A mum who says she's earned more than £100,000 selling pictures of her feet online has issued a warning to Lily Allen.

The Smile singer, who is now teetotal and clean living, last week revealed she'd joined OnlyFans with plans to flog images of her feet to fans. She's charging £8 a month to see photos of her manicured tootsies, but won't be sharing any other part of her body.

Mum of three Lizzy Groombridge is well placed to comment on the 39-year-old star's unexpected career move. The 30-year-old has earned more than $150,000 (around £118,000) selling images of her size nine feet. The 'Green giant', as Lizzy is sometimes known, has attracted attention thanks to her domineering 6ft 3in frame and side hustle.

While she supports Lily's decision to enter the world of feet pics, she offered a few words of wisdom.

"I've always been a fan of her music and I'm in support of her decision, [but she must] continue to be honest about her journey," Lizzy said. "[Otherwise], her younger fan base may be led into a false sense of obtaining easy money.

"It's a personal choice; I know how younger people have looked up to me in the past and thought it can be a good money maker. But it's not that easy, for her, she's got the backing of being who she is. It's [hard] just to be successful this way and others should not be led to think so. At the end of the day, we don't live our lives to appease everyone else."

The mum says Lily Allen needs to be careful with her new venture

The mum applauded Allen for 'maximising her earnings' and 'securing her own future' -while also bolstering the foot fetish community. However, she says it can be draining working in the public eye, and Allen must be considerate of the influence she has on her fan base.

"I don't regret it, but it comes with a huge amount of sacrifice," Lizzy added. "At the end of the day, it's down to the audience and she's worked hard to be out there. If she finds another way to monetise herself, then well done to her. I don’t judge her and I think it's good for her."

The couple rake in thousands every month

Lizzy and her 4ft 11in girlfriend Candie Dixon, make around £5,000 a month on OnlyFans. Despite haters criticising the pair's contrasting height, they have appealed to a particular fetish: "an imaginary gigantic woman."

The couple have received custom requests from fans to put on dirty white socks on a person's face after walking around her house as a 'giantess'. "I don't meet fans, just make content with someone trusted for them to buy," she explained.

"I won't do any requests that are too dark or inappropriate, as there are some people who overstep the line. My most popular content is lift-and-carry point of view, humiliation, crushing and also shrinking roleplay, such as standing on toy cars and food."
