The singer-songwriter had been due to perform her Weekends with Adele show twice each weekend from 21 January until 16 April 2022 at the The Colosseum at Caesars Palace Hotel.
“I’m so sorry, but my show ain’t ready,” she told fans, confiding that she was “really embarrassed and so sorry to everyone that travelled [to the show].”
While some fans have expressed outrage at the last-minute cancellation, others expressed support for the artist – which she acknowledged this morning (22 January) on Twitter.
“I have the best fans in the world!” she wrote.
“Your graciousness and love tonight is overwhelming! Thank you.”
