He's an adulterer. She's a serial-fiancee.
Look at the number of men she's slept with in the past few years: her first husband, the waiter...then she did Marc Anthony, then Puffy or Diddy or whatever the hell his name is now, then she married that Judd fellow who was her dancer, then before she even got divorced she was doing Ben Affleck, and now she's doing Marc Anthony again....and, I might point out, he only got divorced 4 days before their wedding. So, that's 6 dudes she's fucked, and those are just the ones we know about. Can you imagine how many more there are that we don't know about?
Brad-the-blunt is right...she's a skank. I'm all for women being able to satisfy their sexual needs, but Jenny takes it too far.
