Gwyneth Paltrow's lifestyle site Goop has taken its eyebrow-raising product selection to a new level … leather lingerie.
The website is selling Fifty Shades of Grey-style leather bras and knickers that Goop calls "not practical, which is the point".
But Paltrow's idea of sexy does not come cheap — the Fleet Ilya nude leather bra costs $US312 ($NZ453), and a matching leather G-string is $US318 ($NZ652), reports news.com.au.
Page Six reports the nude-coloured bra and underwear set are made in England from "saddle leather" and are "shocking, sexy, and just the right amount of subversive", according to goop.com.
Goop is even stocking a "studded handle flogger" for $US240 ($NZ348), which it says is "perfect for play" and features a studded handle and 16 leather tails, according to the New York Post.
According to Goop: "The edgy studs, while aesthetically pleasing, serve a functional purpose — making it extra comfortable to grip. So, you might imagine it's pleasing in other ways too."
Paltrow is no stranger to pushing boundaries with the products she stocks on the much-mocked lifestyle site, from a crystal-infused water bottle to so-called 'vagina eggs'.
The Oscar-winner has previously suggested her readers buy a $15,000 gold vibrator and conduct an at-home coffee enema.
The latest racy products added to Goop's online store comes after Paltrow hosted the star-studded "In Goop Health" summit in New York.
At the summit, Paltrow, 46, touched on some of the criticisms of Goop — her much-mocked modern lifestyle brand — which has been criticised for promoting expensive and slightly odd wellness and fashion products.
"Sometimes at Goop, we get pushback about our non-toxic products that we make and that we sell not being on par with the price points of drugstore products," Paltrow said at the summit, according to Fortune.
Goop, which is expanding with a new Netflix docuseries this year, has been accused in the past of false claims and recently paid out $US145,000 ($NZ210,815) in civil penalties to resolve allegations relating to so-called "vagina eggs".
Despite recommending nutritional supplements and various exercises and diets, Paltrow denies claims that Goop offers a gold star of approval.
"When we were young and not even monetising the business and just sort of creating content, we didn't necessarily understand anything about claims. We just thought, 'Oh, this is a cool alternative modality, let's write about it,'" Paltrow said, according to the New York Post.
"Of course we've made some mistakes along the way, but we've never been prescriptive. We've never said, 'You should try this,' or 'This works.' We're just saying, 'Wow, this is interesting, let's have a Q and A with this person who practices this.'
"And then that somehow gets translated into, 'Gwyneth says you should do this.'"
