Adele has said she is “embarrassed” over not being able to make her marriage work.
The superstar singer has opened up to chat show host Oprah Winfrey about her divorce, her son, and her weightloss.
It was all during a two-hour special on CBS to launch her new album, titled 30, which aired in the US overnight.
It is the first time she has discussed the breakdown of her marriage with ex-husband Simon Konecki publicly and said she was “disappointed” for herself and her son, Angelo.
“I’ve been obsessed with a nuclear family my whole life because I never came from one,” Adele told Oprah.
“From a very young age I promised myself that when I had kids we’d stay together and we would be that united family and I tried for a really really long time.
“I was just so disappointed for my son, I was disappointed for myself.”
Adele, 33, said she had revealed to her friends that she was unhappy in her marriage but that it had helped her make the decision to separate from Konecki.
“I do remember with my friends … we were answering these questions in this very bougie magazine,” she said.
“It was something like ‘what’s something about you no-one would ever know?’ and I just said it.
“I was like ‘I’m really not happy, I’m not living, I’m just plodding along.’
“But it was when I admitted to my own friends who thought I was really happy … it was from there that it was like ‘well what am I doing it for?’
“I’m just embarrassed I didn’t make my marriage work.”
Despite the split she and Konecki remain on good terms, living across the street from each other in Los Angeles.
But they do not talk about her highly anticipated new album.
Adele, who is reportedly in a relationship with American sports agent Rich Paul, also admitted to feeling “very uncomfortable” that she chose to dismantle her son’s life with her divorce but could not ignore her own happiness.
“I was ignoring my own happiness … and I knew that, as an adult, Angelo would be livid with me for doing that,” she said.
“When he became an adult he’d be furious with me, and I didn’t want that either.”
She continued: “The whole album is not about him, it’s about me and I just wanted him to hear me talking madly deeply about who I am and how I feel.
“I don’t know if I’ll ever be able to have that conversation with him in real life so he can go and listen to it.”
The Someone Like You hitmaker was also asked about her dramatic weightloss, to which she said she was “not shocked or fazed” by the reaction.
Adele said she had not set out to drop almost 100lbs (45kg) and that she had always been body-positive.
“But it’s not my job to validate how people feel about their bodies,” she added.
“I feel bad if anyone feels horrible about themselves but that’s not my job. I’m trying to sort my own life out.
“I can’t have another worry.”
The primetime special also featured a pre-recorded live performance from Adele featuring never before heard tracks from 30 from the Griffith Observatory in Los Angeles.
