One year on and the couple were still blissfully happy – with "the same energy as before, but with more depth". Ashton revealed all to a US magazine, explaining that the secret to their success was a lack of arguing.
"We have frustrations, like every relationship. It's just the way we deal with them." He added: "Demi told me once, 'When you're right, that's all you get to be.'
"And for some reason, that made sense to me... We had one argument in the first three months of dating, and since then we haven't had any. We deal with issues before they become arguments.
"I've never tried to change my wife, and she has never tried to change me. It does bad things when you turn the other person into the ball and chain in your life."
