Sunny Sweeney will never forget her wedding anniversary. The ‘Drink Myself Single’ singer has just inked the date on her bicep. “My new “11″ tattoo,” she tweeted yesterday, showing off the still healing, shiny new ‘XI’ (the Roman numeral for 11).

“Is it because you got married on 11/11/11? Super Cute!” one fan asked. Sweeney, who married Jeff Helmer in Las Vegas on Nov. 11, confirmed that was the case. The singer says this is her eighth or ninth tattoo, including the star that’s also pictured. It’s not clear if that is part of the new ink job, but the ink doesn’t look as fresh as the ‘XI.’

Sweeney’s album ‘Concrete’ was inspired by past relationships gone wrong and is nominated for the 2011 Taste of Country Album of the Year award. Fans can vote for all 10 awards until Jan. 1 at 11:59PM ET.

The singer will return to the road in January, with dates in Paducah, Ky. and Abilene, Texas. Last summer, she was part of Brad Paisley‘s H2O II Tour.
