AceShowbiz - Mariah Carey's Las Vegas residency came to an end, but not on a high note. The "All I Want For Christmas Is You" hitmaker concluded her "The Butterfly Returns" residency at the Colosseum at Caesars Palace in Las Vegas on Saturday, February 29 amid reports she struggled to sell its tickets.

For the final show, the 49-year-old singer rocked a plunging black leotard with a detachable black skirt. At one point, she removed the skirt to reveal a pair of nude fishnet tights and matching platform heels. She wore her long blonde locks down and showed off her beauty through glam palette of makeup. She was also seen donning a classy pink gown for the stint.

While the "Touch My Body" singer delivered stunning performance, her residency apparently didn't fare well in the ticket department. According to Radar Online, she gave free tickets to selected people in order to make sure "sold out" shows even though the highest ticket for her residency was sold for an average of $100.

"Every high roller and whale who's flying into Vegas is being given free tickets to her show," a source told the outlet. "They're being handed out at sports books, included in room service bills and slipped under doors all over the hotel. That's why she wanted a residency and not a tour - because she's not selling out like she used to."

"The Butterfly Returns" residency was a follow-up to Carey's #1 to Infinity residency which lasted from 2015 to 2017. First launched in July 2018, it got extended for additional February 2019 dates a few months later. Its latest run was for eight February 2020 dates. Radar Online claimed that ticket sales had been low since the beginning, forcing her to sell them at discount sites back in 2018.

Carey's next move will be headlining Britain's world famous Brighton Pride event. On Valentine's Day, organizers confirmed that she will perform at the LGBTQ+ event in August. Their announcement tweet read, "Excited to announce global superstar @MariahCarey, GRAMMY & GLAAD Award winner, and best-selling female artist of all time, will headline FABULOSO Pride In The Park on Saturday 1st August 2020 with a full 75 minute show!"
