Christina Aguilera is proving to her fans that her split with soon-to-be ex hubby Jordan Bratman will not have an impact on her famous pipes. XTina wowed the Las Vegas crowd who packed the Planet Hollywood Theater for the Justin Timberlake and Friends Concert for Shriners Hospitals for Children.

Before Ms. Aguilera, 29, hit the stage, Justin Timberlake gave his longtime friend the following introduction:

    "This next act is very dear to me. I've known this woman, this lady, since I was 10 years old. Multi-platinum, five-time Grammy award-winning, over 46 million albums worldwide and no contest ... the greatest voice of my generation."


Loves it! Although Christina stole the show, other performers included Elton John, Lady Antebellum, Selena Gomez, Salt-N-Pepa and Diddy.
