If you haven't seen this epic cat-fight video that went viral recently, you gotta watch it here and now.

A wedding in Shenzhen, China, was crashed by the groom's pregnant mistress, who turned up at the wedding in a wedding gown of her own.

The footage shows the bride and mistress screaming at each other in between physical fighting while some of the guests attempt to break them up.

At some point, the bride is quoted to have shouted at the mistress, "'You didn't have an abortion while you could and now you come here with your big stomach."

Witness the insane fight in the video below:
