Real Housewives of Orange County star Kelly Dodd is “over the moon happy” that her divorce from ex-husband Michael was finalized, but the feud between the exes is still nastier than ever.

Although the official reason for the Dodds' split was listed on court documents as “irreconcilable differences,” Breaking Celebrity News has exclusively learned that a possible infidelity led to the marriage's demise.

“Michael acts like he is so innocent but that is not the case at all,” a source close to the cast told Breaking Celebrity News. “The real reason they split was because Kelly believed Michael was having an affair throughout their entire marriage with a 25-year-old!”

As Breaking Celebrity News previously reported, the brunette beauty and mother of Jolie, 11, initially filed for divorce in 2012, but the pair reconciled. She announced her intentions to move ahead with the split in September.

Leading up to their split, cops were called to the estranged couple’s Newport Beach, Calif., eleven times in one year.

Breaking Celebrity News reached out to both Kelly and Michael, but neither party was available for comment.
