Kate Hudson insists forgiveness is the key to her friendly relationships with her exes.

The Almost Famous star was previously married to The Black Crowes frontman Chris Robinson and shares a 12-year-old son with him. She also has son Bingham with ex-fiance Matthew Bellamy. The former couple ended its engagement in 2014, but has stayed friendly for the sake of its son. Kate also has a good rapport with Chris and she explains because they were all able to take responsibility for what went wrong, it has been a relatively smooth experience.

"I think forgiveness is the biggest part of it...," she tells Marie Claire magazine. "I think everybody wants to point fingers. If you are a person who takes responsibility for yourself and your part in it, you have a much better chance of maintaining a nice relationship. It also means that you grow up. A lot of people don't want to grow up because it sucks."

Kate also insists parenting as a single mother has been a work in progress and she tries not to get frustrated when something doesn't work out the way she wants it to.

"I don't try to sugarcoat things," she continues. "I'll say, 'I'm doing the best I can.' I like cooking, I like presenting. I like it to be an experience and (my kids) help me with it, but if they want something after that, I'll be like, 'Look, I'm placing a meal out for you like a king. I can't do everything. I'm going to have to be the OK mom'."

And her role as a working, single mother has made her think about issues on a larger scale and she explains that is why she has thrown her support behind U.S. presidential candidate Hillary Clinton.

"There's so much focus on her likeability," she says. "I want to elect a president to get the job done. When she took the stage, I got incredibly emotional. As a woman, and as a working mom trying to get things done, you find yourself meeting adversity a lot, but you never talk about it because you don't want to bring attention to it. You don't want to go there."
