School victims honored at Billboard Awards; Janet, BTS shine

The show wasn't all somber though: Jackson rocked the Billboard Awards with an energetic and powerful performance of her past hits in an epic week that included her 52nd birthday and the 25th anniversary of her groundbreaking "janet." album.

In a glittery gold sweater-dress and thigh-high boots, Jackson sang "Nasty," ''If" and "Throb" as audience members such as Ciara and Tyra Banks danced along at the MGM Grand Garden Arena in Las Vegas.

Bruno Mars made a surprise appearance to introduce the singer, who earned the Icon Award.

Jackson used her speech to pay tribute to powerful women.

"Women have made it clear that we no longer will be controlled, manipulated or abused. I stand with those women and with those men equally outraged by discrimination who support us in heart and mind," she said onstage.
