After a year of separation, Johnny Knoxville filed for divorce July 3 from his wife Melanie. Only a few days later he was seen in Beverly Hills letting it all hang out - smooching his new girlfriend. And she's skinny. (Remember Johnny once said the difference between a wife and a girlfriend was "about 45 pounds.") We don't know if this is the former Mercer Hotel waitress he was supposedly living with, but she might be.
