It has since been reported that Adele and Simon tied the knot late last year while they were in the US. MailOnline has contacted a spokesperson for Adele for comment.
Known for remaining tight-lipped about her personal life, Adele only announced her marriage to the charity founder after referring to him as her "husband" while collecting her Album of the Year Grammy award earlier this month.
Taking to the stage at the Staples Center in Los Angeles the hitmaker had said to the audience: "Grammys, I appreciate it, the Academy, I love you, my manager, my husband and my son - you're the only reason I do it."
The Rumour Has It singer, 28, met 42-year-old Simon, who started Drop4Drop, back in 2011 - and the pair share four-year-old son Angelo together.
