Brit Brit: The Cure for Global Warming?

Instead of putting Britney's wardrobe from "How I Met Your Mother" in a HAZMAT bag and burying it in the desert -- her rags are being auctioned off for an organization that's all about the environment.

The half-dozen items worn by the popwreck-in-repair are part of an online auction that will benefit the Natural Resources Defense Council. The auction begins Monday night -- right after the Spears episode hits the airwaves.

No word on if panties are included, but given Brit's fashion history -- we're guessing there aren't any to give away.
