Up until the startling moment the bride abruptly turned evil, everything appeared to be OK.

Before the unexpected turn of events, the bride and groom clasped hands and grinned broadly as the lady carried a bouquet.
Within moments, she abruptly released the groom’s hand and gave him a slap on the back of the head.
After that, as the bridesmaids and groomsmen hurried to step in, she threw the bouquet to the side and collected her flowing gown in preparation for a battle.
Following her aggressive attempts to rip at her fiance’s garments, the best men and the rest of the bridal crew joined in to restrain her.
