Cher's residency at Caesars Palace will be coming to an end in February 2011. She will be performing at the Colosseum from now through October, then taking a two month break and returning in January up until her final show on February 5th.
The timing coincides with Celine Dion's return to the Colosseum at Caesars March 15, 2011. Dion will perform about 70 dates a year, and already has 50 dates booked through August.
With Cher leaving and Celine only doing a limited schedule there have been rumors of possible headliners that will join the Caesars lineup for 2011. Neil Diamond and Madonna have been mentioned, but they both seem highly speculative at this point. Rod Stewart is also playing some shows at the Colosseum in November, so he might be a candidate for a permanent residency.
