The former Hannah Montana star, 17, believes that her quest for superstardom caused Tish and Billy Ray’s impending divorce, according to Popeater.com.
A source told the entertainment website: '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.
'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. It's heartbreaking.”
The source added: 'You would think that 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.
“I'm sure when she blows out her birthday candles in a few weeks, her wish will be for mum and dad, not her career.'
