'RHONY' SPOILERS: Season 7 Cast Turns on Heather Thomson Following Sonja Morgan Drama

Heather Thomson better make nice with her fellow Real Housewives of New York City cast members, or she might find herself out of a job. The star, who boarded the series during season five, has allegedly been rubbing some of her co-stars the wrong way. While the star has mostly been butting heads with Bethenny Frankel during season seven, it looks like some of her other "friends" are giving her the cold shoulder.

According to Radar Online, the chilly exchange happened at the NBC Upfronts, which took place in New York City last week, and it appears that none of her RHONY ladies wanted to have anything to do with her.

"None of her costars were speaking to her," an insider explained to the news site, adding, "They're all fed up!"

It seems that Thomson was even excluded from the group pictures at the event, because no one wanted to be around her.

While Heather has always been one of the most level-headed housewives it seems that it is her storyline revolving around Sonja Morgan that is making the girls annoyed.

"Heather doesn't have a storyline, so she's attacking Sonja," the insider told the site. "She says Sonja has no brands and no business..."

While we find it hard to believe that Heather is using this as a storyline, fans did see her get into a heated argument with the veteran housewife during last week's episode in Atlantic City.

However, despite the reports, The Inquistr explained that Heather addressed her issues with Sonja in her Bravo Blog last week saying that she's "always tried to be on Team Sonja."
