Blond beauty Carrie Underwood performed the title track to her chart-topping new album, Blown Away, live at last night's Billboard Music Awards.

Showing off her unmistakably powerful pipes (and other attributes), Carrie commanded the stage with what she calls one of the darkest songs she's ever written.

Britney Spears joined Rihanna at the 2011 Billboard Music Awards for some "S&M" last night. Their sexy duet ended in a kiss ... which ABC moronically cut off.

It didn't last as long as Britney's tonguing of Madonna at the 2003 VMAs, but the kiss was still captured by some astute (and possibly excited) photographers!
