Guy Sebastian, a coach on The Voice Australia, has been accused of being a 'total diva' on set, with reports suggesting his temper has become increasingly thin after six seasons. Insiders claim that crew members noticed he was more demanding this year, leading to speculation that the novelty of his role may be wearing off. Despite these allegations, Channel Seven has publicly dismissed the claims as 'complete rubbish,' asserting that Sebastian is well-respected and known for his hard-working nature. The show has historically experienced high turnover among coaches, which insiders attribute to long filming days and the challenges of maintaining enthusiasm over time. Additionally, the production's budget cuts since moving to Channel Seven may have contributed to Sebastian's frustrations, as he recalls the more extravagant treatment from the previous network. Overall, while rumors swirl about his behavior, definitive statements from Sebastian or his team have yet to emerge.
