Napster and Facebook co-founder Sean Parker turned his 30th birthday into a good cause on Saturday. The tech whiz helped raise more than $60,000 in donations for Malaria No More during a bash he co-hosted at his West Village townhouse. Also at the party were Val Kilmer, “Wall Street 2” director Oliver Stone, Sean Lennon, Lucy Liu, Gina Gershon, Josh Hartnett, Stephen Baldwin and Mark Ronson, who served as deejay.
