Have a lucky number?  Jason Mraz does and it's the number 23.  That number plays a huge role in his life. 

Jason recently got engaged to Tristan Prettyman and says the number 23 has been significant in just about every part of their relationship.  His birthday is June 23rd.  Tristan's is May 23rd.  They met on September 23rd at a mutual friend's party.  They both have a "23" tatoo.  Jason bought the engagement ring on November 23rd and proprosed to Tristan right before the 23rd hour on December 23, 2010.  The ring is 2.3 carats and he designed the ring to hold 46 stones.  23 for her and 23 for him.   Jason says he'd like to get married within the next 2.3 years.
