Liam Hemsworth has filed for divorce from Miley Cyrus, eleven days after it was revealed that the couple had separated.

The Australian actor filed a petition to end his marriage to the American pop star and actress in Los Angeles on Wednesday (August 21).

The request states that he is asking for a dissolution of their marriage, and that they do not have children.

According to US website TMZ, he cited "irreconcilable differences" as the reason for their split in the court documents.

The couple, who first met while filming 2010's The Last Song and dated on and off for years before tying the knot in December 2018, announced on August 10 that they were going their separate ways so they can "focus on themselves and careers.

"Liam and Miley have agreed to separate at this time," a representative for Cyrus told People in a statement.

"Ever-evolving, changing as partners and individuals, they have decided this is what's best while they both focus on themselves and careers.

"They still remain dedicated parents to all of their animals they share while lovingly taking this time apart. Please respect their process and privacy."

Hemsworth later posted on Instagram that he wished Cyrus "nothing but health and happiness going forward".
