Get 'em while they're hot!  Last night, Mary-Kate's boyfriends of present and past were gathered together at the United Nations in New York last night.  The party was to celebrate Lapo Elkan's new anointment of UN ambassador; coincidentally Mary-Kate's ex, Stavros Niachros was also in attendance.  They have a lot in common; they're both European, they both are/were heirs and they have both had the fortunate experience to date one weird, little Monchichi!

Mary-Kate loves the scumbags bad boys.  Meet Lapo Elkan, the newest member of Mary-Kate's dude posse. We spotted the Italian transplant in NYC yesterday.  Lapo's reputation precedes him internationally; he was formally the heir to the Fiat fortune but blew it when he was found overdosed on coke and smack in a room full of tranny hookers.  Woops!  MK and Lapo were first spotted together at Paris fashion week, seen here.  (MK had on her creepster shades.)  We'll keep our eyes peeled for this hot item, although in MK's world, her boyfriends are rotated on a bi-weekly basis, so don't expect him to be in the long haul!
