Just say no to Justin Timberlake.

Janet Jackson’s former stylist, Wayne Scot Lukas, is warning against her appearing in the former *NSYNC singer’s upcoming Apple TV docuseries.

“I’m disappointed because she’s cooler, and she’s smarter, and knows better, so I don’t know if she is going to be in it,” he told Page Six in an exclusive interview on Friday.

“I don’t think she should do it. I think she was treated dirty during this,” he added.

Variety reported earlier this week that Jackson will appear in a four-part docuseries Timberlake is releasing on Apple TV in December. The outlet claimed she will talk about the infamous “wardrobe malfunction” — a phrase Timberlake coined, according to Lukas — she suffered during her Super Bowl XXXVIII halftime show in February 2004.

“The wardrobe malfunction comment was shocking, and I went to fix it, and my attorney said, ‘You can’t speak,’” Lukas recalled.

He told us the “wardrobe malfunction” costs him jobs because, as he put it, “Who wants to hire a stylist who’s known for doing the wardrobe malfunction — especially when it was the most functioning wardrobe in history?”

Lukas claimed Timberlake was supposed to rip off Jackson’s bra to expose her breast, but the world wasn’t supposed to see it. “They keep throwing me under the bus. It’s like, no, honey, it was supposed to rip, grab, [cameras] cut to black and fireworks,” he said of the production.

“Janet was left hanging there, bouncing… and they pushed the blame. They said Justin wasn’t there to rehearse it. Justin rehearsed it several times before we went on the air,” he further claimed.

Lukas told us he wanted to clear the air when he was interviewed for Jackson’s 2022 Lifetime docuseries, but she muzzled him.

“She said, ‘Don’t talk about it. I’m going to handle it.’ And I thought she was… I’m watching the documentary, and I’m lauding how much I love her and at the end, she takes a cellphone and goes, ‘Oh, just get over it.’ That wasn’t what was supposed to happen in her documentary,” he said.

Jackson addressed the halftime show performance in a cellphone video at the end of her doc. In the video, she doubled down on the incident being an accident, and revealed she and Timberlake are “very good friends.”

“Honestly, this whole thing was blown way out of proportion. And, of course, it was an accident that should not have happened, but everyone is looking for someone to blame and that’s got to stop,” Jackson said in the doc.

The “Control” singer further said she and Timberlake had moved on and encouraged “everyone else to do the same.”

Should they address it on Timberlake’s Apple TV doc, Lukas said he hopes they fess up and say, “Guys, we made a plan. It didn’t work as we wanted it to. It went a little messy. We’re sorry we lied for 22 years because you fans have believed in us and trusted us, and you’ve attacked everybody around us as if they were lying.”

“But it was never us. It was covering for celebrity and loving the two of them, because they’re very talented and kind,” Lukas concluded.
