Twelve camels have been disqualified from a beauty contest in Saudi Arabia after their owners tried to boost their pouts with Botox.

The King Abdulaziz Camel Festival has been hit by scandal after some owners cheated in a bid to win the huge cash prizes.

A total of $57 million (45.8 million) is up for grabs at the annual event.

Thousands of camels are paraded at the festival to be judged on their physiques, humps, mouths and ears.

But this year, a dozen prized animals were banned after a vet was caught giving them Botox injections.

A UAE national paper reported that they had Botox injected into their upper lips, lower lips, noses and even jaws. They also went under the knife to reduce the size of their ears.

The month-long festival also features camel racing and camel milk tasting.
