Carey, 49, is planning a Las Vegas residency titled “The Butterfly Returns” in February with eight dates listed.
But it seems the superstar singer is failing to sell out with nearly half of ticket sales still available for each show.
For the February 14 and 15 shows at Caesars Palace, which are weekends shows, over 1,200 tickets still remain.
And the weekday concerts are even worse. On Wednesday, February 19, a whopping 80 percent of tickets remain available.
