American Idol's Top 9 contestants sung their hearts out during last night's Rock and Roll Hall of Fame songs episode! And while only three ladies remain (let's go, girls!), they scored an awesome treat for the show—getting styled by Gwen Stefani! The No Doubt singer dressed the women in clothes from her L.A.M.B. collection, the show's costume designer Soyon An said, while all the jewelry was by Noir. "The girls were very excited to meet Gwen," An told InStyle. "They loved her and thought she was the sweetest." Pia Toscano wore a printed jumpsuit, Haley Reinhart tried a gray plaid tunic over leather pants, and Lauren Alaina performed in a checked romper and tuxedo-style jacket.
