It isn't as if we didn't know that Rihanna's hair was a wig, but now there's proof! The international star gave a new meaning to "let your hair down" at the BRIT awards after her performance onstage.

In quintessential RiRi style, she tweeted out a photo of her onstage outfit hanging on a mirror, hair included.

If there is one thing that we all can love RiRi for, it is her dedication to keeping her fans updated via Twitter. Then again, what 24-year-old (happy belated, RiRi!) isn't addicted to the social media site?

I'm just waiting on her to discover Instagram and start making these photos look KILLER. Of course, her being in there kind of does that already. But, J.Cole uses it, and they were in a music video together, and a fake sex scandal to boot, so I mean, share the knowledge people! This photo is great and all, but I'd love to see it in Toaster mode, wouldn't you?
