Liam Hemsworth is officially done with his married life to Miley Cyrus, filing divorce papers in Los Angeles.

The Australian, 29, has hired famed divorce lawyer Laura Wasser, and filed the papers, citing "irreconcilable differences".

The pair announced on August 10 that they had split after seven months of marriage, reports news.com.au.

The next day, Cyrus was spotted kissing long-time friend Kaitlynn Carter, who had recently announced she had split from reality TV star Brody Jenner, who is the half brother of Kendall and Kylie Jenner.

However, some had initially hoped that the separation may not lead to divorce.

That was until Cyrus released her song Slide Away last week in which she sings

"Move on, we're not 17/ I'm not who I used to be/ You say that everything changed/ You're right, we're grown now"

Hemsworth and Cyrus first met in June 2009 when they were making the movie The Last Song.

They became engaged in June 2012 but then in September 2013 they had split.

In January 2016 Cyrus confirmed that she is back together with Hemsworth and that their engagement is back on.

In December 2018 the couple were married at their home in Tennessee.

The divorce papers do not state the date of separation with the paperwork simply saying "TBD" or To Be Decided.

The couple had a prenup and there is no request for spousal support so the divorce should be finalised quickly.

Sources close to Cyrus had told TMZ that she tried "valiantly" to save the marriage but couldn't accept Liam "drinking a lot" and "using certain drugs".

However, sources close to Hemsworth told the site that those comments were an attempt to distract from her infidelity.

The only thing Hemsworth has said is via an Instagram post.

"Just a quick note to say that Miley and I have recently separated and I wish her nothing but health and happiness going forward," he said.

Cyrus has been seen around Los Angeles with Carter reportedly making out at the Soho House and driving around together.
