And poignantly, Fleiss told RadarOnline.com she helped Hof celebrate his 72nd birthday just hours before he passed away.
In the Wednesday interview, Fleiss revealed that she'll be taking over one of Hof's brothels in Pahrump, Nevada, and she plans to recruit transgender prostitutes and call it Xanadu!
"I'm going to do the transgender brothel, in one of the buildings he owned," Fleiss explained to RadarOnline.com. "For me, those brothels in Pahrump are easy. I did the deal for him when he bought them.
"The transgenders I know are really hot, hotter than girls. You wouldn't be able to tell the difference. It's the time for that. Nevada may not have been initially receptive but they have to be they can't discriminate. I'm going to call is Xanadu because that sounds kind of mixed gender."
Fleiss said, "I've been talking about opening it with Dennis for the last few months. We could be in business within a month, but I don't know if it will be complicated by his death. I'm sitting down with Dennis' CFO this week."
Fleiss said she was with her close friend Hof to celebrate his birthday on Sunday.
He was found dead on Tuesday at the Love Ranch South brothel in Crystal, NV.
The Nevada-based mogul owned seven legal brothels in the state of Nevada, but Hof was best known for owning the Love Ranch, where Khloe Kardashian's ex-husband Lamar Odom nearly died in 2015.
Jeremy had helped Hof celebrate his birthday, and so had Fleiss.
"On Sunday, I went up to Carson City and surprised him. He was in shock when I showed up, he was so happy," Fleiss, 52, told RadarOnline.com.
"We spent the day together and it was nice. We had quite a few hours alone, then he had a pool party which started at 1 a.m., but I didn't go to it.
"Everything was good until he stood up to walk, and then I really saw he wasn't walking well, you could just tell he wasn't well," recalled Fleiss, known for running a Los Angeles prostitution ring and once being the madam for such celebrity clients as Charlie Sheen.
"With Dennis, I can't say I didn't see his death coming, because of his diabetes. I loved him so much. He was a real friend. Especially to someone like me, a convicted felon and a drug addict with a crazy reputation, yet he couldn't have been a better friend," said Fleiss, who served 20 months in prison on federal tax evasion charges.
"I can only nag him about his health so much and he can only nag me about my drug addiction so much. We both know the issues."
Fleiss said she had urged Hof that day to take better care of himself.
"I was telling him to get to a health retreat, telling him it was life or death. I made him special salads for him to prove health food can taste good, Ninja Salads with 30 different organic vegetables.
"We spent the day together and went for dinner at an Italian place in Carson City.
"We dove back from Carson City to Pahrump together on Sunday and Dennis was making jokes about Ron Jeremy, saying he was senile and he was ready to drop dead, he was making fun of him being ready to drop dead the whole way back."
Fleiss and Hof parted ways on Monday, and on Tuesday, she learned the tragic news that he had died.
"I'm just Dennis' friend, I don't expect anything from him," she said.
"He has a will, everything is in place. It doesn't matter to me if I'm named in it. I'm not expecting anything, if I get zero, I'll still love him just as much. If he left me something I wouldn't feel comfortable with it because my friendship isn't about that."
