That's one way to mend a broken heart, we guess!

Ashton Kutcher opened up about his painful split from ex Demi Moore on Dax Shepard's Armchair Expert podcast, and the actor revealed that he retreated into nature when they made the decision to get a divorce.

"Right after I got divorced, I went to the mountains for a week by myself. I did no food, no drink — just water and tea. I took all my computers away, my phone, my everything. I was there by myself, so there was no talking. I just had a notepad, a pen and water and tea — for a week," he explained.

He also made amends with his past, and wrote a letter to all his exes that he felt he had lingering resentments with.

"I wrote down every single relationship that I had where I felt like there was some grudge or some anything, regret, anything. And I wrote letters to every single person, and on day seven, I typed them all out and then sent them,” he revealed.

If we were Demi, we'd just want him to shut his trap about it!
