shannon beador's weight gain is not the fault of vicki gunvalson - at least that's what the "Real Housewives of Orange County" star has reportedly claimed. According to a new report, Gunvalson isn't willing to be blamed for Beador's stress eating and feels the only one responsible for Beador's size is Beador herself.

Earlier this month, Beador, Gunvalson and their co-stars were seen in the trailer clip for the upcoming 12th season of "The Real Housewives of Orange County" and, in the sneak peek, Beador was blaming Gunvalson for causing her to eat due to the stress of the drama between them.

Beador also admitted that eating was all she wanted to do.

Weeks later, a source has spoken to Radar Online and insisted that Gunvalson isn't at fault. According to the insider, Gunvalson is reportedly telling her friends that the fact that Shannon Beador is blaming her for her weight gain is completely ridiculous. Instead, she reportedly claimed, Gunvalson has informed Beador that the only reason she is "fat" is because she overeats.

As fans may recall from last season's storylines, Gunvalson and Beador had a major falling out when Gunvalson claimed that Beador's husband, David Beador, had been abusive towards her. Although the couple denied the allegations, Beador put an abrupt end to her friendship with Gunvalson, which had already been strained due to her former boyfriend's claims of cancer.
