Mark Owen is getting married.
The Take That star will wed long-term girlfriend Emma Ferguson - mother of his two children, Elwood Jack, three, and nine-month-old Willow Rose - in November at a secret venue in Scotland.
The couple have sent out save-the-date invites and guests - who will include Mark's bandmates Gary Barlow, Howard Donald and Jason Orange - have been told to meet at a pick-up point, where they will be taken to the mystery location.
A source said: "They have picked a venue that's special to them. But they want it to be a surprise for their family and friends right up until the big day. Everyone has been trying to guess where it is, but not even Gary, Howard or Jason know where they will be.
"All they know is they have a night off and won't be expected to provide the entertainment for the night."
Mark, 37, first proposed to Emma in 2006 but delayed their nuptials due to the birth of their two children as well as Mark's commitments with Take That.
The source added: "Mark and Emma have been planning their wedding for sometime and have put a lot of thought into what they wanted. They already have two beautiful children so getting married is just the icing on the cake for their family."
It is thought the couple will only invite around 50 guests. Mark's former Take That bandmate and close friend Robbie Williams is expected to attend.
