"When You Tell the World You're Mine" is a song recorded by Swedish singers Agnes Carlsson and Björn Skifs.

As a tribute to Victoria, Crown Princess of Sweden, Prince Daniel, Duke of Västergötland engaged Elofsson to compose a song that express what we feel when we fall in love with someone.

A part of the revenue from the single is going to the Crown Princess Couple Wedding foundation, to prevent alienation and improve good health among children in Sweden.

Right after the arch bishops speech, Agnes and Björn Skifs performed the song together with the choir of "Storkyrkan" and the orchestra.

It did also enter charts in Finland (#4) Belgium (#150), Netherlands (#124), Denmark (#29), Norway (#28), Austria (#23), Luxembourg (#22), Switzerland (#29), and Germany (#15).
