The `Rolling In The Deep` singer - who up until now has kept her baby boy`s name a secret since his birth last October - has been spotted wearing a gold necklace with the name Angelo while out shopping in Los Angeles.
A source close to the 24-year-old star, who is engaged to charity worker Simon Konecki - confirmed the child`s moniker is correct and told The Sun newspaper: "Those close to Adele have been told the baby is calledAngelo. We`re not sure of the significance of the name.
"She`s wanted to keep it quiet but it was always going to come out sooner or later. "Wearing an Angelo necklace not only backs up what is being said, it suggests she`s not worried about people finding out."
Adele refused to reveal her first child`s name at the Golden Globes - where she made her first formal public appearance since giving birth to her baby to pick up the Best Song prize for her theme to James Bond film `Skyfall` - earlier this month because she was "not ready".
When asked the name of her baby, she replied: "It`s too personal and intimate. I`m not ready." But she added: "I just call him Little Peanut."
The British star - who is tipped to win an Oscar for Best Song next month - admitted motherhood has made her "exhausted", and insists giving birth to the little one so close to the movie`s release date was "bad timing".
She added: "I am exhausted, that`s how it`s changed me. That and eczema from boiling bottles. "I had my child about two weeks before the `Skyfall` film came out. So it was bad timing."
