Changes: Mariah Carey, Meghan Trainor

When you are a diva, you get to do things your way. Mariah Carey is making changes to her “Mariah #1 To Infinity” shows at Las Vegas’ The Colosseum At Caesars Palace.

The “#1 To Infinity shows” were originally supposed to end with a run from April 26 to May 13, but now those gigs have shifted to July 8-18. The artist has been returning to the Colosseum residency since May of 2015, sometimes spending months at the venue before moving to tour other regions.

Tickets to the shows are available now. Ticket holders to the April and May dates can get their ticket exchanged or claim a refund at the original point of purchase. Those that bought tickets with credit cards will be automatically refunded in two weeks if they don’t exchange their tickets for new ones.

Mariah will be performing some of her Christmas music Dec. 10-17 at the Beacon Theatre in New York. The Colosseum said in a press release it plans to book Mariah for her 2017 Christmas shows.

Sorry, Meghan Trainor fans, the pop star won’t play any more shows this year.

The singer let her people know via Instagram and Facebook.

“I posted last week that I wasn’t feeling great, but was powering through the best that I could. Unfortunately, I am not feeling any better and after leaving the doctor today, I have been put on strict vocal rest for the next two weeks. This absolutely kills me because I was so excited to see all of you on the road,” she wrote.

The next performance was supposed to be at  tonight’s Z100 Jingle Ball event at Madison Square Garden Arena in New York. She also had Jingle Ball appearances booked at Verizon Center in Washington, D.C. and BB&T Center in Sunrise, Fla.  and Phillips Arena in Atlanta.

This is definitely an anti-climactic December for Trainor, who otherwise has had a banner year in 2016. She has been touring since April and the year also saw the release of the album Thank You.
