Fred Willard might be an alleged public masturbator ... but his wife's standing by his side 100%.
Fred was out in L.A. yesterday where he was bombarded with questions about his recent lewd conduct arrest -- when cops say they found him jerking it in an adult movie theater -- but the most interesting part ... his wife Mary was present too.
We haven't really heard a peep from Fred's wife since TMZ broke the story of the actor's arrest, but the couple has clearly decided to show a united front.
As we reported, Fred will NOT be prosecuted for lewd conduct. Prosecutors have decided they'd rather send him to crime education classes instead.
