His ex-wife and rumoured current lover, Sarah Ferguson, also shared her birthday wishes.
"Happy 60th Birthday to Andrew," she wrote.
But again, followers were not so keen to share her joy.
"I admire your loyalty to him and his to you... but... out of loyalty to your daughters and women, best to be quiet," one wrote.
Another added: "You’ve stayed celebrating him while promoting human trafficking issues. He’s been at the very least a benefiter of human traffickers and a friend of abusers. This is a time for humility."
A message on the royal family's Instagram read: "The wedding of HRH Princess Beatrice of York and Mr. Edoardo Mapelli Mozzi will take place on Friday 29 May 2020.
"The couple became engaged in Italy in September 2019.
"The Queen has kindly given permission for the ceremony to take place at The Chapel Royal, St James’s Palace.
"The ceremony will be followed by a private reception, given by The Queen, in the gardens of Buckingham Palace."
The news of the date was met by excitement and ribbing.
One person wrote: "29th May might be a bit hot for the father of the bride, seeing as the poor fellow struggles to sweat."
Another wrote: "I'm So Excited, ❤️ a Royal Wedding."
The news was delayed because of their father's fateful interview with the BBC concerning the Jeffrey Epstein sex scandal.
Princess Beatrice and Princess Eugenie are said to be 'devastated' with a source told The Daily Express they are “deeply distressed.”
According to the publication both Princess Eugenie and Beatrice have been keeping a low profile since Prince Andrew withdrew from his duties from the royal family last week.
“It has become clear to me over the last few days that the circumstances relating to my former association with Jeffrey Epstein has become a major disruption to my family’s work and the valuable work going on in the many organisations and charities that I am proud to support," he said in a statement.
“Therefore, I have asked Her Majesty if I may step back from public duties for the foreseeable future, and she has given her permission," he added.
"I continue to unequivocally regret my ill-judged association with Jeffrey Epstein.
“His suicide has left many unanswered questions, particularly for his victims, and I deeply sympathise with everyone who has been affected and wants some form of closure.”
Sources also claimed that by undertaking the interview: “Andrew was fighting not just for his survival, but for all their survival.”
