A groom's "side chick" showed up at his wedding in a WEDDING DRESS and demanded that she be the one to walk down the aisle with him, not his finance.

This happened in South Africa and you can see the mistress attempting to talk to the bride, but the bride-to-be is totally ignoring the situation. How did she not lose it here?

A bridesmaid is seen in the video attempting to remove the mistress from the church. I don't know what the end result was here, but I can't imagine this wedding happening after this.

Imagine you being the one about to walk down the aisle and this happening to you!!!

Ouch.
