The 30-year-old actress filed for divorce from Depp, 52, this week, just days after his mother Betty Sue passed away and sources close to the pair claim that there was a "full-blown feud between his family and Amber," reported TMZ.
A source said that "Johnny's two children, two sisters and his mom hated Amber" and believed that she "treated [Johnny] like crap".
This will not be Depp's first divorce. He married make-up artist Lori Anne Allison in 1983 but they went their separate ways two years later.
Heard was in a three-year relationship with girlfriend Tasya van Ree until 2011.
