Adele's Las Vegas residency has been postponed due to COVID-19.

Just a day before she was set to take the stage, the "Easy on Me" singer took to Instagram with a tearful post to let her fans know that her show isn't ready.

"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. "But we've been absolutely destroyed by delivery delays and COVID. Half my crew, half my team are down with COVID. They still are and it's been impossible to finish the show."

"I'm gutted," she added through tears. "I'm sorry it's so last minute. We've been awake for over 30 hours now trying to figure out and we've run out of time, and I'm so upset and I'm really embarrassed and I'm so sorry to everyone that traveled in."

The Grammy Award-winning singer was supposed to take the stage at Caesars Palace on Jan. 21 for a four-month-long residency titled "Weekends With Adele."

Adele previously told Rolling Stone that she didn't want to do a regular tour due to uncertainties around COVID-19, so a Vegas residency seemed more doable. As a Los Angeles resident, she said that she would be able to fly easily to and from Las Vegas and wouldn't have to leave her son, Angelo, for long periods of time.

Now, the dates of her Vegas shows will be rescheduled. Adele told her fans she will continue preparing until everything is ready.

"I'm really sorry," she said. "I'm going to finish my show and I'm going to get it to where it's supposed to be… It's been impossible."
