Celebrity Big Brother housemate Dane Bowers may come across as mild mannered on the Channel 4 reality TV show, however his former teacher claims that the opposite is true.

Dane attended a private school costing his parents £12,000 a year, however his constant outbursts and temper tantrums led to his exclusion at the age of 15.

A former teacher at Trinity School in Croydon, South London, told The Sun: “Dane may well come across as placid on TV, but he was a nightmare at school.

“It’s almost unheard of for someone to get kicked out of Trinity – it has to be authorised by the school’s governors.

“But Dane was just out of control and very difficult to teach. It just got to the point where he had to go.”
