Did Melissa Gorga eat too many of Kathy Wakile's sweet treats?

The Real Housewives of New Jersey star stunned onlookers in New York City's Times Square when she filmed a segment for Entertainment Tonight Monday. Wearing a fat suit, the usually svelte "On Display" singer, 32, went incognito to see if people would treat her differently as a plus-size woman.

The Bravo celeb was joined Jersey Shore's Nicole "Snooki" Polizzi, 23, who said the Real Housewives star looked "sexy" in her fat suit; the segment will air Thursday.

Gorga isn't the first star to don a fat suit for Entertainment Tonight: Vanessa Minnillo, 30, pretended to pack on the pounds for a November 2006 special report.
