Ryan Phillippe's ex-girlfriend Elsie Rose Hewitt alleged that the actor physically abused her while they were still together, the Los Angeles Times reported on Tuesday. And now Phillippe has responded.

Hewitt filed a lawsuit Monday in the Los Angeles County Superior Court, claiming that Phillippe had hit, kicked, and pushed her down a flight of stairs on the fourth of July.

The alleged incident described in Hewitt's lawsuit was also reported to the LAPD.

According to Hewitt's lawsuit:

"[Ryan Phillippe] grabbed [her] upper arm so tightly that his grip left heavy bruises on her arm hours later. He then braced his body and threw her down his staircase as hard as he could."

The lawsuit alleges that after the couple had gone to a party together - Phillippe had left early without Hewitt - he became jealous of the attention Hewitt was getting from other men. Hewitt had left some clothing she needed at the actor's home, and upon arriving to retrieve her belongings, the lawsuit claims that an angry Phillippe threw her down the stairs and told her to leave his home.

Hewitt reported the incident to the LAPD that evening, and Phillippe was served with a restraining order two days later. (The restraining order is no longer active at this time.)

Hewitt's lawsuit also alleges that Phillippe had an intense drug addiction during the time they were together. According to suit, "cocaine, ecstasy, psychedelic mushrooms, and steroids" were just some of the drugs that the actor abused while they were in a relationship.

Phillippe spoke out and denied Hewitt's allegations in a letter he posted on Twitter Tuesday.

"I am saddened and disgusted by the false allegations circulated about me. At the time these allegations were initially made, I fully cooperated with law enforcement and a thorough investigation was conducted," Phillippe wrote. 

Phillippe continued to insinuate that Hewitt's allegations were made solely for "monetary gain."

Phillippe wrote:

"Domestic violence is a very real and tragic issue faced by many women the world over and should never be used to vengefully slander or as a ploy for monetary gain. This is wrong. This is not who I am. Every one of my accuser's allegations are false."

According to US Weekly, Hewitt is requesting $1 million from Phillippe in her suit.
