Wailing Britney Gives $25k to Idol Cause, Promotes Huge Batch of Clients

Britney Spears was so moved by Idol Gives Back last night that the grounded star called "all on her own" to give $25,000. That's almost 17 weeks worth of allowance! "She watched the show and cried for like two hours over the children in Africa with malaria," a source tells Life & Style. "She didn't know much about the disease, so she Googled it. She was horrified to realize kids were dying from mosquito bites. So she went online and donated after getting her dad Jamie's permission. She used her Amex." Who is the marketing genius behind this one? Google? Amex? Ashton?
