Fox did not reveal any of the co-stars she developed feelings for, nor did she admit to any cheating during the sit-down interview with podcast host Alexandra Cooper.

However, the “Jennifer’s Body” star confessed, “I was not a great girlfriend to Brian, I will be honest.”

She said Green, 50, wasn’t great to her “either” but recognized her age had a lot to do with their issues.

Fox began dating her ex-husband when she was just 18 in 2004. She then married the “Beverly Hills, 90210” alum — who is nearly 13 years her senior — six years later when she was 24.

“I was young and really should not have been in a relationship of that level of commitment and that magnitude,” Fox reflected on “Call Her Daddy.”

The “Holiday in the Sun” actress said she decided to get married because she was “so unaware” of her feelings, adding, “Most of my growth and awareness came after childbirth.”

Fox and Green share three children: Noah, 11, Bodhi, 9, and Journey 6. They officially split in early 2020 after 10 years of marriage.

Fox said she did not stay single for long because she began dating Machine Gun Kelly just weeks later.

The “Pretty Boys Are Poisonous” author said, “I thought for a minute when I got divorced that that’s what I was going to do, and I was single for, like, three weeks.”

Fox and Kelly, 33, got engaged in January 2022 after two years together, but the “Expend4bles” actress confirmed on “Call Her Daddy” that the on-again, off-again couple ended their engagement.

However, she declined to provide further clarity on their current status, saying, “I think as of now, I don’t have a comment on the status of the relationship per se.”
