Having waited nine years to walk down the aisle with her true love, Cristal Cavallaro thought she would have a dream wedding, but instead it was an utter nightmare, and she transformed into a fire-breathing dragon lambasting her fiance, falling out with her mother-in-law and driving her bridesmaid to tears.

"I thought I wasn’t going to be a bridezilla but looking back at all the stress that was going on, I guess I turned into one!" the newlywed from Anaheim, California told Breaking Celebrity News in an exclusive interview.

"I always think of myself as the nicest person in the world, and then the week of the wedding I started snapping and it was horrible."

The bawling and bloodshed of Cristal, 29, and Corey's 1920s themed wedding last June was caught on camera by WE TV's Bridezillas, and Breaking Celebrity News got an inside look at the diva's dark side before the grand finale airs on Sunday.

"The worst thing I did was go off on my mother-in-law to be. I said she was a b*tch and had no right to tell me that she wished her son wouldn't marry me." she told Breaking Celebrity News.

The drama started in the weeks running up to the couple saying their vows, when their families started snipping at each other at the shower. "Then the day of the wedding came and my in-laws went off on my husband, yelling and screaming saying they weren’t coming to the wedding," she explained. "It was a bad time with her. I don’t really talk to her even now although she lives two houses down from me!"
