Jasmin - who shot to fame in the '90s after breaking the original world gang bang record - said that Lily is 'lower than low' for pretending to be pregnant.
'She's as bad as Belle Gibson,' said Jasmin, referring to the notorious cancer scammer who is currently the subject of Netflix's Apple Cider Vinegar.
'This is the type of person that would fake cancer, that's how low she would go,' the 52-year-old continued.
'There are millions of people who cannot have children that go through IVF, and it's sort of a joke on them. It's not role playing, it's just flat out desperation.'
Jasmin also said that she didn't believe Lily was being sincere when she broke down in tears after bedding 100 men in a single night.
'There's nothing realistic about this hundred guys or whatever amount of guys we're up to now. There was nothing realistic about her fake tears,' she said.
'Your sham's up. It's not the same as it was back then when we were doing these things. It's all just 'What else can I do for more clicks?''
'90s porn legend Jasmin St. Claire (left) has come out swinging against OnlyFans star Lily Phillips (right) over her pregnancy publicity stunt
Jasmin, 52, shot to infamy in 1996 after starring in The World's Biggest Gang Bang II - an X-rated film which saw her romp with 300 men in 24 hours.
Her scathing comments come after Lily falsely claimed to be pregnant - only to admit days later that it was a stunt.
The British model, 23, had shared two separate 'pregnancy' posts on Instagram, including a brief video where she was seen cradling a baby bump.
'Baby Phillips coming 2025,' she captioned it.
Additionally, she posted a photo of two pregnancy tests, one of which appeared positive while the other, with a faint second line, seemed inconclusive.
These posts came shortly after her former friend and fellow OnlyFans performer Bonnie Blue hinted that she was experiencing unusual 'cravings,' leading to speculation that she was also pregnant.
However, both women have since clarified that they are not with child.
A source close to Lily confirmed to news.com.au that her pregnancy announcement was indeed part of her adult content, and not a legitimate pregnancy.

'Lily's career choice... involves role play, acting, and storylines to follow trending categories and hit target audiences in the adult industry,' the source said in a statement.
DailyMail.com has contacted Lily for comment.
Jasmin previously slammed Lily shortly after the English OnlyFans star went viral for sleeping with 100 men in one night.
Having been there, done that decades earlier, the brunette didn't mince words when asked by DailyMail.com to share her thoughts on Lily's antics.
'She's not doing anything new,' sniffed Jasmin, before adding, 'And in 20 years from now, I can guarantee you, nobody will remember her.'
Jasmin, who found fame in professional wrestling after leaving porn, also warned Lily to be wary of sexually transmitted diseases.

Jasmin previously blasted Lily for crying after her 100-man orgy, going as far as to accuse the English model of putting on 'crocodile tears' for the camera
'I get a lot of OnlyFans girls on my podcast... and the one common story is all of the different STD outbreaks in the business,' she shared.
'Like, I've never heard of half this stuff in my life. I'm like, holy s**t. Can a doctor from India cure that? Like, seriously, because these are some weird things.'
Jasmin also blasted Lily for crying after her 100-man orgy, going as far as to accuse the English model of putting on 'crocodile tears' for the camera.
'Then you go and you start crying about your mental health and wearing it like some perverse badge of honor, because as we know, people use mental health and having issues as a trend,' she said.

Jasmin became a tabloid media sensation in 1996 when she broke Annabel Chong's group sex record.
The film was advertised as having Jasmin engage in sex acts with 300 men, although it's unclear exactly how many she was really with.
She made multiple appearances on Howard Stern and Jerry Springer at the time, before leaving adult entertainment to become a pro-wrestling star in ECW and XPW.
Jasmin also acted in a handful of mainstream comedy films and now hosts her own podcast called Krazy Train.
