Billy Joel has done alright for himself. Multiple car accidents and drinking problems aside, this is a well-known, acclaimed, rich singer.
One that has been married to Christie Brinkley.
Meanwhile, Joel has also fathered a young, hopeful singer: Alexa Ray Joel. There's just one problem:
Some people mix up this 20-year daughter with her 25-year old step mother. Indeed, Katie Lee Joel - host of Top Chef - tied the knot with Billy a couple years ago and won't exactly get confused with Anna Nicole Smith, either.
It would be awfully embarassing if Billy ever got his two girls mixed up. But do you know which young hottie is which?
