Justin Timberlake Rocks the Las Vegas Strip

Only Justin Timberlake could bring the biggest names in music together for one night -- and "Extra" was there!

"I brought 'em out tonight," the 28-year-old superstar told the crowd at the Mandalay Bay Events Center in Las Vegas. The Justin Timberlake and Friends concert featured Alicia Keys, Taylor Swift, Timbaland, TLC, Snoop Dogg, Ciara and Jay Sean and benefited Shriners Hospitals for Children.

Timberlake wore his signature hat, blazer and button-down flannel and opened the show with a funky blues rendition of "FutureSex/LoveSounds." He played emcee for the night and shared the mic with Ciara and later Snoop Dogg. The pop crooner also rocked out with Timbaland for his entire set. The two performed a new track that could be on Timbaland's upcoming album "Shock Value 2."

Justin wrapped the three-hour show with a memorable set of his own. The Grammy winner mashed-up Kings of Leon's "Use Somebody" with his 2002 hit "Cry Me a River." Earlier this summer, Timberlake was spotted at the Kings of Leon concert in L.A. and recently told "Extra" he can't stop listening on his iPod to his fellow Tennessee-natives. Justin will also appear on the upcoming Kings of Leon remix album that also features interpretations from Linkin Park and Pharrell Williams.

The sexy singer was ready to call it a night after he tickled the ivories for "What Goes Around.../...Comes Around" but he played one more song and surprised the audience with a freestyle version of "Until the End of Time" for the couples in the crowd. "There are a lot of haters, but are there any lovers out there?" Justin asked.
