The Real Housewives of Orange County's Kelly Dodd is being exposed by former schoolmates for her lying and bullying ways that began long before she a reality television star. Apparently, it all started early on!

A blast from the past

A few students who attended St. Mary's High School in Phoenix, Arizona spoke with RadarOnline about the woman who was known to exaggerate her background and attack others she felt were beneath her. One of the sources described Dodd's behavior as "hateful and loud."

The source added that the RHOC star would often “try to pass herself off as a nice, Christian kid,” but was a "horrible person" in reality.

Kelly Dodd also spread rumors about the classmate and was said to be unapologetic when confronted about it. She also made everyone think she was from Scottsdale instead of Glendale. She was allegedly making herself out to be more than she was because money and status have always been a big deal to her. It's fitting that she's on The Real Housewives of Orange County.

Kelly got into a lot of fights in high school

Dodd had no qualms about getting into fights all the time. She never thought before speaking, according to another source who recalls their days in high school. The RHOC mean girl got into fights often.

On RHOC, Kelly is seen feuding among the other costars. On the latest episode, she said insulted Shannon Beador by telling her how ugly she thought she was and that she didn't blame her husband, David, for cheating on her.

As Radaronline continues in its report, Dodd's ex-fiance's wife filed a restraining order against her after feeling threatened by her. Dodd was allegedly sending alarming text messages and emails to Dana Caldwell and her son, Jake. The restraining order was filed in January 2014, but Jeffrey Caldwell requested that his ex stays at least 100 feet away from Dana and Jake.

According to the report, the case was dismissed in February 2014.

It's not hard to believe Kelly Dodd has this mean girl past given how good she is at showing this side of herself on The Real Housewives of Orange County.
