The Duchess of Cambridge conducted her first solo engagement as a royal on Wednesday and had a mark visible on her left temple -- a scar, NOT hair extensions.
The Daily Mail first reported the mark was evidence of hair extensions, but are now saying it is a scar from a childhood surgery.
A spokesman for the Duchess at St James's Palace confirmed that it was the result of surgery as a young child. "The scar related to a childhood operation."
The palace declined to discuss what kind of operation, but royal sources say it was "a very serious operation."
Prince William could not attend the event at Clarence House due to a trip to Riyadh to offer condolences to the Saudi royal family following the death of the Saudi Prince, Sultan bin Abdul-Aziz Al Saud, who passed away last week in New York at the age of 80.
