It’s Sunny Sweeney’s Tattoo!
Sunny Sweeney got this tattoo to commemorate an important date in her life. That's a Roman numeral 11, as Sweeney married Jeff Hllmer on Nov. 11, 2011 in Las Vegas. She has seven or eight additional tattoos in addition to the two pictured. During live shows it's not unusual to see those on both arms.
The wedding was the second for both Sweeney and Hellmer. The singer told Taste of Country it was a private affair that they had been planning for awhile, and she opted for a blue dress instead of white, as she looks better in blue. Laughing, she said, "I wore white in my first wedding, but that didn’t work out for me."
