SPOTTED: American pop duo Karmin consisting of engaged couple Amy Heidemann and Nick Noonan performing at an outdoor concert at The Grove in Los Angeles, August 1, 2012. The event was part of the outdoor mall’s Summer Concert Series, sponsored by Citibank.

Karmin is currently named as one of two finalists in Rolling Stone’s Women Who Rock contest. Next stop for Amy Heridemann is an onstage showdown against the other finalist, Rita Ora at the Rolling Stone Rock Room during Lollapalooza . The winner gets her very own Rolling Stone cover!

“We pretty much freaked out,” Heidemann told RS about learning she’s made the finals of Rolling Stone’s Women Who Rock contest. “This is a huge deal.” Fiance and band member Noonan added. “I had resorted to physically accosting people in public to get them to vote for us.”
