I’m sure you’ve seen the Ice Bucket Challenge videos going around social media. From celebrities to your next door neighbors, it seems everyone is taking part in this charity event.

Justin Davidson, 28, got down on one knee behind his longtime girlfriend Shelby Muha, 31, as she was waiting for him to drench her in freezing water. Just as she turns around, getting ready to tell Justin to do-this-thing, she breaks into giggles– realizing that he’s proposing!

If you notice, Shelby does briefly drop the ring. Obviously she was more than shocked!

Justin’s reaction is so precious. Even from the video we can tell that he’s a shy man.

In an interview with MailOnline, Shelby said she had no clue the proposal was coming – and never would’ve expected for Justin to propose to her on camera.

‘Justin is a really quiet guy, and he’s not into big, showy things at all,’ Shelby said. ‘He’s not a limelight lover, and so even being on video freaks him out.’

Six challenges and two buckets of water later, the two are embracing as Shelby still asks, “Are you serious?” How precious!

The Ice Bucket Challenge, which has gone viral in the past few weeks, is an effort to raise money for ALS, also known as Leu Gehrig Disease. When people are given the challenge, they have 24 hours to dump freezing water over their heads – and must record it. If they do complete the mission, they give $10 to charity; if they don’t, they give $100. For more information and videos of this challenge, visit ALSA.org
