Salem al-Fakir, a Swedish musician and singer of Syrian origin, performed Coldplay’s Fix You at the Swedish royal wedding of Prince Carl Philip and former model and reality TV star Sofia Hellqvist.
Fakir, 33 years old, was born in Sweden to a Syrian father and Swedish mother.
The soul and pop musician rose into fame following his 2007 album This is Who I Am.
Fakir’s brother, Nassim, 38, is also a famous musician in Sweden and he’s also a comedian and presenter.
Prince Carl Philip married Hellqvist, a former glamor model, in the chapel of the royal palace in Stockholm on Saturday.
Hellqvist had made Swedish media headlines when she won Miss Slitz 2004 after appearing in semi-nude photos.
All of King Carl XVI Gustaf and Queen Silvia's three children have married so-called commoners, or those without a noble rank, with Princess Madeleine marrying banker Christopher O'Neill two years ago.
Sweden is a constitutional monarchy and the king has no political power. Public support for the royal family has waned somewhat in recent years, but remains fairly broad.
Carl Philip, Duke of Varmland, was first in line to the throne at birth, but Sweden changed its succession law in 1980 to make the eldest child - not the eldest male child - heir.
Crown Princess Victoria is now first in line to the throne, followed by her daughter Estelle, born in 2012.
