Fallen star Lindsay Lohan revealed Sunday night that she had suffered a miscarriage.

She dropped the bombshell near the end of what was probably the final episode of her reality show on Oprah Winfrey’s OWN network.

The show, which follows 27-year-old Lohan through her day, ran a recent clip of her arriving hours late to film a segment of Fuse TV’s “Billy on the Street.”

At first, she blamed a severe chest cold. But then she broke into tears and said she’d been late for public appearances — and had to take time off — because of her secret pregnancy.

“No one knows this, but I had a miscarriage for those two weeks I took off,” she said, without naming the father. “I was sick, and that mentally messes with you.”

Several reports have said her show will not be renewed.
