"I read somewhere, and I don't know if it's true or not, that (her son) said when he was 16, 'I want to know now why everyone loves you.'
"And it makes me so emotional. After that show, it was: 'I don't want to wait. I don't want to wait till my kid is 16, I want to show him (my son) now.' After that, I was: 'I don't care if no one wants me to make another ... record. I'm making one for myself."
Adele scored a huge hit with her comeback album 25, which broke a number of records following its release last month, and the singer recently announced plans for her first major tour in 2016.
She previously insisted she was reluctant to tour because of the "lonely" lifestyle.
But Adele has now revealed she is planning to take her partner Simon Konecki and their son on the road with her, along with a number of pals, to keep her company.
"Obviously I'm going to have my friends with me and I'm going to have my family with me ... The thought of how lonely (touring) could be frightens me more than the load of doing a worldwide tour."
Adele also addressed rumours of problems in her relationship with Konecki, insisting stories of a split aren't true.
"We have always been together since we got together, despite what everyone else sometimes says," she explained.
"I am very happy and I think that's the reason that I feel so comfortable that I can write about whatever I want. I got Simon's blessing for that. He was: 'Don't worry about what I'm going to think. This is your thing. Write about whatever you want."'
