She said: 'As with most relationships, we are friends first.

“Our relationship and all the problems we had were never arguments. Disagreeing on things was never our problem.

'This sounds cliché, but I really just want peace, I really do.

“This has been a very difficult year, with so many difficult things in my personal life and so much criticism.”
