Thanks for clarifying Jess' dad's girlfriend and Luke's daughters mother...I thought they were the same actor...I was not sure at first
John Stamos was Uncle Jesse on Full House!
Recently he was on ER as a paramedic, and he has a show called "Jake in Progress"
He's hot!

I'm not sure who I'd want to guest on Gilmore Girls, but I did notice something interesting. I read that actress Sherilynn Fenn has been cast as April's mom... Luke's ex. Did you know she also played the girlfriend of Jess' dad in the "Here Comes the Son" episode?
