The actress took to Twitter on Sunday, December 23, to upload several touching photos from the romantic proposal, including a picture of her incredible diamond engagement ring.
"I said yes!" Debby captioned the snaps. "Well technically I said 'NO WAY' twice but I meant yes."

In the images, the 25-year-old looks shocked as Josh pops the question, and then breaks down in tears after accepting his proposal.
The drummer also shared a few snaps on Instagram, and revealed he searched for a special place to pop the question.
"I found a tree house in the woods in New Zealand and proposed to my girl," the 30-year-old musician wrote. "She my dude for life (sic). I love you Debby."
The couple starting dating in 2013, but have had an on-again/off-again relationship ever since.
However, Debby confirmed in an interview with The Sydney Morning Herald in August that she and Josh were once again an item.
"I'm in love and very happy," the former "The Suite Life on Deck" star said. "We've evolved and grown so much in our careers, in the relationship, as people since we first met. It's cool and special to have that support system and we are each other's biggest fans."
