The 'Rolling In the Deep' singer and boyfriend Simon Konecki welcomed their first child together in October, but have so far revealed only the sex of the newborn.
Adele made her first post-baby appearance at the Golden Globe Awards on Sunday (January 13), where she won an award for her song 'Skyfall'.
After the win, the singer opened up to People about motherhood, admitting: "I am exhausted, that's how motherhood changed me. I have eczema from boiling bottles."
The singer added: "I am not sharing his name at the moment. It is very personal to me. I am enjoying him on my own."
In a bid to keep her son's name a secret, the performer has reportedly refused to register his birth, facing a fine for failing to do so.
