Former "Jersey Shore" star Angelina Pivarnick is slamming rumors that her engagement to David Kovacs was nothing more than a publicity stunt -- and she's got the new rings to prove it!

Angelina Pivanick Engagement Ring
Pivarnick, who got engaged last week on the red carpet of a New York Fashion Week show, tells TooFab "The publicity stunt thing is bulls**t. Me and my fiancé are very happy together."

Angelina also showed off the two new wedding bands David added to her engagement ring, telling us "Why would he spend the money if this was just a publicity stunt?"

We're told the two new diamond bands cost about $4K and the couple is going shopping for wedding dresses and apartments in the Upper East Side next week.

Check out the new bling and more photos of the couple's engagement in the gallery above!
