Miley Cyrus would give up all her success and riches if it would keep her parents together

The 'Hannah Montana' actress and singer reportedly blames her popularity for parents Billy Ray, 49, and Tish, 43, filing for divorce after 17 years together, and would give everything up if it would mean they work things out.

A source close to the star told website Popeater.com: "It's heartbreaking. You would think someone like Miley has everything in the world, but I guarantee she would give it all up in a second if it kept her family together.

''m sure when she blows out her birthday candles in a few weeks her wish will be for mom and dad, not her career.

'Every marriage struggles when a child leaves home and the relationship gets re-examined, but add on top of that that every second of the past decade Billy Ray and Tish have spent building a star together, they have forgotten to make time for each other.'

Part of the reason former country singer Billy Ray ' who also appears in 'Hannah Montana' ' and Tish are splitting is said to be because Miley, 17 ' whose career is said to be worth over $50 million - has been so successful, and now she is old enough to look after herself, they don't have other things to work at together.

Another source added: 'Both parents have been equally involved in making their daughter a superstar.

'And now that they have achieved their goal they have nothing to work towards anymore and nothing to keep them together."

Billy Ray filed divorce on October 26, and asked people to pray for him and Tish to help them through the difficult and emotional time.

The pair are expected to file for joint custody of their three youngest children: Miley, 17, Noah, 10 and Braison, 16.

Billy Ray is also stepfather to Tish's two children from a previous relationship, Trace and Brandi.
