Christina Aguilera is getting back into the swing of things. The suddenly single singer performed at The Justin Timberlake and Friends Concert
in Las Vegas on Saturday, and RadarOnline.com has the pop star's sexy photos.
Aguilera, 29, rocked the stage with Justin Timberlake, Sir Elton John, Salt N Pepper and T-Pain at the Planet Hollywood Resort & Casinos Theatre For The Performing Arts. The concert was a benefit for Shriners Hospitals for Children.
"Christina looked amazing and totally kicked butt," a concert onlooker tells RadarOnline.com "She sang her song Fighter. She was terrific."
This is the first performance in which the singer has participated since she filed from divorce from her music producer husband Jordan Bratman.
In recent months, the singer and Bratman have had a tumultuous relationship. As RadarOnline.com exclusively reported last Thursday, Aguilera was taken by Bratman to Cedars-Sinai Medical Center emergency room on October 12, just days before they announced their shocking split.
The Beautiful singer asked for joint legal and physical custody of their two-year-old son Max and for any spousal support to be terminated.
Since her breakup, Aguliera has been leaning on close friends like Samantha Ronson for emotional support.
