UFC star Amanda Nunes has shared a video of herself playfully bickering with her girlfriend Nina Ansaroff.

In the video Nunes says: "You have to apologise first."

Ansaroff says in response: "You apologise first, you started it, I acted on your anger. She was wrong and I'm not going to give her her sandwich until she apologises.

To which Nunes retorts: "She was wrong, she attacked me first."

Ansaroff replied to Nunes' tweet revealing the reason for the argument. She wrote: "She yelled at me for being out of milk. I don’t drink milk."

The pair have been together for years.
