'Real Housewife of Miami' star Joanna Krupa and her fiance Romain Zago seen hitting Miami beach this afternoon for a work out and some lessons in self defense. Romain, a brown belt in Jiu-Jitsu, was seen instructing skimpily dressed Joanna in some self defense moves. They were spotted practicing some boxing, squats and push ups. On this week's Real Housewives of Miami, Joanna was punched by cast mate Adriana De Moura over a clash with Joe Francis. Joanna has made no secret of the fact that next time someone tries to attack her, she would like to be prepared.
