The the annual iHeartRadio Music Festival kicked off last night! This 2 night festival is a star studded event. Night one was a hit! Britney Spears, No Doubt, Miley Cyrus and Usher were just some of the stars that hit the red carpet that night. No Doubt kicked off the night and even performed "I'm just a girl" with PINK! Amazing! What an amazing night for music! 

What do you think of the stars outfits?
