Kate Middleton's Better Half Prince William Celebrates 31st Birthday (PICTURES)

Happy Birthday Prince William!

Father-to-be and future King of England Prince William turns 31 on Friday.

If you’re wondering what to buy William Arthur Philip Louis Windsor for this milestone, bear in mind he was granted his own personalised coat of arms for his 18th – so a Lynx travel set is not going to cut the mustard.
