I don't believe Marsden was ever on "The Nanny." CORRECTION: You're right, he was on a couple episodes as one of Maggie's first boyfriends. Very nice!
If you're thinking of Maggie's boyfriend/fiancee/husband, he was played by Andrew Levitas (even hotter than Marsden, IMO). :biggrin1:
Don't know of any naked pics of either. Though Levitas did flash his buns in Hellbent.
