Thought Harper's Bazaar's makeover of Susan Boyle was amazing?

Well, "youse" ain't seen nothing yet.

For its May issue, the fashion magazine has done the unthinkable: turned the "Jersey Shore" "Guidettes" into glam charm-school grads.

Etiquette expert Lizzie Post and socialite Tinsley Mortimer co-star with Snooki, Sammi Sweetheart and JWoww in a photo shoot that sees the rough-around-the-edges trio getting schooled on fine dining, ladylike postures and etiquette.

And while the reality starlets may not be drafting thank you notes on Smythson stationery just yet, their tutelage has paid off.

The magazine makeover culminates in classy black and white shots of three graceful young ladies, clad in tasteful gowns from Marchesa and Pamela Dennis, with nary a pouf in sight.

Which begs the question: Who are you and what have you done with our Snooki?!?

Judging by the behind-the-scenes video from the shoot, it sounds like the magazine had its work cut out for it.

"I used to take etiquette school," Snooki confides. "I know a couple things already. I just haven't been using them."

You don't say.

According to the accompanying article, Snooki also rolled up to the shoot in a trucker hat, while JWoww attacked from all fronts in "a hooded pink sweat suit, Ugg-style boots, a studded Christian Audigier bag, purple-streaked hair and a hot-pink, bedazzled French manicure."

Surprisingly, she wasn't shot on sight, and even took time to show off her diamond ring.

"It's just a commitment ring," JWoww told the magazine. "It's part of a $22,000 set my boyfriend got me for Christmas -- a ring, necklace and earrings. I got him a ring with diamonds too."

Unfortunately, it doesn't sound like the girls' lessons in refinement and toned-down makeovers will stick.

"It hurts," Snooki complained. "I'd rather just pose in clubs."
