I suspect you are right, but do we know for sure? He's always canoodling with this one and that one ... the latest being Terry Hatcher and Zellweiger, but he manages to dump them in short time....also seems to be drinking a lot more these days which tells me the man has demons.
Renee and Terry and all of the beautiful models and actresses are beards. No relationship has lasted longer than a root canal.
He also made a comment the other day about playing Batman as "gay". I thought that was rather telling as well.
He's certainly put a lot more effort into being a stud than Rock Hudson ever did.
