(NewsNation Now) — In an emotional video posted online, singer Adele announced Thursday that she will be rescheduling her upcoming Las Vegas concert residency dates because her show “just ain’t ready.”

“I’m so upset and I’m really embarrassed,” Adele said through tears. “And I’m so sorry to everyone that’s traveled again. I’m really, really sorry. I’m really sorry.”

According to adeleticketsnow.com, the Grammy Award winner’s first show at The Colosseum at Caesars Palace was scheduled to begin Friday.

“We’ve tried absolutely everything that we can to put it together in time and for it to be good enough for you,” Adele said.

The singer said delivery delays and COVID-19 “devastated” their efforts.

“I’m going to get it (the show) to where it’s supposed to be,” Adele said.

Caesars Palace, where she was set to perform, tweeted its support of the star.

“Creating a show of this magnitude is incredibly complex. We fully support Adele and are confident the show she unveils at The Colosseum at Caesars Palace will be extraordinary.”

A follow-up message promised refunds to anyone with a reservation at the hotel who wants to cancel, but said guests would need to “check with the airline” to see about reimbursements or changes for flights they booked.

Her Twitter caption said “All dates will be rescheduled … more information coming soon.”
