Want to Want MeHow could I not, this was too much fun. Jason Derulo, you're a sanging fool. Oh yeahh http://bit.ly/Sing-With-LukeBryan

As one of the most successful stars in country music, it's not a secret that Luke Bryan has vocal talent. But this duet with R&B star Jason Derulo shows a completely new area of the "Kick the Dust Up" hitmaker's range. ... And wow!

Bryan is never one to turn down a party, even an online karaoke party. The new Sing! Karaoke by Smule is a "global karaoke party," and big name artists are getting in on the fun to help launch the experience. Bryan shared this fun video with his Facebook fans on Monday morning (Aug. 10).

"How could I not, this was too much fun," Bryan writes on Facebook before calling Derulo a "singing fool."

The karaoke song of choice is Derulo's hit "Want to Want Me." The video is a split screen of the two singers, each wearing headphones. Derulo begins the song before Bryan kicks in to tell viewers (or maybe Derulo) to "go on, baby." The country singer wiggling around in his screen, moving his shoulders and acting like an all-around adorable goofball.

Even the biggest Luke Bryan fans will find it surprising how high the star can sing in an attempt to match Derulo's high octave. He gets there, though — all the while displaying a huge smile. The best part, though, is when the two sing the chorus together. It'll blow your mind.
