The adorable blondes, in Hawaii filming a flick as mommy and daughter, triggered giggles when Wardrobe delivered identical vacation costumes to their dressing rooms — but stupidly switched their sizes!
“It was hysterical,” said My SpyWitness. “Amy yanked Goldie’s shorts up over her voluptuous thighs and ass — and ripped ’em wide open!
“But Goldie’s been wonderful — she rouses Amy to run with her every morning, and monitors her diet choices — but it’s still a struggle!
“In one movie stunt where both had to jump a fence, Goldie had no problem — but producers were forced to install tiny, concealed stairs as an Amy aid!
“Goldie could not stifle her giggles — but the gals still play like total pals!”
