Oh, so this just makes it all better, right?

A source tells People magazine that Jon Gosselin and his 23-year-old girlfriend Hailey Glassman didn't start dating until after Kate filed for divorce on June 20, and get this - the couple has been separated since last year!

Shortly after the reality TV stars ended their romance, Jon moved out of the couple's bedroom and slept elsewhere in the house, and this May, Jon was crashing at Dr. Lawrence Glassman's house in New York City. As you may already know, Dr. Glassman was Kate's plastic surgeon, and People reports that when his daughter Hailey came home in early May for Mother's Day, she was surprised to learn that Jon was staying with her parents. Sounds innocent enough, but we're sure Kate has her side of the story too, and quite frankly, we'd love to hear it!

So what about that other 23-year-old Jon was caught with last year? A source close to the father of eight tells the mag that the two were just friends, and that no affair ever took place. Uh huh!
