Adele has given birth to a baby boy, according to reports.
The Grammy winner, 24, is thought to have had her first child with boyfriend Simon Konecki on Friday night.
She has so far not commented on her blog or her Twitter account, and a spokesman declined to comment.
However, many have taken to Twitter to congratulate the couple.
The voice behind the latest James Bond theme, Adele announced her pregnancy on her official website in June, and said she and Mr Konecki were “over the moon” at the news.
The June post telling of her baby joy is the singer’s most recent contribution on her blog.
She wrote: “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.”
The London-born singer had the world’s biggest-selling album last year with 21, which sold more than 17 million copies – with four million sold in the UK alone.
It earned her six Grammys, two Brits and two Ivor Novello awards, and is thought to contain a series of songs written about her ex-boyfriend.
She reportedly met Mr Konecki, CEO of water charity Drop4Drop, in summer 2011.
The couple began dating, but only confirmed their relationship in January after being introduced by mutual friends.
The singer was forced to deny speculation they had tied the knot in August amid reports Simon had quietly popped the question on her 24th birthday in May.
She wrote on twitter: "I'm not engaged blah blah".
A spokesperson for Adele refused to confirm the arrival of her baby boy and would only say: "We are not releasing a statement at this time. No comment."
