Halfway through her set at the 2013 CMA Music Festival in Nashville, Tennessee, Kelly Clarkson realized she was missing a very important accessory. Her engagement ring.

Ironically, earlier that day she had posed for the cover of her debut country single "Tie It Up," wearing a wedding gown and a veil and flashing her huge, yellow canary diamond engagement ring.

Clarkson repeatedly apologized to her fiancé, Brandon Blackstock, throughout her performance. The reason she gave for misplacing her $150,000 custom Johnathon Arndt ring was because she was nervous about the performance.

"This is my first official set at a country thing," Clarkson told the crowd midway through her set, according to CMT.com. "I've been nervous all day because I wanted to be good for you!"

According to USA Today, Clarkson tweeted after the show: "For all of the concerned fans I FOUND MY RINGS!!! Seriously, panicked in my head all night long .....so did Brandon haha!"

Clarkson is set to marry Blackstock this October. According to Us Weekly, Clarkson knew Blackstock, her talent manager, for years and started dating him in 2012. They got engaged in December.

"I've never been truly loved like I am right now," the singer told Cosmopolitan in January. "Brandon's totally The One. I've never been so happy."
