Even Heidi Klum isn't always glamorous.

The "Project Runway" host posted two Instagrams that show how she goes from her natural self to the supermodel that graces all those magazine covers.

In one picture, Klum is makeup-free and has slicked back wet hair, a look that we don't typically see from her.

In the after shot, she is completely made up with her flawless skin and hair teased to make her look va va voom.

Klum, 41, gives credit to her makeup artist Linda Hay and hair stylist Brent Lawler for the after look.

Another look that Klum rocked on Wednesday is one that's definitely not her own. She captioned an Instagram pic asking if fans can guess who she's shooting a new music video for, but it's none other than singer Sia's classic bob that totally gives it away!

Can you guess for who i am shooting new music video ? ��

There's only one question that remains. Will Klum dance like "SNL" alum Kristen Wiig did for Sia at the 2015 GRAMMYs performance of  "Chandelier?"
