Remember how Heidi Klum owns Halloween? The supermodel takes the whole costume celebration to another level. And instead of appearing as a sexy whatever, she showed up at her 14th annual Halloween party dressed up as a very realistic elderly woman.

How did she do it? With some heavy duty makeup and prosthetics of course. She tweeted the transformation. Check it out below:
