Arnold Schwarzenegger has fond memories of his son Patrick Schwarzenegger's ex-girlfriend Miley Cyrus

Quizzed on the best thing about Patrick dating Miley, the Terminator actor told Watch What Happens Live With Andy Cohen: "The best was that she's a wonderful, wonderful girl and human being. Very, very talented. She came up to Sun Valley when we were skiing up there and she was just such a wonderful houseguest and everything like that.

"We all just loved her."

Schwarzenegger insists that there were no downsides to Patrick, 31, dating such a high-profile star.

The 77-year-old actor said: "She was just a really good, good person and fun to hang out with."

Arnie continued: "I'm sorry it didn't work out. But Patrick, in the meantime, found another girl that he got engaged with and he's getting married to in September."

Patrick played the role of Saxon Ratliff in the third season of the acclaimed TV series The White Lotus and Arnie revealed his shock at seeing his son strip nude for a scene in the HBO show.

Speaking in a joint interview for Variety's Actors on Actors series, the True Lies star said: "I couldn't believe [it].

"I said to myself, 'I'm watching your show, and I'm watching your butt sticking out there.' And all of a sudden, I see the weenie.

"What is going on here? This is crazy."

However, the movie legend soon reminded himself that he had appeared in precious little clothing for some of his most memorable roles.

Arnie said: "Then I said to myself, 'Well, Arnold, hello. You did the same thing in Conan and Terminator, so don't complain about it.'

"But it was a shock to me that you were following my footsteps so closely."

Patrick previously admitted that he was frustrated that some assumed that he had landed a part in The White Lotus because of his famous father.

He told The Sunday Times newspaper: "I know there are people who'll say I only got this role because of who my dad is.

"They're not seeing that I've had 10 years of acting classes, put on (high) school plays every week, worked on my characters for hours on end or the hundreds of rejected auditions I've been on."
