Heard, 30, filed a divorce petition on Monday citing irreconcilable differences. The actress is asking for spousal support from Depp, 52, according to the documents obtained by PEOPLE.
The couple married in February last year after first meeting on the set of 2011’s The Rum Diary.
Reps for the couple were not immediately available for comment.
In December last year, Heard addressed split rumors to Marie Claire saying: “I try not to react to the horrible misrepresentation of our lives, but it is strange, and hard.”
The pair went public with their relationship the following year after Depp announced his split from partner of 14 years Vanessa Paradis.
On Wednesday, news also emerged that Depp s mother, Betty Sue Palmer, has died, ET reports.
