Terry McMillan says her storybook romance with a handsome 20-year-old bisexual Jamaican, who later became her husband, never happened the way she wrote it.
McMillan married Plummer in 1998 after meeting him while on vacation in Jamaica in 1995. Their marriage inspired her famous novel How Stella Got Her Groove Back.
Then rumors began to swirl that Plummer was a "down low" male seeing other men behind her back.
The couple divorced in 2005 after Plummer confessed that he was a homosexual.
In 2017, McMillan sued Plummer for $40 million, claiming he ruined her reputation as an acclaimed author by deceiving her into marrying him.
In a confrontation with Plummer on "Oprah" in 2005 -- McMillan claimed their marriage was "based on deceit" and she accused him of marrying her for money and U.S. citizenship.
Now that same-sex marriage is legalized, McMillan claims her famous novel was all a lie.
On Monday, she tweeted: "Personally, I was never waiting to exhale nor have I ever lost my groove. I write fiction. I lie such that it feels like the truth."
McMillan's Twitter followers were mostly supportive.
One user wrote: "Wish I could write my truth with half the authenticity and brilliance of your lies."
