New court documents include Heard’s claims to a therapist that her ‘Aquaman’ costar arrived “drunk” and “late on set,” which DC Studios denies

New allegations from the Amber Heard and Johnny Depp defamation case are coming to light about Jason Momoa’s alleged behavior on the set of Aquaman.

According to court documents released last month and obtained by Variety, Heard, 37, described her costar as “drunk” and “late on set” in notes taken by clinical and forensic psychologist Dr. Dawn Hughes, who was brought on by Heard’s legal team to testify.

Hughes’ notes further state that Heard claimed Momoa, 44, arriving on the set of the DC Studios superhero film “dressing like” her ex Depp, wearing “all the rings.”

In a statement to PEOPLE, DC Studios said, “Jason Momoa conducted himself in a professional manner at all times on the set of Aquaman and the Lost Kingdom. We’re excited for audiences to see the film this December.”

Last year’s defamation trial in Virginia began when Depp, 60, sued his ex-wife for defamation over a 2018 op-ed she wrote that included abuse allegations. After the Pirates of the Caribbean actor won three claims and Heard won one of her three counterclaims, she paid him a $1 million settlement.

During their lengthy legal back-and-forth, Heard testified that her role as Mera in the upcoming Aquaman and the Lost Kingdom had become “very pared down” amid the public attention on her personal life. The franchise’s director James Wan said last month that her character was never intended to be a major part of the sequel.

“I fought really hard to stay in the movie,” Heard testified. “They didn’t want to include me in the film.”

"I was given a script and then given new versions of the script that had taken away scenes,” she added. “They basically took a bunch out of my role. They just removed a bunch out.”

Walter Hamada, then-president of DC Films at Warner Bros., testified in court that there were discussions among producers about a “lack of chemistry” between Heard and Momoa, and that her defamation trial had no impact on the size of her role in the franchise’s second installment. “The character’s involvement in the story was what it was from the beginning,” he said of Mera.

Heard’s talent agent Jessica Kovacevic then testified that she believed the attention the actress received during her televised trial opposite Depp had negatively impacted her career.
