Ranky old "Focker" Barbra Streisand had her eyeglasses clutched in one hand as she awaited her cue to walk onstage and present the Best Picture Oscar - but hyper-drived into meltdown mode when Academy-authorized photogs suddenly blazed away with their cameras! "STOP TAKING MY PICTURE!" freaked the aging diva. Retorted an exasperated photog, "We are not taking your picture - we're shooting Jamie Foxx!" Jamie was just walking backstage in a blizzard of flashbulbs after his Oscar win, and all the pandemonium got senior Streisand so rattled she set her glasses on a table, then walked onstage without them . . . which is why the world watched her confess to Dustin Hoffman that she couldn't read the Best Picture winner!
