You never know what will happen at CMA Fest — something two Luke Bryan fans experienced first-hand when they visited a Chevy-sponsored tent during the festival in early June.

The ladies were singing along to Bryan’s song “Country Girl (Shake It For Me)” in the driver and passenger side of a vehicle on display, having no idea that one of their favorite artists was soon to pop up in the seat behind them.

Bryan sneaked in as the girls were jamming out, but it only took a split second for them to realize who’d jumped into the back seat. They were unable to contain their squeals at the sight of him, but kept singing along to the best of their ability as Bryan joined in.

After the singalong, the fans hugged Bryan, still excited from the whole experience.

“This is the best moment of my life!” one of the women exclaimed. Check out their overjoyed reaction in the video above.

Bryan performed at the CMT Awards as well as CMA Fest June 12, at which he took the time to hold a moment of silence for the victims and families of the Orlando massacre that took place early that morning.

“Something has been real heavy on my heart tonight,” Bryan said to the crowd of 55,000 at Nissan Stadium. “I want us to take a brief moment of silence and think about all those families that have been affected in Orlando, Florida, in what happened in our great nation last night. Let’s take a moment of silence and pray for all the families and everybody affected.”

Bryan is on the extended 2016 leg of his Kill the Lights Tour with Little Big Town and Dustin Lynch, which wraps in early October.
