JoJo, who caused a mini-scandal in October when she was spotted at L.A.'s Hyde Lounge, says her visit to the hot spot was totally innocent.
JoJo told PEOPLE at the American Music Awards in Los Angeles:
I didn't know it was 21 and over, 
It's a freakin' restaurant and I was there with my mom and two other underage friends. I had milk and cookies! I wasn't drinking alcohol. 
JoJo, whos real name is Joanna Levesque, turns 16 on December 20.
JoJo recently landed a Top 10 hit with "Too Little Too Late," the first single off her second album, The High Road, and has been compared to Mariah Carey and Beyonce.
