Mon dieu!

She married (and then divorced) royalty, had two kids and even ventured into pop music.

And now, Real Housewives of New York's Countess LuAnn de Lesseps is going to act -- in the semi-nude!

De Lesseps, 45, will debut her thespian skills in an episode of Law & Order: SVU, playing "an eccentric art patron who poses semi-nude for a painter," the New York Post's Page Six reports.

The divorced Bravo star is set to shoot her scenes at NYC's Chelsea Piers this week, with the episode airing on NBC Feb. 23.

Believe it or not, de Lesseps is reportedly the first NYC Housewife to land an acting gig. No word on whether de Lesseps will get to croon her dance hit "Money Can't Buy You Class" during her SVU appearance.
