Listen to Megan and Liz on iHeartRadio

Megan and Liz are not just your normal teenage girls who love to sing in front of the mirror with hair brush in hand -- they're the winners of the Macy's iHeartRadio Rising Star competition!

With big smiles, they took the massive iHeart Radio Music Festival 2012 stage and performed two songs, "Bad For Me" and "Are you Happy Now."

"This song is very special to us and is about bullying," Liz said, and the Nashville girls dedicated their special peformance to anyone who has been put down.

Megan showed her iHeartRadio spirit by being dolled up in a black dress with red lips and a chunky silver necklace.
