Josh Groban and will.i.am joined Celine Dion onstage in Los Angeles on Saturday (12Jan08) for a low-key fan-only concert that has been filmed for a new TV special.

The concert, at the Wiltern Theater, was Dion’s first show since she wrapped her five-year A New Day residency at Caesar’s Palace in Las Vegas in December (07).

Celine Dion: That’s Just The Woman In Me will air in America on 15 February (08).
