"She wouldn't even look me in the darn eyes!"

Former publicist revealed how Kate Gosselin is just an "awful human."

On her new reality show, 'Kate Plus Date,' Kate will be looking for a man this fall. But according to a former TLC publicist, she should be looking for something else instead.

Kate has been on celebrity gossips and on the lives of television show fans for years.

However, she's considered one of the most unpopular celebrities on the planet. She's seen by many as a loud, self-centered, and the worst narcissistic person you'll ever meet.

Known for berating her ex-husband, Jon Gosselin, on camera before and after their breakup and sending potential lovers running, an insider has revealed Kate treated the TLC publicist like dirt!

Former TLC rep Joey Skladany told Rob Shutter of 'Straight Shutter' podcast:

"Everyone warned me that she was difficult — and I said, 'No. I'll compliment her.'"

Skladany then shared a brief story that, according to his view, summarized why Kate really does suck.

He explained:

"At the Today show, I said, 'Your hair looks gorgeous!' She wouldn't even look me in the darn eyes!"

The mother of eight left a bad, lasting impression on the TLC publicist. Hilariously, Skladany said on the podcast:

"At the end of the day, I called my boss and said, 'She's an awful human.' They were like, 'We know. Thank you for the feedback.'"

Kate and Jon are still fighting over their children's custody, a decade after they got divorced. But Jon takes more responsibilities considering he takes care of his son Collin, who spent two years in a medical facility for 'anger' issues until his release last Christmas.

Jon also spends time with his daughter Hannah.

During a court hearing to determine who would live with Collin in early December last year, Kate didn't even show up.

And Jon was awarded temporary primary custody.

Jon and Kate's sextuplets just turned 15 years. Kate celebrated the day by sharing a post with a captioned photo with just Alexis, Aaden, Leah and Joel.

The caption read:

"Our big celebration of #15 is finally winding down here! We celebrated ALL DAY LONG, beginning with a present at 6:30 am before school! I'm so very thankful for my' babies…. some how they are 15 already?! I'm amazed by them each day."

"I'm so proud of the positive qualities I've seen developing as they edge closer to adulthood."

"It hasn't been easy for them, especially over the last year and a half, but they continue to persevere, stay positive and make lemonade out of lemons (to the point where I'm pretty sure I'm allergic to lemons, but what's a mom to do?) but no matter what, these kids keep on keeping on."

"Such good, wholesome, loving, insightful, wise humans and I'm just so proud to call them mine!"

"I love you guys to the moon and back a hundred billion times infinity. Happy 15th birthday!"
