Only in Vegas!

Johnny Depp and wife Amber Heard went country on Dec. 11 in Las Vegas, where the newlyweds were spotted in the crowd at Reba, Kix Brooks and Robbie Dunn's sold-out show at the The Colosseum at Caesars Palace.

Afterward, Johnny, 52, and Amber, 29, joined the country stars backstage where Reba, 60, and Ronnie Dunn's wife Janine fangirled a bit.

"@janinedunn and I loved getting to visit with Johnny Depp and his group last night after our show at Caesars," Reba wrote on Instagram the next day along with a photo. "What a nice man!!!!#chocolat #findingneverland."

If you're scratching your head wondering how the actor ended up hanging out with country music's elite, don't worry -- we were too.

Then Ronnie, 62, shared a photo with Johnny on his Instagram page and explained how they know each other.

"It's a small world!! Johnny Depp dropped by the dressing room last night after the Caesars show with wife Amber," Ronnie wrote. "She was in our RED DIRT ROAD video!"

So that's it! Amber was just 17 when she appeared in the 2003 Brooks & Dunn clip, which can be seen on their YouTube VEVO channel.

"Reba, Brooks & Dunn: Together in Vegas" wrapped up its current slate of residency performances one night after the Depps' visit and will return to the Vegas stage for a new set of shows in May 2016.
