Miley Cyrus 'clinging to wedding plans'

Miley Cyrus is apparently too "brattish" to cancel her wedding to Liam Hemsworth.

Despite reports the former Hannah Montana star and her Hunger Games fiancé have split, it seems the singer is in no rush to call off their upcoming nuptials.

The 20-year-old is reportedly in denial their relationship has ended and Liam is said to be growing exasperated with her attitude towards the split.

"Liam is fed up of Miley's brattish behaviour. She always needs to be the centre of attention," a source sighed to British newspaper The Sun.

The blonde start underwent an extreme makeover last year, shaving off her long locks and posting pictures of her new look on her Twitter page.

Whereas fans complimented her, it seems the changes didn't go down well with her beau.

"Her freakish transformation has also turned him off. He thought getting engaged would calm her down but she is always looking to make another change," the insider explained.

Since reports of their breakup emerged, Liam has been spending time with family in his native Australia.

His different upbringing is said to have contributed to the split.

"His family thought they were too young to get married anyway. They are very normal and not showbiz at all," the source continued.

"He didn't grow up in the limelight like Miley did and he just couldn't get his head round it. The longer they were together, the more dramatic their relationship became."

Miley and Liam met on the set of The Song and the actor proposed in June last year.

Rumours their relationship had hit the rocks surfaced when Miley was spotted without her engagement ring and after Liam was linked to Mad Men star January Jones.
