If there’s a sudden worldwide shortage of Swarovski crystals in the coming weeks, blame the Oscars.

Oscar producers have trucked in hundreds of thousands of Swarovski crystals to decorate the set for Idina Menzel’s performance of “Let It Go,” the best song contender from Disney’s hit toon “Frozen.”

The veteran Broadway belter performance of the uptempo tune is expected to be one of Sunday’s show-stopping moments — and with all those crystals it should be dazzling to the eye, too.

“Let It Go,” written by Kristen Anderson-Lopez and Robert Lopez, has emerged as a smash hit that has kept the “Frozen” soundtrack high on the SoundScan album chart in recent weeks.
