Jersey Shore Engagement: Deena Cortese Is A Bride-To Be

See the MTV alum's brand-new bling!

Save the date for an upcoming Jersey Shore wedding: Deena Cortese is engaged! And now Team Meatball is off the market, for good.

The humorous MTV alum and beau Christopher Buckner -- who made his debut on the GTL-filled hit series and subsequently appeared with his ladylove on VH1's Couples Therapy in 2014 -- are en route to the wedding altar, the bride-to-be happily divulged on Instagram post-proposal.

"I always knew I would spend the rest of my life with Christopher .. But last night while we were walking on the Beach in Mexico he made it official!! We're engaged!!!!!" Deena captioned the heartwarming collage-style image with her fiancé. Bachelorette bash at Karma, with a bit of dancing in the streets to cap off the festivities?

Be sure to offer your congrats to Deena and Chris in the comments -- and to celebrate the happy couple, enjoy the old-school clip from Jersey Shore featuring the soon-to-be Mr. and Mrs.!
