A Green Day fan in Los Angeles decided that the best time and place to pop the question to his girlfriend was in front of the band, when they were appearing at a branch of Hot Topic for an in-store signing/meet & greet last week.
The trio - who have just released their new album 'Revolution Radio' - shared the video on Facebook, which shows them looking shocked (but not as shocked as the girlfriend) as her pop-punk-loving beau got down on one knee.
Thankfully, she said yes, so he won't be walking down the Boulevard of Broken Dreams alone. Let's hope her future husband doesn't turn out to be a Basket Case. (Sorry).
