The Duke of Cambridge is in his wife's good books after he "remembered" her 37th birthday - but he remained tight-lipped about the present.

William will reportedly join his wife and family during the evening to mark Middleton's big day.
"I just wanted to wish the Duchess of Cambridge a really happy 30th birthday", a leopard print-clad Kardashian says in a video message while holding up the shoe.

William, 36, will spend a major portion of Middleton's birthday visiting with London's Air Ambulance.
William also served almost five years as a helicopter pilot with the RAF's Search and Rescue Force. He also raised doubts over how she would cope with life in the Royal family.
The Duke and Duchess of Sussex first appearance of the year will be on January 14.
