Patrick Swayze's widow is revealing new details about the late actor's childhood in a new documentary marking a decade since his tragic death.
Lisa Niemi Swayze - who was married to the Dirty Dancing star from 1975 until his death in 2009 - claims her mother-in-law, Patsy Swayze, physically abused her husband during his youth.
'She could be very violent,' Lisa reveals in the documentary I Am Patrick Swayze, set to air on the Paramount Network on August 18.
Patrick was the second of five children born to Patsy and her husband Jesse, who raised their brood in Houston, Texas.
Patsy was a well-known choreographer and dance instructor, who ran the Swayze School of Dance, which trained several Emmy and Tony-Award winning stars.
Patrick soon began taking dance lessons from his mother at the studio, and Lisa says that Patsy's perfectionism and high-expectations often veered into physical abuse.

In an interview with People magazine to coincide with the documentary's premiere, Lisa claims Patrick told her that his mother hit him during his childhood.
She told the publication that Patrick often used to tell a story about the day the physical abuse finally ended.
According to People, 'Patrick privately recounted the story of his 18th birthday when Patsy was 'laying into him' before his father [Jesse] told his wife [Patsy] that he would divorce her if she touched their son again'.
'She never hit him after that,' Lisa told People.
Patsy herself had also endured a violent childhood, and Lisa labels the perpetuation of behavior 'an example of what happens in families in a cycle of abuse'.
Meanwhile, Lisa went on to meet Patrick the year he turned 18, following her enrollment as a student at the Swayze School of Dance.
She claimed that Patrick later began to view Patsy more positively once he moved out of home.
