*Willow Smith is off to a great start in her new found fame. She and her brother Jaden have joined the “Keep a Child Alive” campaign with Alicia Keys.

The siblings will join Keys and her hubby Swizz Beatz to raise money to support families affected by HIV/AIDS in Africa and India.

As well, celebrities like Serena Williams, Kim Kardashian and several others are supporting the cause.

Also going on in Willow World, the young lady is on her promotion grind. She used uStream to endorse her new website (www.willowsmith.com) and was recently seen on stage with Justin Bieber at the Staples Center in LA getting her Dougie on (see below). She also announced that she’ll be on the “Ellen” show Nov. 2.
