Sister Sledge are set to perform for Pope Francis.
The iconic music group will sing at global gathering 'The World Meeting of Families 2015' in Philadelphia, America on Saturday (26.09.15) to mark the religious leader's first official visit to the U.S.
The 'Thinking of You' hitmakers will play a special rendition of their hit single 'We Are Family' as the song has become a mantra for peace around the world.
In a statement, they said: ''We are truly honoured to have been asked to perform for His Holiness Pope Francis. The World Meeting of Families is such a special and unique event, which will bring together families from all over the world in a bond of unity, love and solidarity.
''We were thrilled to learn that His Holiness chose our hometown, Philadelphia, to show the entire world the significance of Family, Faith and Love. We firmly stand for and believe in the ideals that Pope Francis will be speaking about, particularly the vital importance of the family, human rights and equality for all.''
The group also believe in the world standing in ''unity''.
The statement continued: ''Our group's legacy of love stems from the expression of sisterhood so triumphantly voiced in one of our most famous songs 'We Are Family'. This message is now as important and fresh as ever. Through life experience we have come to realise that we are all family. Together we must stand in unity as sisters and brothers for the betterment of humankind. Every woman, man and child has the right to receive love.''
The sisters - Debbie, Joni, Kathy and Kim Sledge - are looking forward to being a part of the star-studded event and will be joined by an array of performers that include host Mark Wahlberg, Aretha Franklin, Jim Gaffigan, The Fray and Andrea Bocelli.
