She made a shocking revelation on her reality TV show on Sunday night, claiming she suffered a miscarriage during the filming of the programme.
But now sources close to Lindsay Lohan have sensationally claimed that her alleged miscarriage was actually fake and she simply made it up in order to garner sympathy from viewers and distract from her unprofessional behaviour while making the show.
A source told RadarOnline: 'She absolutely made it up.'
MailOnline has contacted Lindsay's representative for comment.
The insider continued: 'Lindsay was never pregnant during filming the reality show for OWN, or in the months after.
'Lindsay knew she was being perceived as a total slacker, not showing up on time for photo shoots, call times and refusing to shoot. So this is what Lindsay does. She lies!
'Her family and friends had no clue about her "pregnancy" and subsequent miscarriage. Lindsay is once again her own worst enemy.'
Lindsay said the miscarriage was the reason she took a couple of weeks off from filming the programme for Oprah Winfrey's OWN network.
The 27-year-old had previously hit the headlines for the break, which held up production on Lindsay.
Speaking at the end of the final episode of her show on Sunday night, she said: 'No one knows this, I had a miscarriage for those two weeks that I took off. It's a very long story.'
Lindsay did not reveal the identity of the father when she made the confession.
However, a second source told Radar: Lindsay has continued to smoke through-out this entire series and has admitted to relapsing and drinking alcohol.
'Don't forget there have been multiple media reports that she fell off the wagon months ago. Quite simply, Lindsay never acted like someone who was pregnant. It's just sad that anything that comes out of her mouth is considered to be a lie.'
However, a new KODE magazine article claims the star thought she may have been pregnant by her 'married lover' when she was at Coachella, on April 14.
'It is unclear if this is the same pregnancy she talked about on her reality TV show.
