The former couple said in their statement: ‘With absolute love and respect, we decided to separate as a couple earlier this year.

‘To give our family the best opportunity to adjust, we wanted to keep this a private matter before sharing it with the public. We are and will always be united in our support of each other and our family.’  

‘Friends have been expecting them to split for a while now,’ said a source to UsWeekly. They are just too different. Josh is a normal guy and Fergie wants to have this Hollywood celebrity lifestyle. They just grew apart.’
