Arnold Schwarzenegger called Miley Cyrus, the former girlfriend of his son, Patrick, a "fantastic person." The 67-year-old talked about the split between Patrick and Cyrus in an interview with Howard Stern on his SiriusXM radio show on Wednesday.

“[Miley] has this career side where she has to be a little bit out there and maybe is a little bit different because she grew up in a music family. So what? It didn’t bother me. I think Patrick had a wonderful experience, he had a great relationship and then the whole thing eventually fell apart,” Schwarzenegger reportedly said. Cyrus and Patrick reportedly split with each other in May and since then there has been no hope of reconciliation between the two.

“When I did meet Miley Cyrus -- when she came up to Sun Valley skiing during our holidays -- I found out that she is a fantastic person,” Schwarzenegger reportedly continued saying. “We had little kids in the house. She went out every day to buy gifts for them. She played with them, really, sincerely, like two hours at a time would go out in the snow with them.”

Since their split, Patrick has bagged his first film role in “Midnight Sun” alongside Bella Thorne, while Cyrus has moved on in her music career, and is also rumored to be dating Victoria’s Secret model Stella Maxwell.

Schwarzenegger also reportedly spoke out about his 17-year-old love child Joseph Baena.

"He's terrific and he totally understands the situation. So, it all has worked out. ... It's a very tough situation for him. It's a very tough situation for my kids, very tough situation for my family. It was tough for everybody. But it has happened and now we have to figure it out, right?” he said.

Schwarzenegger also opened up about his split with Maria Shriver, with whom he has four children -- Katherine, 25, Christina, 23, Patrick, 21, and Christopher, 17. The two ended their marriage after the news broke out in 2011 that the “Terminator Genisys” star had fathered a love child with his former housekeeper, Mildred Baena.

“I had personal setbacks, but this was without any doubt the biggest setback and the biggest failure," Schwarzenegger reportedly said. "Without any doubt. And not only failure, but you really feel like, 'I am to blame for it. It was me that screwed up.' And you can't point the finger at anyone else. So yeah, I was disappointed at it, but it's always easy to be smart in hindsight.”
