Kerr, 31, who split from the 'Lord of the Rings' star last October after three years of marriage, said they speak to each other everyday, reported Daily Mirror.
"We speak every day. We're really close, we're going to be a family forever and we both really do love each other. We have genuine love and respect for each other. We're very connected and I feel grateful for that.
"We created something beautiful together and we both remind ourselves how lucky we are to have that. And yeah, it's good. He's a great dad. I'm lucky," she said.
"Everyone goes through challenging periods in their life. That's inevitable and it's part of being human. I feel like it's a daily process to be positive.
"It's something that's a choice and I have different tools, like meditation, even prayer - my grandmother taught me to pray when I was young - and just finding that inner peace," she added.
