Jennifer Hudson Accuses David Otunga of 'Aggressive' Behavior & Claims He Taunted Her with Gun

In her request for a protective order, Jennifer Hudson accuses her ex-fiancé David Otunga of ongoing harassing and threatening behavior and claims he once pushed her inside their home.

“I am now living in fear of further action David might take,” the American Idol alum, 36, says in the order of protection, obtained by TMZ. Otunga has denied any claims of abuse or harassment via his lawyer, who told PEOPLE he plans to file for primary custody.

In a specific instance, Hudson claims Otunga, 37, called her repeatedly while she was at a recording session; when she didn’t pick up his calls, the star claims her ex then asked their 8-year-old son David Otunga Jr. to record the scene, reports the site.

Hudson also reportedly claims in the legal docs Otunga believes she is dating one of her producers, but she denies she is involved with anyone new.

After she arrived home that day, Hudson says Otunga was “visibly” angry and grabbed their son by the hand and pushed Hudson out of their master bedroom. The Oscar winner claims David Jr., a makeup artist and an assistant were all present during the incident.

The Voice coach also says the retired wrestler occasionally left a gun and holster — which he said was a movie prop — on their kitchen counter to intimidate her. “I believe that he left it out to taunt, intimidate and frighten me, which he absolutely accomplished,” she reportedly claims in the papers.

About a month after becoming engaged in Sept. 2008, Hudson’s mother, Darnell Donerson, and her brother Jason Hudson were found fatally shot in a Chicago home. Her 7-year-old nephew Julian King was found dead in the backseat of a car. Hudson’s former brother-in-law William Balfour was convicted of the murders in 2012.

PEOPLE confirmed exclusively Thursday night Otunga and Hudson have ended their relationship after 10 years together. “Jennifer’s actions are solely taken in the best interest of their son,” her rep said in a statement regarding Hudson’s request for a protective order, which gives Hudson possession of their residence and orders him to stay away from her and their son.

Otunga’s attorney Tracy M. Rizzo told PEOPLE in a statement her client “never abused or harassed Ms. Hudson or their son” and that he “looks forward to his day in court and in being awarded the residential care of the parties’ only child.”
