Prince Carl Philip himself has allegedly been in touch with Sweden's most famous DJ, to ask him to provide the evening entertainment at his wedding to former reality television star Sofia Hellqvist.
"I know nothing more than that he will play," his mother Anki Lidén told Swedish tabloid Aftonbladet.
Avicii, whose real name is Tim Bergling, lives in a luxury house in Los Angeles, but hails from Stockholm and is a regular visitor to his home country.
With hits including 'Wake Me Up' and 'Hey Brother', he has a huge setlist to choose from should the rumours about his performance turn out to be true.
However Aftonbladet's coverage of the upcoming royal wedding has not always been accurate. The paper printed the couple's supposed guest list last month, before hastily retracting it after Royal Palace press officer Margareta Thorgren told Swedish media magazine Resumé via text message that the list was inaccurate.
"They have probably compiled this list based on previous guest lists. We have not published any guest lists," she said.
Several members of the Swedish royal family are rumoured to be big Avicii fans and the star's 'Hey Brother' track has even been performed outside the Royal Palace by The Royal Swedish Army Band
Prince Philip has dated Sofia Hellqvist since January 2013. She is a former fashion model who famously participated in the scandalous TV series Paradise Hotel.
The couple met in 2009 at a club in Stockholm's posh Stureplan district. They have lived together on the island of Djurgården since 2011.
The wedding schedule will get underway on Friday June 12th, when the couple's friends and family will be invited to a private evening dinner, a statement from the court revealed last month.
The following day, Saturday June 13th, a legally binding church service will take place in the Royal Chapel at the Royal Palace in Stockholm, starting at 4.30pm.
An evening banquet followed by dancing is set to take place in Karl XI's Gallery in the Royal Palace.
