ELLEN'S CAUSE

Call her DeGenerous: On July 15, ELLEN DEGENERES raised $400,000 at a Chateau Marmont poolside bash with pals including HEATH LEDGER and MICHELLE WILLIAMS. The event benefited FXB and Heifer International's 6 Villages campaign to launch self-sustaining communities in Uganda. "You give this gift to Third World countries—a cow, a sheep," said the comedian, "and they start breeding and selling them, and suddenly they have a livelihood." David Spade was at his own party, but "he said if I sang karaoke there, he'd donate." She sang and he gave $10,000.

KATE'S WORKOUT BUDDY

One secret to KATE HUDSON'S increasingly slender physique? Two-year-old RYDER. "It's just mayhem in my house now—I'm chasing after my son all the time!" Hudson told Insider at an Allure magazine dinner July 12 (she's on the August cover) at Manhattan's Gramercy Park Hotel. As for Ryder's flowing locks, "his hair is really long; he doesn't want me to cut it," says the 27-year-old actress. "I figure when he's 3, we'll give it a trim."
