Willow Smith is putting her new-found success to good use. The nine-year-old joined her brother Jaden for a 'Keep a Child Alive' campaign where the siblings don 'Buy Life' t-shirts to promote the cause. The 'Keep a Child Alive' charity was co-founded by Alicia Keys and Swizz Beatz in an effort to raise money and support families affected by HIV/AIDS in Africa and India.

The 'Keep a Child Alive' campaign has garnered support from several celebrities including Usher, Serena Williams, Kim Kardashian and British singer-songwriter Jay Sean. Fans can support their favorite celeb's charity efforts by texting the name of the participating stars to 90999 to make a $5 donation. You can also purchase a t-shirt at buylife.org.



In other Willow news, the starlet took to uStream, along with a Willowette/friend, to promote her web site and talk about her recent appearance on stage with Justin Bieber at the Staples Center. She also announced that she'll be performing on 'Ellen' on November 2.

Check out the 'Whip My Hair' video after the jump.
