Buddies Luke Bryan and Blake Shelton had a little fun ribbing each other on social media yesterday. It all started when Blake shared a fake story about drivers falling asleep to Luke’s music.

“Wow! Just catching up on the news…” Blake tweeted. “Shocking! I have noticed some fatigue when @lukebryanonline comes on..”

Well, Luke wasn’t about to let it end there. Referring to Blake’s two duets, “Happy Together” and “Nobody But You,” with girlfriend Gwen Stefani, Luke cracked, “Your girlfriend is the only reason people are listening to your last two singles.”

To that Blake replied, “Hey, don’t hate just cause I know how to work the system!!!”
