Actress Amber Heard has filed for divorce from Johnny Depp after 15 months of marriage, citing irreconcilable differences.

Heard's filing on Monday followed the May 20 death of Depps mother, according to TMZ . People magazine confirmed the divorce petition.

Depp, 52, met Heard, 30, on the set of the 2011 film, "The Rum Diary." They married in February 2015.

The divorce filing follows months of speculation about a spilt. Heard acknowledged the challenges of her marriage to Marie Claire in December.

"I try not to react to the horrible misrepresentation of our lives, but it is strange, and hard, she said.

Representatives for the couple did not immediately reply to requests for comment.

Last month, Depp and Heard appeared in an awkward video publicly apologizing for bringing dogs into Australia illegally.

This would be Depps second divorce. A marriage to Lori Anne Allison ended in 1985.

Prior to meeting Heard, Depp had a 14-year relationship with actress Vanessa Paradis. They have two children together. Depp also had a relationship with model Kate Moss for several years.

The divorce filing comes just days before the release of Depps latest film, "Alice Through the Looking Glass," in which he plays the Mad Hatter.
