What happens in Vegas, sometimes ends up on Instagram.

Carrie Underwood revealed her mom asked to get matching tattoos while on a family trip to Las Vegas with Carrie and her sisters. 

"When your 74-year-old mother asks you and your sisters to get matching tattoos with her in Vegas, the only questions are, ‘what?’ and ‘where?’" Carrie wrote on social media. "I never would’ve thought I’d see the day that Mama Carole would be gettin’ some ink!" 

Underwood recently wrapped the first few dates of her "Reflection: The Las Vegas Residency" at Resorts World Theatre.
