It's a pretty hot time in Las Vegas for music residencies.
Reba and Brooks & Dunn have recently begun their show at The Colosseum at Caesars Palace. They talked about their residency in a CMT interview.
Pitbull will be doing a mini run from September 23 to October 7 at the AXIS Theater at Planet Hollywood.
Speaking of Planet Hollywood, Jennifer Lopez will be doing some shows at the AXIS Theater starting in January 2016. It looks like a fairly limited run though, with only a handful of dates each month in January, February, May, and June. I suppose more dates could be added later.
Britney Spears also seems to be going strong at PH, with frequent show dates scheduled from now until December 31, 2015.
