'So we're going n****r hunting today or what?' a man can be heard asking in the video.

'We're f***ing n****r hunting right now,' he adds.

The camera then pans to Duncan who smiles as she says: 'You get them n*****s'.

'Look at my soon-to-be sister-in-law,' the man filming says seconds later. 'She looks so pretty.'

It is not clear where the racist video was filmed but Duncan lives in Jefferson County.

Duncan apologized after the footage went viral but insisted she was not racist.

'I was underage drinking and I said something stupid,' she told the New York Daily News.

'I have black friends, I have black people in my family, I didn't mean it. I didn't know that I was being (recorded).'

She had reportedly just enrolled in the US Air Force and was believed to be out celebrating.

Social Bar and Grill where Duncan worked as a waitress said they immediately fired her after they learned of the footage.

Management described the video as 'vile, disgusting and offensive'.

'The incendiary comments made by this employee absolutely does NOT represent the views, opinions, and policies of Social Bar & Grill and it's owners,' they said in a statement.

'Nor will they be tolerated in any fashion. Social Bar & Grill and it's owners continue to encourage and seek diversity in its restaurant.'

The Air Force says it is also investigating after people identified Duncan as a new enlistee.

'We have been made aware of a video online of an alleged reserve Airman who made racially insensitive comments. We are looking into the matter and we appreciate this being brought to our attention,' a spokesman said.
