Khloe Kardashian has slammed Kourtney's toyboy ex - days after pretending she had forgotten his name.
In scenes aired in the latest episode of Keeping Up With The Kardashians, the siblings spoke to camera about 41-year-old Kourt's fling with 27-year-old toyboy Younes Bendjima.
On Thursday's episode, Khloe, 36, asked her eldest sister if she still hears from "what’s his name."
Kourtney replied: "No, never."
Her dislike for the Algerian model clearly rose to the surface as she probed: "Do you look back and think he might have been a bit negative for you?"
Kourtney said: "Yeah. He will text me once in a while."
Last night, she reiterated her opinion on the much-younger man with a scathing tweet.
She tweeted: "He was sooooooo toxic and negative for Kourt #KUWTK."
Kourtney met Younes in October 2017, and he was her first public relationship after splitting from long-term partner Scott Disick, with whom she has three children.
Khloe isn't the only member of the reality show's cast to have amplified a moment on the show on their personal social media channels this week.
Yesterday Kendall Jenner scolded mum Kris for posting a tweet that implied she was pregnant.
The momager was referencing the model taking on babysitting duties for her sisters and their pal Malika's 4-month-old son in the latest episode.
"You got this Kendall," Kris tweeted followed by a baby bottle emoji.
"Mom, this looks like a pregnancy announcement!" Kendall hit back.
This is the final series of KUWTK, and fans are eagerly awaiting scenes showing the breakdown of Kim's marriage to rapper Kanye West.
However, one member of the family who is loved-up at the moment is Kourtney.
She has started dating her longtime friend Travis Barker, who has been telling the world how good things are going for them by posting love notes sent to him by the usually dour reality star.
One read: "To lots of fun adventures, may we destroy each other completely."
