Another day, another terrifying update on actress Hayden Panettiere and her tumultuous relationship with Brian Hickerson.

Hickerson was arrested in May on Domestic Violence charges and is currently out on bond.

The incident was initially shrouded in secrecy, but we now know that Panettiere was Hickerson's victim, and cops responded to a call from a neighbor who claimed to have heard a woman cry out in pain.

Little is known about Hickerson, but court filings pertaining to his upcoming trial paint a picture of a very unstable and frightening man.

We already knew that Hickerson had been arrested for assaulting his father in the early months of his relationship with Hayden (who was on the scene and witnessed the alleged assault).

Now, we know that that wasn't the first time in the past year that Hickerson's violent temper has brought him into contact with police.

Far from it, in fact.

According to a new report from Radar Online, police were called to Hayden's home in August of 2018 when Hickerson allegedly assaulted his brother.

Then, in October of the same year, police responded to a "group disturbance" at Panettiere's residence.

The exact nature of that incident remains a mystery.

Cops were back at Hayden's palatial Hollywood Hills home just a few weeks later when neighbors reported a “verbal dispute” between a male and female who sounded as though they were “possibly breaking items.”

A judge has issued an order of protection prohibiting Hickerson from coming within 100 feet of Panettiere.

Clearly, he's not too concerned with the consequences of violating the order, however, as Brian and Hayden are still dating despite the numerous violent incidents that have marred their relationship.

According to Radar, Hickerson was in court today for a preliminary hearing, and he had a surprise guest with him.

The 30-year-old has apparently hired top-dollar defense attorney Shawn Holley, who has previously represented the likes of O.J. Simpson, Kim Kardashian, and Lindsay Lohan.

Little is known about Hickerson's finances, but it seems likely that Hayden will be footing the bill for Holley's services.

Concerned family and friends have pleaded with Hayden to end her relationship with Hickerson.

We can only hope his trial -- set to begin August 28 -- will serve as an eye-opener and inspire her to flee.
