One of Johnny Depp and Amber Heard's Biggest Fights Happened After She Accused Him of Cheating

"She questioned him about it and he blew up at her, got in her face yelling, chased her upstairs," a source tells E! News

Insight on what may have caused a huge blowout between Johnny Depp and Amber Heard has surfaced.

The couple's highly publicized divorce has brought to light a number of issues the couple were dealing with behind closed doors, including alleged abuse in their marriage. But now, E! News learns that one of their biggest altercations occurred after Heard had a feeling that Depp had been with someone else.

A source close to the situation tells E! News that Heard had suspicions the actor was unfaithful, and confronted him about it, which "was the cause of one of their biggest fights."

"Johnny had a night out and Amber had a feeling he had been with someone. She questioned him about it and he blew up at her, got in her face yelling, chased her upstairs. Amber was scared." The insider added that Depp "didn't admit to anything," but apologized to Heard for his reaction and "she ultimately forgave him."

Just last month, E! News confirmed that Amber and Johnny were calling it quits after being married for a little over a year. Since papers were filed, Amber has revealed several allegations against her estranged husband including specific instances of domestic violence, which were explained in the actress' restraining order deposition documents (no claims of cheating were noted in the court documents).

Depp's ex Vanessa Paradis has come to Johnny's defense, shooting down any idea that the celeb is abusive. Additionally, a source close to Paradis tells E! News, "Everybody in the French community in France that know Vanessa and Johnny have only ever said good things about him. Vanessa and Johnny didn't split because he was allegedly abusive to her, they are still best friends and still get along really well."

The insider continued, "They just stopped caring about each other romantically and it didn't work out. Vanessa never showed any indication that she was a victim of abuse—while she was with Johnny or after they split. Vanessa loves him still and her French friends do too, they know Amber is unpredictable and always felt she was just in it for the fame."  

While Johnny has yet to directly comment on any of the allegations, his team released a statement shortly after divorce papers were filed.

"Given the brevity of this marriage and the most recent and tragic loss of his mother, Johnny will not respond to any of the salacious false stories, gossip, misinformation and lies about his personal life," his rep told E! News. "Hopefully the dissolution of this short marriage will be resolved quickly."
