Sunrise host David 'Koch' Kochie ranks the celebrities he's ...

He has interviewed countless high profile stars since joining Australia's most popular and highest-rated breakfast show, Sunrise, in 2002.

And on Wednesday, David 'Koch' Kochie did not hold back as he ruthlessly ranked several celebrities from one to ten following his experiences with them on the celebrated Channel Seven show.

Speaking with Kyle Sandilands and Jackie 'O'Henderon on their KIIS 106.5 radio show, the 64-year-old sang the praises of an iconic British actress before slamming one of the music industry's biggest stars as well as an acclaimed actor.

David, who hosts Sunrise, alongside Samantha Armytage, was first asked to rank Canadian superstar, Justin Bieber.

'He's a three! He was just a brat, well he was back then. [He was] Just a bit of a diva. One of our floor managers was positioning him for a song and gently said, "this is where you stand", and he said, "don't you dare touch me!"

'But by the looks of it, he's sort of grown up and matured and is quite a good boy now'.

David then gushed about American pop star, Katy Perry, saying: 'She's bright, talented, quick-witted, and effervescent. She did the weather better than our weather guy does. I'd definitely rank her an eight or nine!'

Jackie responded: 'I have to agree with you on Katy Perry. In the whole time that we've known her, from the very beginning of her career to now, she's never changed and has always been an absolute darling.'

'He was a brat!' David gave Canadian superstar, Justin Bieber, a three. He explained that Justin furiously told their show's floor manager 'don't touch me' when he was 'gently positioning' him to perform his song years earlier. David noted that he appears to have 'matured' now

Next up, David was asked to rank his interview with American actor, Michael Richards, 71.

'He was annoying, and probably would have been a four!' David furiously expressed.

'I'm a huge Seinfeld fan, and I was really looked forward to interviewing him. Everyone wanted him to be funny, and so I fed him a line to be funny, and he was deadly serious!'

'So I was like he's being Michael Richards. So I fed a serious line to him, and he was funny! I went, "who are we interviewing here?" I'd give him a three'.

An exasperated Kyle noted: 'When you're doing an interview, you would expect everyone to be on their A-game because they are usually selling something - a show, a book, a movie.'

Jackie added: 'It's astounding how many don't give a sh**. Just don't bother then. I'd rather no interview than this'.

'Definitely an eight or nine!' David then gushed about American pop star, Katy Perry, saying: 'She's bright, talented, quick-witted, and effervescent. She did the weather better than our weather guy does'
