Fallen popstar Britney Spears has a guest starring role on tonight’s episode of How I Met Your Mother. And despite evidence that would predict otherwise, reviews suggest she pulls off the role fairly well.

After the show, she’ll be pulling off her clothes …

For charity, that is. Her wardrobe from the appearance — including a navy print Juicy Couture dress, a yellow Nannette Lepore dress, and a cream Nannette Lepore cardigan with blue flower details — will be put on the auction block once the show airs with proceeds benefitting the Natural Resources Defense Council.

To which I say, really, Brit-Brit? The NRDC? Do they need funds more than, say, a small nonprofit producing hard-hitting but hilarious website content every day? Hit us, baby! One more time?
