So far, Adele has kept her baby boy's name a closely guarded secret.

On an outing Monday to a favorite baby boutique, Adele – who won a Golden Globe for her James Bond tune "Skyfall" and is scheduled to perform at the Oscars – was spotted wearing a gold necklace featuring the name "Angelo."

Could that be her angel? The singer, who has referred to him as a "little Peanut," won't likely say.

"I am not sharing his name at the moment. It is very personal to me," she told PEOPLE. "I am enjoying him on my own."
