Demi Lovato’s ex-fiance, actor Max Ehrich (pic), was arrested in South Florida after cops say he violently launched at his mum earlier this week.

The 34-year-old Young And The Restless alum was taken into custody Tuesday night in Port St. Lucie on a charge of battery on a person 65 or older, according to TMZ. Ehrich was released Wednesday after posting US$1,000 bond.

His mum reportedly told authorities that the violence began in the home that they share during an argument over a phone. She claimed Ehrich chased her outside onto a neighbouring property, threw her to the ground and kicked her in the thigh. He had allegedly been livestreaming the abuse, according to a call cops received reporting the incident.

Though Ehrich’s mum would not give a written statement or let police photograph her injuries, she reportedly said her son “heavily abuses inhalants,” among them nitrous oxide, which she claimed he had used ahead of Tuesday’s violence.

The actor has been placed on a psychiatric hold, under the state’s Mental Health Act or Baker Act, according to TMZ.

Ehrich and Lovato, 33, had a whirlwind romance in 2020, with the former proposing after just four months and their engagement lasting a bit over two.

An insider later told People that the Grammy nominee called it quits due to believing Ehrich was “trying to further his career” through their relationship.

The Disney Channel alum — who’s gearing up for the Oct 24 release of her ninth studio album, It’s Not That Deep — tied the knot with artist-songwriter Jordan “Jutes” Lutes earlier this year. – New York Daily News/Tribune News Service
