Nicole Polizzi has changed dramatically since the pouf and those wild nights at Karma -- but there is no erasing those classic memories of the "Jersey Shore" star. Case in point: The mother of two got a special mention during "The Bachelor" last night for her past behavior -- specifically, one of Ben Higgins' ladies (single mother of two Amanda Stanton) telling another controversial fellow contestant (Olivia Caridi) that she was a "hot mess" like the "Snooki & JWOWW" star. One word: WAHHHHHHHHHHHHHHH.

And, appropriately, the future "Celebrity Apprentice" cast member didn't miss a beat with her response to the shout-out.

So what spawned the comment about 1/2 of Team Meatball? Coincidentally, Olivia telling Amanda -- who is a single mother of two -- that her life reminded her of another MTV show.

"I feel like it's an episode of 'Teen Mom,' you know that show?" Olivia blurted out (as seen in the clip above from the ABC program), while interrupting Amanda as she discussed her childcare situation with some other gals. ZINGGGG.

And that's what prompted Amanda to say that Olivia reminded her of the lovable guidette and her time in Seaside Heights -- and the rest is history.

Be sure to keep watching "Teen Mom OG," every Monday at 10/9c -- and catch a sneak peek, below, of next week's episode featuring Bentley and Jayde going trick-or-treating!
