The Duchess left behind her Prince, but she showed the world something new.

On Wednesday night Kate Middleton made her first official solo appearance in London as the Duchess of Cambridge at a charity dinner for In Kind Direct at the Clarence House. Prince William's wife, 29, looked radiant in a floor length blue chiffon gown, with her styled hair half-up, half-down.

But underneath her beautiful 'do, Kate revealed an alarming three-inch long scar on the left side of her head, behind her temple. "The scar is related to a childhood operation," said a spokesman for the Duchess.

As a child, the Duchess had "a very serious operation," officials told the Daily Mail, but declined to detail the exact surgery or reason for treatment.

John Scurr, a London based surgeon, told the Daily Mail,"I really doubt it was any serious condition and I would say it is as a result of an arteriovenous malformation – a birthmark – being removed".
