscar for her lead role in 2006 film The Queen, claimed Kate would feel uneasy about the attention given to her pregnancy.
"That's weird isn't it, everyone knowing you're in labour," she said. "That must be so uncomfortable."
Mirren says it will be "great" if the baby is a girl because "we need more Queens in our life".
When asked what she thought about the name Diana for a girl - after William's mother - she replied: "I wonder if they'll go there. That would be interesting, wouldn't it? That would be very interesting.
"Her second name will be Elizabeth without a doubt."
Mirren said Queen Caroline "would work" - after Kate's mother Carole - while she also liked Charlotte and Victoria.
"It would be nice to have one of those ancient Anglo-Saxon names," she added.
