Kelly Clarkson, 'American Idol' winner and America's best girlfriend, picked a maid of honor for her upcoming wedding to Brandon Blackstock -- and we're kinda mad that it wasn't any of us, honestly.

Clarkson, remaining down to Earth as ever, chose her childhood best friend, Ashley Donovan, as her top bridesmaid.

The 'People Like Us' singer introduced Donovan on Twitter as her "official maid of honor," complete with the adorable photo you see above.

Clarkson and Donovan grew up together in Burleson, Texas, where they worked together as ticket-takers in a local movie theater.

After Clarkson won the 'Idol' title in 2002, the pair moved out to Los Angeles together, where they continued their low-key lifestyle of just hanging out and doing girl stuff, like watching 'Dr. Quinn, Medicine Woman' reruns -- at Clarkson's insistence!

Clarkson, 31, and Blackstock, 35, are set to tie the knot on Oct. 20 in Nashville, Tenn., and if her engagement photos are any indication, it's going to be a truly stunning ceremony.

And an undoubtedly entertaining one -- Blake Shelton is officiating!
