The 28-year-old singer - who already has three-year-old son Angelo with long term partner Simon Konecki - has admitted she has an "ache" in her womb, which tells her she should have another child, although she "won't get pregnant" until her world tour ends next month.
The 'Hello' hitmaker told fans at her concert in Nashville on Saturday (15.10.16): "My son is about to turn four very, very soon.
"I'm starting to get very emotional about it because I feel like once they turn four, they're not really your actual baby anymore.
"So my womb is starting to ache a little bit. It's like, 'Baby, baby, baby. Need a baby, need a baby'. I'm not pregnant. I won't get pregnant until the end of the tour."
The decision comes as a change of heart for the 'Someone Like You' singer, as she told an audience in Minnesota in July that she didn't want to expand her brood.
She said at the time: "I don't think I can have another child. I mean, I can. But I don't think I want two."
But whatever the final decision, the beauty will certainly have the time as it was previously reported she would be taking a long break from touring in order to spend more time with her family.
A source said: "Angelo is the number one priority for Adele. He is the most important thing in her life. She has brought him everywhere with her on tour but as he is starting school next year, he won't be able to join her any more.
"Adele doesn't want to miss a moment of Angelo growing up and it's an easy decision for her to give up touring for him. Right now she is saying she won't do another massive world tour like the current one for another 10 years."
