Julianne Hough has seen lots of great moments in her 24 years, as she's done some major film work, won 'Dancing With the Stars' and had hits on the country music charts. Yet, one of her greatest moments involves country star Blake Shelton, and it doesn't have to do with dancing or singing -- but it does involve tequila.

The blonde songstress became pals with the 'Boys 'Round Here' hitmaker a couple years ago, while they were both on tour with icon George Strait. And, while on the road together, Hough recalls something that will stand out in her mind forever. “We both opened up for George a couple of years ago,” she tells Access Hollywood Live. "We may or may not have done tequila shots on George Strait’s bus at one point. [That was] the greatest moment of my life possibly!"

Certainly, even the biggest country stars can't all say that, and it's probably a memory the 'That Song in My Head' singer will tell her kids and grandkids (once they're old enough). Ever since the tour, she's stayed friends with Shelton, and a friendship like that has its perks -- especially for 'The Voice' finale. Hough's nieces were in town for the event, and she reveals, "I'm friends with Blake, so he got us tickets."

She was probably very excited to see that the crowned champion that evening was a fellow country singer that her pal Shelton coached throughout the season. In fact, it most likely felt a little nostalgic, as Hough, a two-time 'DWTS' winner, isn't a stranger to helping promising individuals end up on top.

But according to her, nothing beats tequila shots on a legend's bus.
