David Bowie offered a young Michael Jackson drugs: new Janet doc

Growing up with the Jackson 5 for brothers, Janet Jackson got used to partying with celebrities from a very young age.

After the Jackson family moved from a two-bedroom house in Gary, Indiana, to a three-acre home in Los Angeles in 1971, they regularly played host to stars like Diana Ross, Bing Crosby, Marvin Gaye and Sammy Davis Jr.

The new documentary “Janet Jackson” — which premieres on Lifetime and A&E in two parts over Friday and Saturday nights — revisits a night when one such Starman showed up with his own party favors.

“I remember one of the parties that we had, [David] Bowie came,” Janet Jackson said of her family’s brush with Ziggy Stardust. “And I guess to get away from everyone, he was looking for a little room.”

As the late rock legend went in search of a private spot to indulge, he ran into two of the Jackson brothers.

“Michael and I are sitting in one of the other rooms away from the party,” said Randy Jackson. “So Bowie walks in and … he offered us some of what he was doing to get high.

“We just looked at each other. We were like, ‘No.’ We didn’t know what it was, but it was like, ‘Nah, no thank you.’”

But the Jacksons weren’t so welcome by everyone in the affluent white neighborhood of Encino.

“They had this petition going around so that we wouldn’t be in the neighborhood,” said Janet.

“I remember walking down the street and being called the N word, someone driving by and yelling it out … [being] told to go back home to the country, feeling it at school with some of the teachers and some of the kids touching your hair ’cause your hair was different from theirs.”

Still, under the strict rule of their father Joe Jackson, the Jackson kids — with Janet being the youngest of nine — thrived in the face of that racism.

“My brothers and sisters would always tell me why my father was so strict,” said Janet, who was managed by her late dad early in her career.

In fact, after her brothers fired their father as their manager, Joe Jackson set out to make Janet an even bigger star than Michael — though she would eventually strike out on her own with her 1986 breakthrough “Control.”

Still, Janet acknowledges that her dad’s determination on behalf of his children was foundational. “It was because of my father that I’ve had the career that I’ve had,” she added.
