Tori Spelling's husband Dean McDermott has been accused of flirting with one of the mom's at his son's school, Radar Online reports. A source told the site that McDermott reportedly took an interest in the woman and would "openly hit on her."

"Dean began brazenly hitting on a hot mom in their son Liam's class," a source told Radar. "She is a busty blonde, and always impeccably dressed, even for pick-up and drop-off."

The source said this all took place before the cheating scandal broke but Spelling recently found out about it from the other moms.

"The mom also has a son in Liam's class, and the two boys have had play dates together," the source added. "He would just say really inappropriate things to her, and complained Tori wasn't giving him sex. It got very awkward, as she never reciprocated any of Dean's overtures."

According to Radar, the actress cut ties with the woman and stopped her son from having any more play dates with the little boy. The Daily Mail reports that Spelling is even considering sending her son to another school.

The former "90210" actress and McDermott are currently documenting their marriage problems on a Lifetime docu-series called "True Tori." The show follows the couple as they attend marriage therapy sessions and try to save their rocky relationship. In one episode, McDermott admitted that he cheated and blamed it on a sex addiction.

He also complained that his wife was not having sex with him enough.

"We have four kids, so in the sex department there were ebbs and flows. Is that safe to say?" he asked, looking at the actress.

Spelling responded saying, "we had a great relationship and we had a great sex life."

However, McDermott told the therapist that they would only have sex "once every week."

"It wasn't fantastic," he added.

Spelling looked defeated while the therapist told the actor that his expectations of what a marriage was supposed to be like sexually, was "like a fairytale."
