AceShowbiz - Laura Prepon and her estranged husband Ben Foster are deep in a legal battleground amid their ongoing divorce. Both celebrities have traded severe accusations that have added fuel to the fire enveloping their separation process.

Their conflict recently intensified when Foster, 44, accused Prepon, 45, of "inappropriate marital conduct" in an amended divorce petition.

This claim was added to his original filing that cited "irreconcilable differences" as the reason behind their split. Foster's accusations included claims of "cruel and inhuman treatment," which rendered their cohabitation "unsafe and improper."

In a swift rejoinder, Prepon dismissed the allegations and demanded "strict proof" from Foster to substantiate his claims. In her response, she went further by accusing Foster of "habitual drunkenness," echoing her complaints made earlier when she cited his "longstanding history of alcohol abuse."

The couple's separation date, officially listed as September 9, 2024, marks the end of a relationship that began publicly in July 2016 and led to their marriage in 2018.

They are now engaged in custody battles concerning their two children: a daughter named Ella, seven, and a five-year-old son whose name has not been publicly disclosed.

Foster asks the court to enforce the pair's prenup and demands joint custody, contending that both he and Prepon are "fit and proper" parents. However, Prepon challenges this, pushing to be the primary residential parent and claiming it would be in the children's best interests.

An existing temporary custody agreement restricts the couple's alcohol consumption around their children, emphasizing neither should drink to the point of intoxication during their parenting time. This agreement also includes terms for out-of-state travel and prohibiting derogatory remarks about the other parent in front of the children.
