The Duchess of Cambridge is more resilient than she appears and is completely smitten with her husband Prince William, a friend has claimed.
As William prepares to turn 40 on Tuesday (June 21) and becomes a more established and confident heir apparent, the friend revealed that it is his relationship with Kate that keeps him calm, grounded and ready to do his royal duty.
Despite being quietly spoken and reserved in the public eye, the friend insisted that Kate is "tougher than she is often given credit for" and William relies on his wife as the pressures of royal life are set to only increase for the pair.
