The 24-year-old singer and partner Simon Konecki welcomed their child on Friday night, according to an insider who says: "Adele and Simon are ecstatic at their new arrival."
The 'Rolling In The Deep' star announced her pregnancy in June, writing on her official blog: "I'm delighted to announce that Simon and I are expecting our first child together.
"I wanted you to hear the news direct from me. Obviously we're over the moon and very excited but please respect our privacy at this precious time. Yours always, Adele xx"
Adele and charity CEO Simon started dating last summer and moved in together earlier this year. Simon also has a five-year-old daughter with his ex-wife Clary Fisher.
A spokesman for Adele declined to comment on the reports, saying they have no plans to release a statement at this time.
It's proving to be an amazing year for Adele after she was chosen to sing the theme tune for upcoming Bond movie Skyfall.
