“The engagement was definitely one for the books! His idea was so original and he left me speechless,” she previously revealed to E! News. “As I looked over his shoulder, MTV was there behind the trees and I had no idea they were going to be there. He asked me to marry him and I said yes! We were both in tears.”

The reality star added that they will either get married this summer or next summer, but now that they’re ready to move into their new home, fans are hoping it’s sooner rather than later!
