When Christina saw a video of a beautiful marriage proposal at a Taylor Swift concert, she made sure to tell her boyfriend David she would love a proposal just like that one. Well, David never forgot and planned a dream proposal at the next Jonas Brothers concert. The problem was that COVID-19 delayed those plans. It wasn't until there was finally a show at Red Rocks in Colorado that David had his chance. Not only was it the proposal of Christina's dreams, the Jonas Brothers saw it all happen and cheered on the happy couple.
