As long as someone’s footing the bill!

Lily Allen says her OnlyFans followers most often request pictures of her feet in socks — sometimes dirty, sometimes clean — or ask to choose the color of her toenail polish.

The Brit singer started an account on the smut streaming site last year after realizing that others online were cashing in on her tootsies, and deciding she’s rather have the cash herself.

But in a new interview with Interview magazine, Allen revealed what her foot-fiend followers usually crave.

“They want dirty soles, white socks, like schoolgirl socks or ankle socks, some clean, some dirty,” she told Interview’s editor-in-chief Mel Ottenberg, “White socks in Mary Jane shoes. Stepping in food. Toe spreading, because that’s what happens when you’re climaxing.”

The “LDN” singer — who has a new album, West End Girl, out now — said that, in fact, many foot fans are as interesting in the shoes as the feet themselves.

Meanwhile, she said that, while some feet freaks like to her see her rubbing oil on them, many are fixated on the nails.

“That’s the other thing they pay money for—they get to choose the color… Some people want white. Some people want dark red. Some people want bright red,” she said, I would never let anyone ask for a green or a blue or something.”

But she said some requests get a little too weird.

“I tend to just ignore it and move on,” she said.
