'I shouldn’t be saying this but he was kind of a brat,' she said when asked about working with the Baby singer.

'He was very nice to me. But he locked one of the producers in a closet and he put his fist through a cake that was on the cast’s table.'

Helgenberger visibly rolled her eyes when asked if his role was written to raise ratings, or because the singer is 'truly a good actor.'

'Justin Bieber wasn’t bad bad,' Helgenberger said. 'But he’d never acted before... He’s better than you’d think.'

Helgenberger's critique was very different to the official line on Bieber.

‘He did a really good job,’ CSI's executive producer Carol Mendelsohn told USA Today earlier this year.

The character was a member of an anti-government family whose foster dad was in jail and whose brother was out for revenge against the police.

The second episode ended with Bieber's character being gunned down in a stand-off with police.

Bieber said at the time that he was excited about the role.

'It was really cool because I actually - I get shot, like several times,' he said.

'I fall down and there's fake blood and everything. It's crazy how the whole process is.'
