TMZ: Governor Hit the Bar with the Mistress

TMZ STAFF AT TMZ

We've been on the hunt in Buenos Aires, Argentina and found the bar where Governor Mark Sanford brought his mistress -- so how do you say PDA in Spanish?

Carlos Soto, the owner of Guido's Bar, says he's seen Sanford and Maria Belen Chapur there several times over the last few months -- most recently last week.

Soto says they were "all over each other" last week in his bar, "kissing, holding hands and drinking wine."

Soto was impressed with Maria, saying she has "un cuerpazo'" -- translation: a banging body.

Soto also said Maria has green eyes and dirty blonde hair.
