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?
