KHLOE KARDASHIAN yells "liar!" at boyfriend Tristan Thomas after learning he's cheated on her with family friend Jordyn Woods.
The dramatic scenes, which will be played out in the new series of Keeping Up With The Kardashians, show Khloe sobbing that he has "no respect" for her.
Betrayed Khloe, 34, posted the trailer for the 16th series on her own Instagram on Wednesday.
The clip opens with the tearful new mum saying in a confessional: "It just sucks that it has to be so public. I'm not just a TV show. This is my life."
A montage also shows the moment the family host a dinner in celebration of Kylie and her best friend Jordyn's successful joint business venture, before the Kardash-Jenner clan learn of Tristan and Jordyn's alleged kiss at a party.
In gripping scenes, Khloe, 34, is seen sitting in her car screaming down the phone to someone: "My family is ruined!", no doubt in reaction to the news that her basketball player beau - who was caught cheating on Khloe days before she gave birth to their daughter True in April last year - had been unfaithful again.
She later reasons: "Tristan might love me, whatever that means, but he has no respect for me whatsoever", whilst in another heart-wrenching scene, she screams down the phone, "Liar!"
While her mum and manager, Kris Jenner, claims the family "just can't seem to catch a break", Khloe praises her 11-month-old daughter as her beacon of light, saying, "True is the best thing that happened to me."
The end of the trailer shows Khloe in another teary confessional as she makes a plea for people to be kinder.
"Sometimes the world forgets to be kind and we're all going through something," she says.
Other scenes show Kim and Kanye West announcing they're having a fourth baby, Kendall modelling at the Victoria's Secret Show and Scott Disick and Kourtney playing happy families, despite being with other partners.
Keeping Up With The Kardashians airs this Sunday on E!.
