Celebvocate!

Cause: RAINN (Rape, Abuse & Incest National Network), which operates phone and online hotlines for victims of sexual assault.

Site: Cocktail benefit at downtown headquarters of Navigators Global, after a day of lobbying on the Hill.

What she wants: More funding for mental health and other victims' programs. "Everyone knows someone who's been affected by this issue," said Ricci, the group's national spokeswoman for three years.

How she looked: Chic and tiny (5 foot, size 0), sleeveless black dress and sky-high heels, hair pulled back.

Backup: Rep. Jane Harman, who dashed off to the Capitol for the president's speech; former WWE wrestler Mick Foley, a teddy-bearish bruiser with long brown curls and two missing front teeth.

Charity innovation: Washington's first pay-per-tweet benefit. Donors got a dozen or so live reports from blogger Ana Marie Cox. "Low Twitter volume -- but it's exclusive," she told us.
