The L.A. Gay & Lesbian Center announced that rock legend Ozzy Osborne, Grammy-nominated Natasha Bedingfield and singer-songwriter Sia will perform at this year's "An Evening with Women" on May 18 at the Beverly Hilton Hotel. Two-time Emmy winner and five-time Grammy nominee Kathy Griffin will host the night's festivities. With the help of co-chairs Annie Goto, Kelly Lynch, Shannon Del and Brent Bolthouse, last year's benefit raised more than $450,000 for the Center, which provides food and shelter for homeless youth, services for seniors, legal assistance, domestic violence services, mental health services and cultural arts programs.
