JoJo Is All Grown Up and Looking Hot

JoJo heated up Hollywood last night, attending back-to-back parties and turning heads at both. The 20-year-old singer was looking grown and sexy in a black skirt and sheer top while baring her toned legs at the IZOD party to celebrate the 100th Anniversary Indianapolis 500.

She then changed into a form-fitting white number and raced over to the launch of former “Hills” star Audrina’s new VH1 reality show at The Redbury Hotel, partying with Christina Milian and Rob Kardashian.

JoJo’s first album for Interscope Records is done and awaiting a release date. A video for the lead single will be shot soon.
