LANCE BASS - CELINE OPENS SEASON WITH STARS

MUHAMMED ALI, STEVIE WONDER, JANE SEYMOUR, 'N SYNC's LANCE BASS, and KNIGHT RIDER star DAVID HASSELHOFF were among the stars watching Canadian singer CELINE DION begin her 600-date stint in Las Vegas.

Celine's spectacular was also filmed for a CBS TV show called CELINE IN LAS VEGAS, hosted by JUSTIN TIMBERLAKE and the launch of her new album ONE HEART.

Celine admitted to being nervous just before the concert, telling Timberlake, "I'm scared but this is it. I've been looking for this for so long... I just hope that people will like it. That's all that matters."

She shouldn't have worried, as the audience gave her a series of standing ovations.
