Enough already! These two appear to be in a contest for the Biggest Fame Ho Award ... and they're tied!

Topshop heiress Chloe Green has her jewel-covered claws deep into hot convict Jeremy Meeks who hit the runway in Paris recently for Fashion Week and then went straight to vacay in Turkey to join Chloe on her dad's yacht. Ahhh, yes -- such is our society these days that a dude who gets famous for his sexy mugshot suddenly skyrockets to fame, is "discovered" by a modeling agency, is hired by the hottest labels in fashion to represent them on the catwalk and then ditches his wife and kid for a younger, less hot, but super-rich heiress to the Topshop fortune. Uh ... good for him?!

We spotted the two -- and by spotted, I mean, followed the scent they left for all the paparazzi to follow -- at LA's Grove outdoor shopping mall Friday evening, walking hand-in-hand, smiling for the cameras and making out when they were sure our lenses were in focus. Awww, so sweet!

Meeks' recently filed for divorce from his wife of eight years with whom he has one child.
