I believe it's in the contract for participants Bravo reality shows like Real Housewives, Top Chef, etc. to appear on Andy Cohen's show when asked. So they may not be getting paid extra for appearing on Watch What Happens, but if they don't do it they won't get their payment for appearing on the show.
But also what a pair of liars and idiots. They are getting exactly what they deserve.
So Joe claims that "people" just gave him the false W2 forms etc so he could qualify for a mortgage and he signed them without knowing they were wrong. So how does that work? Who's Photoshopping in extra digits on the W2 forms and bank statements?
