The Streisand Has No Faces

Barbra Streisand kept her infamous mug covered outside Madeo ... maybe she doesn't want to subject us to this again.

Also in L.A.: "Dancing" stars and hasbeens partied at One and Dolce, Kelly Slater tried to sic water-balloon tossing kids on our cameras and Hilary Duff used Villa's curtain cave while her bf hobbled out the front door on crutches.

In NY: Kristi Yamaguchi showed off her mirrorball trophy, as losers Jason Taylor and Cristian de la Fuente stood neaby, Dina and Ali Lohan pimped their show and Debbie Harry went all Rihanna and whipped out an umbrella to keep the camera away.
