Congratulations are in order for a very special MTV couple!
The proposal captured by Jenna's brother Tom Compono occurred Saturday night at the Rockefeller Center Christmas tree in New York City.
"We went on one of our first dates there. Jenna actually showed up four hours late and the second she showed up and went to take a photo, the lights went out," Zach shared with E! News. "So our picture was next to an unlit tree. We've gone to the tree every year since but we've gotten there much earlier since the first year!"
"I was so surprised!" Jenna told E! News after the proposal. "We went to see the tree every year since we met and a lot of memories have happened in New York City. I was so surprised and it was so sincere and sweet. I couldn't be happier."
Before the proposal, Zach bought a special engagement ring from a family friend who owns Cooper & Binkley Jewelers, a jewelry store in his hometown of Brighton, Michigan.
"They really personalized the process from picking out the diamond to designing the band," he shared with us. "The jewelers and I sat down with their designer Simon G. Jewelry and designed every part of the ring. This is the only jewelry store I have ever spent money at and there is nobody else I'd trust more."
Fans first met Zach and Jenna back in 2014 on Battle of the Exes II. They had an instant connection that grew into a special romance. Despite a brief split during The Challenge Rivals III, they mended fences during Invasion of the Champions.
"I always kinda knew she was the one. I just knew I wasn't mature enough when we first met," Zach shared with E! News. "[I admire] her ability to put everyone else's needs above her own. She's patient with me too, very patient. And keeps my life in order."
