Luke Bryan scared his wife while riding her bike & the video is HILARIOUS!

I honestly can't stop laughing at this video hahah. Luke Bryan posted this video last night and it's exactly what we needed to see right now! Apparently Luke Bryan has big freakin' train horn on his truck, and he used it to scare the crap out of Caroline! So much so it knocked her off her bike and it's too damn funny to watch! Talk about couples goals right here!
