Not to mention Katie Holmes and Kim Kardashian! The celebs - including Ryan Seacrest and Usher, too - are posing for the Keep a Child Alive campaign by wearing "Buy Life" t-shirts.

Co-founded by Alicia Keys and her husband Swizz Beatz, the charity provides care and support for HIV/AIDS-affected families in Africa and India. To make a $5 donation, text "WILLOW" (or the names of the other participating celebs) to 90999.

How cute are Will and Jada's kids? I have a feeling they're going to have long showbiz careers!
