A New Zealand TV reporter who took pop star Pink to task for allegedly sacking her sister has sensationally quit her job as bosses investigate the incident.

Tvnz's Hannah Hodson reportedly antagonised the So What hitmaker her during a TV interview in Sydney, Australia in October.

Hodson was allegedly angry with Pink for sacking the reporter's sister, who worked as the star's former assistant.

The interview became so tense, Pink stormed out of the scheduled chat as her manager attempted to confiscate the recording from the Tvnz crew.

According to reports, the interview was due to appear on New Zealand current affairs show Close Up but sources claim it was a "train wreck" that will never be aired.

Pink later labelled Hodson "insane", insisting she had tried to be polite throughout the promotional interview but claimed "it was really hard to stay".

And although Hodson's employers denied there was an argument between the journalist and Pink, Hodson resigned from her job as the incident was pending investigation, according to Australian reports.

It wasn't the first time Hodson had upset an interviewee - she stunned Nicole Kidman last year by reading out a scathing review of her film The Golden Compass during a chat with the actress.
