Miley Cyrus has reacted after her estranged husband Liam Hemsworth filed for divorce. 

According to People, Miley Cyrus is 'disappointed' that he filed to dissolve their marriage.

The publication claimed the singer is upset with the 29-year-old actor's decision, as although she's 'doing well', it's 'hard' for her to accept her relationship is over.

A source told People magazine: 'She didn't expect it and is a bit disappointed, but she is still doing well and has obviously moved on as well.

'What she and Liam had for a long time was very special. It's just hard for her to think that she will never have this again with Liam. There are really so many things that she loves about him.'

In the divorce filing, Liam cited irreconcilable differences.

It was also revealed that they signed a prenup so their individual earnings during their marriage will remain separate and there is no request for spousal support.

A source told TMZ that Liam just wants to move on and is 'over the marriage.'

Liam is being represented by celebrity divorce lawyer Laura Wasser who did not state a date of separation on the petition, simply putting 'TBD'.

Miley Cyrus, 26, announced her separation from Liam Hemsworth, 29, on August 10, after only 8 months of marriage.

The shocking news came shortly after Miley was pictured kissing Kaitlynn Carter, who had also recently separated from husband Brody Jenner.
