Jessie Cave, the actress who played Lavender Brown in the final three “Harry Potter” films, revealed she’s raking in a significant income from her OnlyFans gig.

“I’ve earned more, easily, than my entire acting career within one year,” Cave, 39, told the Times in a recent interview.

Brown — who joined the platform last year — told the outlet that in one day, she made £15,000, which equates to just over $20,000.

The actress admitted that she charges subscribers $6 a month, but takes in more for “paid-for messages” on the platform — and that in the past year, the cash has “saved” her.

“I thought I’d make five grand, be on it for a few months and it would buy me time to work out what we’re going to do,” she told the outlet. “But it’s now been over a year and a half and it’s genuinely saved our lives.”

Cave further divulged that she had arrived at “a point of complete desperation” amid a dearth of audition opportunities.

The actress said what people think of as normal jobs don’t make sense for her — but she and longtime partner Alfie Brown, with whom she shares four children, needed additional income.

“I couldn’t go and, say, work in a supermarket because I can’t afford the childcare, and also I don’t want people shouting ‘Harry Potter’ spells at me as I work at Tesco,” she explained.

“I could retrain but I can’t afford to do a degree,” she added. “I had a breakdown and I thought, that’s it with acting, I give up. But also we have no money.”

Cave divulged to the news outlet that she sometimes dresses as Lavender Brown for fans and does “hair content” for fetishists — but noted that she’s always fully clothed.

“My rule is the hair is the main character,” she shared, noting, “That’s how I justify it. It’s literally about hair: the texture of hair. The fetish. It’s very, very niche.”

Cave boasted of her hair’s length, too, saying it’s “down to [her] vagina.” She added, “I could trim it but the truth is, the weirder the better.”

The actress also explained that she’s enjoyed the change.

“For so long I’ve just been this quirky figure,” she told the Times. “After having four kids and feeling invisible for so long that was really appealing to me.”
