it was given in the intouch article that they were really busy and couldnt even plan their wedding!! their friends did that for them as she was busy shooting oth and recording her album and michael was busy recording his album with enation!! soo i kinda think it was a quick affair... that prolly is the reason nobody came!! plus it took place near washington , soo im guessing the busy schedule didnt allow the other cast members to come to the wedding!! its kinda hard to believe that she wouldnt invite anyone from oth!!
