Sisters Take Screaming Match to the Street in 'Bridezillas' (VIDEO)

Erica, a not-so-blushing bride to be, got into a nasty war of words with her little sister Jamika the night before her bachelorette party on 'Bridezillas' (Sun., 9PM ET on WE).

The screaming match, which later turned violent (shocker!) and spilled out onto the street for the entire neighborhood to witness, began when Jamika announced that she was too busy studying to help Erica with her party favors.

As anyone who watches 'Bridezillas' knows, you're not suppose to say "no" to the Bridezilla in your life, especially when she demands that you put down the books to help her do some serious party planning.

This Bridezilla breakdown -- one of many during this week's episode -- ended with Erica defiantly tossing Jamika's book bag in the garbage can. Jamika learned a hard lesson that night: Sometimes bedazzling party cups takes precedence over some silly book learning!
