"Kourtney and Kim Take New York" debuts in a little over a week and will include footage of Kim Kardashian and Kris Humphries' marriage breaking down.
The show is an offshoot of "Keeping Up With the Kardashians" and finished filming its second season last month.
A source told Radar that Kardashian was not happy with the way Humphries treated her when she re-watched the footage.
"It was hard for Kim to watch all the footage, she has been unable to review it without bursting into tears...she was absolutely mortified when she saw on camera, the way that Kris was treating her," said a source to Radar.
The source also said Humphries mistreated the whole Kardashian family.
"The marriage was already under a tremendous amount of stress, but she just couldn't believe that she had married this man that was treating her and her family like this,” the source said.
Kardashian and Humphries married in August during one of the biggest celebrity events of the year.
The ceremony had 450 guests, including singer Ciara, tennis star Serena Williams and actress Lindsay Lohan. Kardashian’s sisters Kourtney and Khloe were bridesmaids at the event, which Khloe called "perfect."
Kardashian filed for divorce from Humphries on Oct. 31, citing irreconcilable differences, after just 72 days of marriage.
Since the news of the divorce broke, some have speculated the marriage and multimillion dollar wedding was a publicity stunt.
Celebrity lawyer Laura Wasser handled Kardashian's divorce as well as her prenuptial agreement and said Tuesday she does not think it is possible the marriage was fake
"Our office did indeed negotiate and prepare a prenup for Ms. Kardashian. Given what I know regarding that document, it is not plausible that this marriage was a sham," said Wasser to TMZ
A source close to Kardashian told TMZ: "Why on earth would they [Kim, Kris and their lawyers] create a document which looks far into the future if they planned a marriage that would only last a few months?"
Kardashian and her family also insist the wedding and marriage was real.
The second season of "Kourtney and Kim Take New York" debuts Nov. 27 on E! News channel.
