Betsey Johnson is known for her circus-like fashion shows — complete with riotously patterned clothes and the designer herself cartwheeling on the runway.

“My upbringing was very positive and clean and pure.” said Johnson, 77.

“I fell in love immediately,” she said.

Warhol and Cale’s bandmates (including Morrison) were there, yet it never occurred to Johnson to invite her family.

The couple split, Cale got clean, and they remain friendly: “He was my favorite husband,” Johnson said.

“I was so out to lunch with men and relationships,” she said.

There was “Joe,” whom she describes as “icy.” After their daughter, Lulu, was born, Johnson moved out.

“Later, I got a call from a woman who said she was Joe’s wife.

She wanted me to support Joe, her and their four children,” she said.

A frightened Johnson was thrown in a van by two men, who were flanked by cops with guns drawn.

When a woman entered, asking questions in a foreign language and coming at her with a needle, Johnson went berserk.

The woman left, and Johnson escaped when another worker brought her outside for some air — only to be caught by police and returned.

“I had ­indeed been inoculated!” she said.

“I was shocked myself because I never connected with the traditional fashion world,” Johnson said.

Johnson — now based in Malibu — is the creative director.

“I am dying to meet a guy!” she said.
