McEntire busted out “It’s Now Or Never”, a popular Elvis Presley song that was adapted from “O Sole Mio”.
The two country stars decided to take a much needed breather in Rome when they came upon an alleyway restaurant.
“We were just eating and all having a good time and there was a whole table of young students from L.A. behind us,” Ronnie Dunn tells PEOPLE. “They broke out a great big bottle of grappa – it was huge! – and we were passing that around and before I know it, Reba was standing up singing.”
Dunn was hesitant to join in, especially since he didn’t know the lyrics.
“You can see from the look on my face that I’m either thinking, I can crawl under the table or I can join in here. Reba, with no inhibitions whatsoever, just stands up and started singing it and away she went. I’m thinking, ‘Oh no, we’re going to get booted out of here!'”
Dunn posted a photo to his official Facebook and let’s just say, his expression tells all.
Luckily, they didn’t get kicked out, but received a standing ovation instead. It was well-deserved, because Reba absolutely nailed her spontaneous rendition.
Check it out! Y’all won’t be sorry.
