Reba McEntire has booked several weeks of concerts at the Las Vegas Hilton next summer, rather than touring the U.S. Her scheduled dates include May 3-7, June 7-18 and July 19-30, to coincide with the summer hiatus of her sitcom, Reba. The Hilton is also home to Barry Manilow's showroom, where McEntire will perform. The concert series is titled Key to the Heart, and tickets are $138-$225. McEntire released a compilation of her hits, Reba #1's, in November.
