They announced their separation over a week ago.

Liam Hemsworth has filed for divorce from Miley Cyrus citing 'irreconcilable differences.' According to TMZ, the actor filed a petition to end his marriage to Cyrus in Los Angeles today. Documents obtained by the publication showed that Hemsworth has asked for a dissolution of their marriage. The pair are believed to have had a prenuptial agreement before exchanging vows. Cyrus announced her split from Hemsworth last weekend, saying that the pair had decided to focus on themselves and their careers. https://www.instagram.com/p/Br3kgPKn0yN/?utm_source=ig_embed “Liam and Miley have agreed to separate at this time,” her rep told PEOPLE. “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.” The statement came after Cyrus was seen kissing Kaitlynn Carter while on holiday in Lake Como. Carter and husband Brody Jenner had announced the end of their own marriage just one week before. Cyrus and Hemsworth had an on-again-off-again relationship since 2009 when they met on the set of The Last Song. They married in December of last year. Hemsworth issued a statement via Instagram following their split saying that he would not be speaking to the press about the breakup. "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 wrote. "This is a private matter and I have not made, nor will I be making, any comments to any journalists or media outlets. Any reported quotes attributed to me are false." Cyrus has yet to comment directly on the split. She has, however, released a new song called 'Slide Away.'
