Fantasia's Baby Deddy Now Says She Knew He Was Married...

Fantasia Barrino has long maintained that her baby daddy Antwaun Cook had split from his wife by the time they started dating, but new court documents obtained exclusively by RadarOnline.com prove otherwise.

Antwaun's estranged wife, Paula Cook, filed court documents in August 2010 claiming her husband began a "covert adulterous affair" with Fantasia in August 2009 — a claim which both Antwaun and Fantasia vehemently denied.

Photos first emerged of Fantasia and Antwaun getting hot and heavy in the Barbados in January, 2010, which is a full six months before he admitted the separation with his wife in court documents filed in North Carolina.

"The parties consent and agree that Palintiff [Paula] and Defendant [Antwaun] are husband and wife having been lawfully married to each other on October 1, 2005 and separated on June 16, 2010," the docs state.

By consenting to the date of separation being June 2010, Antwaun is admitting that he cheated on his wife with Fantasia.

During the earlier court proceedings, Fantasia, 28, was forced to admit private details about her relationship with Antwaun, including an abortion around the same time as her failed suicide attempt before they got pregnant again and had a baby boy last December.

Given Antwaun's admission of adultery, if his estranged wife desired to do so she would now legally sue Fantasia for Alienation of Affection, which is a North Carolina law in which one can sue the third party who "alienates" the affections of one spouse from the other spouse.

Just last year an unnamed jilted wife was awarded a $30 million "bench verdict" and the year before a $5.9 million case was awarded to the innocent spouse.
