Sean Penn is clearly enjoying life as a single man because he his ex wife of 20 years, Robin Wright Penn, is nothing but a ghost to him.

Robin is trying to put the past behind her and move on with her life and Sean has no problem with that because, "She is a ghost to me now," Sean said according to People magazine.

Sean Penn Pleads No Contest to Kicking Ass

"We spent all those years together … Now she's just gone," Sean told Vanity Fair in the July issue of the magazine.

Nowadays these two only reunite for the sake of their kids. Their son Hopper was recently hospitalized with a life-threatening head injury in a skateboarding accident and they both went to the hospital to be by his side.

It's sad that after 20 years of marriage, they really don't want much to do with each other. But than again Robin probably wasn't thrilled about Sean running around town with women half her age.
