The Victoria's Secret beauty was working in Rome, Italy when the post-tropical cyclone struck America's East Coast on 29 October (12), destroying thousands of properties and leaving millions without power.
Prinsloo's apartment in Manhattan's East Village neighbourhood was flooded, and she decided to head to Levine's L.A. home in the aftermath of the tragedy - and she's still struggling to come to terms with the level of damage.
She tells UsMagazine.com, "Half of it was, is, underwater. My street was a river. The pictures have been scary. I cried on my kitchen floor for over an hour. At least no one got hurt - my cats are safe. It was overwhelming coming into my house and the water was over my piano.
"I found that all my material things don't matter; it's all about love for my friends and family. It helped me realise that. My building (managers) has been great pumping out the water and getting my couches out."
Prinsloo also reveals bosses of the famed lingerie line have handed over cash to the clean-up effort: "Victoria's Secret has donated a bunch of money to the Red Cross, and everyone else should, too!"
