NSYNC and Social Network star, Justin Timberlake enjoyed a rowdy “Stag Party”last weekend with his pals who decided to “moon” for the cameras. The 31 year old singer was enjoying his stag with friends in Cabo San Lucas, Mexico, when his friends decided to show off their back sides to the on looking media. Unfortunately for Timberlake fan’s, Mr sensible “Timberlake” did not get caught up in the euphoria like his friends and only decided to “half moon”

TIMERLAKE (FAR RIGHT) RELUCTANT TO MOON INCASE IT UPSETS JESSICA

Justin’s stag party comes prior to his wedding to American actress, Jessica Biel, star of the 2012 version of Total Recall. Funny enough the pair who are engaged have still yet to release a date for their wedding which they are hoping to be a private affair, out of the eyes of the media, good luck with that Justin.
