The 30-year-old recently revealed she still loves her estranged husband, and wants him to make things right between them.
But Lamar, 35, has allegedly ignored Khloe’s public plea and instead got together with former girlfriend Lara Manoukian.
A source told Hollywood Life: “Hearing that Lamar is back with his ex is crushing for Khloe.
“She’s heartbroken over it and still doesn’t know if she believes it. To find out another woman is making him happy is like a knife to the heart.”
According to the Kardashian insider Lamar, who split from Khloe after allegations of his drug use, is doing well with Lara.
The source continued: “Hearing that he’s also doing better than ever living a good clean life while with this woman is even harder to deal with.”
It comes after Khloe told E! News that if she had it her way, she and Lamar would still be together.
During a recent trip to her father’s home country of Armenia, Khloe purchased a plot of land for siblings Rob, 29, and 35-year-old Kourtney, and the document showed she is still using Lamar’s name.
And recent US reports suggested that Lamar and Khloe’s divorce case could be thrown out of court because she is hesitating in filing the necessary paper work.
It seems Khloe wants nothing more than to get her happily ever after with Lamar, so we hope for her sake his relationship with Lara is just a rumour.
