Holly Madison has split from Zak Bagans "for good"

Speaking to her 'Girls Next Level' podcast co-host Bridget Marquardt about the recent death of her friend Luke 'The Dingo' Trembath, Holly added: "And then the day after that, Zak and I broke up for good, for good.

"I know we've been very off and on, you guys are probably like, 'You guys broke up last spring, right?' "

Bridget agreed and said: "'Are they together? Are they not together?' We're just like, 'Who knows?'"

Holly continued: "Very off and on.

"Yeah, it was very off and on for the course of the like five-and-a-half years we were together. We were very off and on for the past year, very much. So we broke up and I mean unfollowed on social media, which we've never unfollowed each other before through all the breakups."

Her pal noted: "That's when you know it's serious."

The 45-year-old star - who has children Rainbow, 12, and Forest, eight, with ex-husband Pasquale Rotella - previously praised Zak for his support when she was diagnosed with autism three years ago.

She said: "I'm lucky enough to be dating somebody who just has always kind of understood me and accepts me for who I am, so getting the diagnosis wasn't super shocking to him.

"I am lucky that I haven't had a ton of trouble in recent relationships as far as feeling an intimate emotional connection with somebody."

Holly explained how her diagnosis made her realise why she had struggled to "connect" with people in the past.

She said: "I look back and I just see how I used to have so much trouble connecting with people. I think that played into some of the decisions I made.

"Feeling like I connected with certain people easier and thinking, 'Oh, this must be meant to be because I never connected with anyone before,' kind of a thing, when really, I think it was just being on the spectrum was a difficulty for me."
