A Westchester model who donned sexy lingerie and moaned in delight for a diamond dealer’s online ad is suing because the video is more G-string than G-rated.

The unidentified beauty has slapped Szul Jewelry Inc. with a $5 million suit on grounds it conned her into appearing in the ad. Court papers say the spot is set to “bump-and-grind” music and has “a decidedly pornographic look, feel and sound.”

“This was a bait and switch,” her lawyer, Kevin Mulhearn, said of the ad, which has been viewed more 10,000 times on YouTube.

“She can live with a comedic spot that has a touch of sexiness at the end, but it’s certainly not okay for her to be in something that’s quasi-soft-core porn.”

The 35-second “Rock Her World” spot features the model rubbing her teal teddy and purring with pleasure to the hard-grinding sounds of a guitar as the slogan, “Jewelry works every time” pops up onscreen.

GIRL PLEASE! WHAT ELSE COULD YOU HAVE BEEN DOING SQUIRMING LIKE A PIECE OF SPAGHETTI!
