Mark Wahlberg stopped by The Late Show with David Letterman last night and guess what- at age 37 he's still wicked hot.  Mark was there to promote his new movie, the latest M. Night Shyamalan project, The Happening.  It's labeled as a thriller but even Mark has said it's one of the scariest movies he's ever seen (therefore I will not be seeing it, feel free to spoil it for me)! The Happening opens this Friday.
