Jesse James's sister has stated his recent claims that he was physically and emotionally abused by their father are "completely true."

"I saw it," Julie James England told E! News in a Wednesday interview. "I lived there with my dad, and he was very aggressive with Jesse and I. He did abuse Jesse."

The former Monster Garage and Jesse James is a Dead Man star made the abuse allegations during a Tuesday appearance on Nightline and said they were the main reason he entered Arizona's Sierra Tucson Treatment Center after infidelity allegations against him surfaced.

During the Nightline appearance, James recalled a specific incident when he was 7-years-old and his father chased him in the dark -- causing him to fall and break his arm before standing above him, laughing and calling him a "dummy."

However James' father Larry James has denied the allegations, instead claiming his son broke his arm when he fell off a fence after climbing it to retrieve a ball from a neighbor's yard.

"Just to show off... he dove over the fence, landed on the ground, and broke his arm," Larry told RadarOnline in a Wednesday interview.

"But I didn't break his arm. He did it by throwing a tantrum."

In addition, Larry's ex-wife Janina has also denied Jesse's abuse allegations.

"I think they are giving their stories to make money. Janina was married to my dad when we were teenagers. She doesn't know how angry my dad used to get with us. I don't know why she would speak out," England told E! News.

"My [birth] mom had to be my mother and my father. She would back us up. She would do anything for her kids."

England added that her brother has changed since leaving Sierra Tucson earlier this month.

"He is breaking the mold from what he learned from my dad," she told E! News. "He is owning up to the mistakes he made and is trying to move forward with his life. That's the best thing he could do for his kids."

While Larry has been estranged from his son since the reality star was a teenager, he said he'd like to reconcile at some point.

"I am so sorry for what has happened in his life. God knows I've made a lot of mistakes, unfortunately most of them has been with women," Larry told RadarOnline.

"I kind of know where he is at right now. I am always there for him... with open arms."
