How cool is this! Here's how it went down. Back in the Summer, Branka Delic (from Australia), started an online petition to get Jon to walk her down the aisle since he was going to be in Vegas the same weekend for his tour. So she tweeted and Facebooked and pleaded and well, it WORKED! He actually SHOWED UP and walked her down the aisle!!!
I kind of have an idea of WHY he did it. Get this cool tidbit, the wedding was the the Graceland Wedding Chapel in Las Vegas, where 24 years ago Jon married wife Dorothea at the exact same venue!
Check out the pic and Jon's tweet:
