Lindsay Lohan dropped a bombshell on her “Lindsay” viewers Sunday night, admitting to a secret pregnancy and subsequent miscarriage while filming the OWN network docuseries.

When prompted to discuss her experience watching the reality show on the series finale, Lohan admitted to crying over the footage of her life before revealing to producers that she suffered a miscarriage during a period of days when she refused to film. “When a camera's on, I’m on, and if I know I’m not capable of being on, that’s why I would say that’s what I couldn’t film today,” said Lohan. “No one knows this. … I had a miscarriage for those two weeks that I took off.”

According to the 27-year-old actress, the miscarriage caused her to feel both physically and mentally ill. “I couldn’t move. I was sick. And mentally, that messes with you,” said Lohan, who called watching the entire experience over again surreal. “I cried so many times watching it because I don’t see it as me. It’s strange,” she said. “Watching this series, I just know how I felt at that moment and I can relate to that girl, which sounds kinda crazy, but I’m like, ‘Oh my God, this is really sad, like whose helping her?’”

Following her announcement, fans of the former Disney star are speculating about the identity of the father of Lohan’s alleged baby. While the actress has yet to confirm or deny anything, the “Mean Girls” star has been linked to four men during or prior to filming the series. So just who was Lindsay Lohan’s baby daddy? Here are the alleged candidates:

Michael Neeson

According to a report from Radar Online, Lohan was spotted spending time with “Taken" actor Liam Neeson’s 18-year-old son Michael while filming the series. Despite Lohan’s alleged nightclub fling with Neeson, Lohan denied dating the teen. “Lindsay Lohan is practicing the safest kind of sex — NONE — because she’s too busy focusing on her career to worry about boys,” reads a December 2013 report from TMZ, which claims that the actress laughed off the dating claims and was “only friends” with the A-lister's son. Michael Neeson is also the son of the late actress Natasha Richardson and grandson of actress Vanessa Redgrave and director Tony Richardson.

Vladimir Averyanov

Radar Online reported Monday that Lohan was also spotted with Russian model Vladimir Averyanov while filming "Lindsay."

Liam Dean

In October, Lohan was rumored to be dating New York model Liam Dean, 19. According to Radar Online, the actress and the fashion star dated for a few weeks. The actresses rep denied the rumors, calling reports of their relationship “completely false.”

Matt Nordgren

US Weekly reported in September that Lohan was seeing former NFL player and “Most Elligible: Dallas” Bravo reality star, Matt Nordgren, 30. According to reports, the duo started a romance after several years of friendship. “He’s a great influence on her,” a source told the magazine. “He’s also a Christian and won’t drink about her. He’s trying to keep her sober and on the straight and narrow. He’s really good for her.”

Despite their rumored blossoming romance, the pair reportedly called it quits just three weeks later with insider citing “work schedules” as the cause of the split.
