Bette Midler, above, and Cher, below, coming to Vegas in 2008.

All the pieces of the post-Celine Dion era at Caesars Palace are falling into place: Cher's deal is done, and Bette is set.

Cher will move into the 4,000-seat Colosseum in the spring of 2008, and Bette Midler will follow in the fall, I hear.

Dion ends her 41/2-year run, an unequaled local success, in December 2007. Depending on which reports you believe, she either plans to launch a two-year world tour or will try to have a second child through in vitro fertilization.

It was announced Wednesday that she has canceled her next five performances of "A New Day" and an appearance as a presenter Monday at the Billboard Music Awards at the MGM Grand.

She is being treated for mycoplasma bronchitis, a contagious respiratory bacterial infection.

She returns Dec. 28, after a holiday break.
