Guy Pearce's ex-wife was the "greatest love of [his] life".

The 57-year-old actor was married to Kate Mestitz between 1997 and 2015, and Guy has explained that their relationship still means a lot to him - even though he's "moved on from her".

Guy - who has Monte, eight, with his long-term partner Carice van Houten - told the Guardian newspaper: "My ex-wife, Kate, was the greatest love of my life, but I've moved on from her now and the greatest love of my life is my child, Monte."

The movie star was "devastated" by his divorce and Guy initially felt that he was to blame for their break-up.

He said: "I felt like I messed up my marriage. I don't feel that way any more, but at the time I was devastated."

The actor's experience of parenthood has made him even more appreciative of his own mom and dad.

Asked what he owes his parents, Guy said: "Absolute gratitude, which I am realising more and more as my son gets older."

Guy announced his split from Kate in 2015, explaining that the time had come for them "to part ways".

The actor - who has known Kate since they were both children - said in a statement: "Kate and I will always love and support one another and be the best of friends. No one knows me like Kate does, and we'll forever be appreciative of our mutual respect.

"We've both grown enormously through our relationship, but sadly, the time has come to part ways."

Guy also confirmed the news on social media.

He wrote on X at the time: "Rumours r true I'm afraid - Kate and I parted ways back in Jan. Sorry 2 be boring but we couldn't be closer. We'll love each other 4 ever xx (sic)"
