Prince William's Night Out---Prince William enjoys a night out: The Duke and Duchess of Cambridge are known for their fondness for nights in with DVDs, and little brother Prince Harry has often joked that William is "middle aged".

But last night William abandoned Kate for a rare night out in Mayfair with his close friend Guy Pelly.

The Mail Online revealed that, according to sources, William looked "a little bleary eyed" and was spotted holding on to a doorframe.

The prince turns 30 on June 21, and it is believed that wife Kate will be planning the perfect party.

Sources close to the couple say that Kate is discussing ideas with some of William's closest friends in order to create an unforgettable event.

We can't wait to see what Kate will wear - but whether it's a high street classic from Reiss or some signature McQueen, there's no doubt that every single guest will be dazzled by her look.
