Adele sent a hand-written note to Elton John to apologise for missing his wedding.
The 26-year-old singer penned the note from her, her partner Simon Konecki and their two-year-old son Angelo, to say sorry for not making it to the music legend's marriage to longtime partner David Furnish yesterday in Windsor, south east England, and to wish the couple good luck on their big day.
"Biggest congratulations my loves. Have a wonderful day. I'm sorry we are not there. See you in 2015. Love Adele, Simon and Angelo. x,” she wrote.
Elton posted a picture of the letter - which Adele penned on headed note paper from floral designer Rob Van Helden, who also attended the nuptials - on his Instagram account alongside several other congratulatory cards sent to the couple.
He added the caption: "The perfect end to the perfect day. So many kind thoughts and wishes. #ShareTheLove (sic)"
The image was one of 11 Elton posted on his newly-created social networking account on which he shared memorable pictures of his and David's wedding day with their fans.
Other photographs included one of the pair's wedding menu which featured wild mushroom soup with truffle cream to start, followed by a beef rib and caramelised onion pie and then a warm chocolate pudding with vanilla ice cream for dessert.
Elton also posted an adorable image of the couple's sons', Zachary, three, and 23-month-old Elijah, shiny, polished shoes in front of a roaring fire the night before the wedding, where they acted as ring bearers for their parents.
The 'Your Song' hitmaker added the caption: "Our little ring bearers are fast asleep, and their shoes are polished and ready for tomorrow's celebration.@DavidFurnish #ShareTheLove (sic)"
While Adele didn't make the spectacle, several other stars had some festive fun at the bash including David and Victoria Beckham and their four children, Brooklyn, 15, Romeo, 12, Cruz, nine, and Harper, three, as well as Ed Sheeran, David Walliams and his wife Lara Stone, and Elizabeth Hurley and her 12-year-old son Damian.
