Adele said she was “embarrassed” by her divorce, in an exclusive and wide-ranging interview with Oprah Winfrey.
The star said she felt like she had “disrespected” the idea of marriage when she separated from her husband, Simon Konecki, in 2018.
She added that “terrifying anxiety attacks” after the divorce prompted her to adopt an exercise regime that led to her losing 100lb in two years.
The US prime-time special marked her first TV interview about her new album.
It also saw the star perform a selection of new songs and classic hits at the scenic Griffith Observatory in Los Angeles, in the shadow of the Hollywood sign.
Attended by stars like Lizzo, James Corden and Melissa McCarthy, the twilight concert was the first time Adele’s young son, Angelo, had seen her perform live.
“It’s the absolute honour of my life, baby, to have you here tonight,” she said.
During the show, the star even helped a local man propose to his girlfriend, Ashley – serenading the couple with Make You Feel My Love after the stunned bride-to-be said “yes” and burst into tears.
“Thank God she said yes, because I didn’t know who I was going to sing this song to next,” Adele laughed.
The music was interspersed with interview clips, recorded in the same California rose garden where Winfrey spoke to Meghan Markle and Prince Harry earlier this year.
Broadcast on CBS in the US, the two-hour special is not currently scheduled for transmission in the UK. A separate ITV programme, An Audience With Adele, hosted by Alan Carr, is due for broadcast on Sunday, 21 November.
