Sir David Frost: 'Diana would approve of Kate'

Sir David Frost has suggested that Princess Diana would have approved of Kate Middleton as her son William's bride.

During an interview on Piers Morgan Tonight, the journalist, who was a close friend of Diana, surmised that the late princess would have been overjoyed to attend the couple's nuptials.

"I think that she would be thrilled with the choice [William's] made [for a bride]," Frost asserted. "She would inevitably, in the circumstances... while being thrilled, be full of the most marvellously irreverent jokes."

Forst went on to express his belief that Middleton fully grasps the rigours that come with marrying into Britain's royal family.

He explained: "I've only met Kate once really, but I think that she's got great style. She's beautiful… And she took to the royal lifestyle with William very, very immediately. I would think she'll be a star."

Prince William and his fiancée are to marry tomorrow in London's Westminster Abbey. An official programme for the ceremony was released earlier today.

It's also been reported that Ellie Goulding has been asked to perform her cover version of Sir Elton John's 'Your Song' at the couple's wedding reception.
