There have now been two Mamma Mia! films - and we are still no closer to finding out who the daddy is.
The entire plot of the first movie, based on the songs of ABBA and released in 2008, revolves around bride-to-be Sophie Sheridan trying to find out which man is her biological father.
She invites all three potential daddies, Irish-American architect Sam Carmichael, Swedish travel writer Bill Anderson and British banker Harry Bright, to her wedding to find out who should give her away.
