Adele's family were reportedly kept in the dark about her rumoured recent wedding.
The 28-year-old singer referred to her long-term partner Simon Konecki in her speech at the Grammy Awards earlier this month, while the 42-year-old charity boss was seen sporting a gold band on his wedding finger at the BRIT Awards.
However, following reports the couple - who have four-year-old son Angelo together - tied the knot in Los Angeles in a low key ceremony at Christmas, the 'Hello' singer's loved ones are said to be stunned and a little "disappointed" to have been kept in the dark.
A source told the Sunday Mirror newspaper: "Adele and Simon have a big family but some of those closest to them weren't aware of any impending wedding and were shocked to hear one might have gone ahead.
"They feel disappointed if it's true. They understand they're a private couple but are surprised to see them potentially cut out their loved ones."
And a source claimed some members of the family still believe there will be some sort of ceremony or celebration in the UK later this summer.
Adele has yet to confirm whether or not they have tied the knot.
It was previously reported the couple had planned to marry over Christmas so Simon's nine-year-old daughter from a previous relationship could be there.
A source said: "The plan is to marry in Los Angeles. The wedding will be in one of the school holidays so Simon's daughter can attend. It's looking like it will be Christmas, but they want to keep details under wraps.
"Adele is not even wearing her engagement ring. They're a private couple and only want their nearest and dearest there."
The couple - who have been together for five years - got engaged in October during Adele's world tour.
