Sia, backed by Norwegian production team Stargate (thus explaining her presence at such a regionally specific awards night that no one's ever heard of before), dropped by the little known Norwegian-American Achievement Awards in New York City last night to perform the hit Rihanna single she co-penned with US producer Benny Blanco.

This is great for two reasons 1) she's vocally superior to the singer she gave the song to 2) she's definitely not singing about Chris Brown.

Suddenly we don't feel so icky about singing along to this.
