LuAnn De Lesseps shocked her fellow Housewives castmate Heather Thomson by telling her she's going ahead with IVF treatments, even though she was just caught possibly cheating on her much younger boyfriend, Jacques Azoulay.

Over lunch at the swanky Blue Fin restaurant, The Real Housewives of New York stars talked about LuAnn's plan to get pregnant.

"We're moving forward.  I'm going to try IVF," LuAnn says.

The decision comes on the heels of LuAnn, 47, admitting she lied to the 37-year-old Jacques about meeting up with an old friend while she was on St. Barts for the show.  Instead, she met up with a Johnny Depp look-alike and as Breaking Celebrity News exclusively reported, the handsome Frenchman now suspected she cheated on him.

The timing of her announcement about her intention to undergo In Vitro Fertilization with Jacques didn't go unnoticed by Heather.
