Voluminous in red ruffles: Queen Máxima and Real Housewife of New York's Pinot Queen, Ramona Singer.
Jumpsuit royalty: The Queen and Real Housewife of New Jersey's Teresa Giudice. (Queen Màxima is almost certainly not wearing a pantsuit, but do you want to be the person telling Teresa she's not regal-looking?)
The Queen and Real Housewife of Orange County, Vicki Gunvalson. Polka-dots!
Queen Máxima and, drumroll please, from the Real Housewives of Atlanta, Queen NeNe Leakes. (She will be the only Real Housewife, other than Ramona above, who warrants a monarchic title.)
The Queen and Real Housewife of Orange County Gretchen Rossi, in the show's opening credits no less.
The Queen and former Real Housewife of New York, Bethenny Frankel. Everyone loves a flouncy fascinator, though obviously Màxima is too classy for a (likely Skinnygirl-branded) lollipop.
Queenly greens: Máxima and Real Housewife of Atlanta's Lisa Wu Hartwell.
The Queen and Bethenny Frankel in hair curlers, because why not?
Queen Máxima and Vicki Gunvalson take #2. With Vicki's European-sounding last name, they could be like, distant relatives or something. (Or not.)
Queen Máxima and Real Housewife of Atlanta Cynthia Bailey.
The Queen and Teresa Giudice, sisters in gaudy fur.
