Kardashian sisters slam Kourtney's boyfriend who defends himself amid sensational split

Despite their on-going sibling feud, Kim Kardashian defended her older sister on social media when the latter's ex-boyfriend spoke about their split.

Kourtney had been dating the 25-year-old former boxer and model, Younes Bendjima, but announced their split after recent photos of his trip to Mexico with his friends emerged.

In the snaps, Bendjima can be seen hugging and flirting Jordan Ozuna. TMZ reported that Kourtney broke off the relationship shortly before the trip.

Kourtney and Bendjima joined her mother on vacation in Positano, Italy less than a month ago for Kourtney's daughter's 6th birthday.

A month before that, the duo traveled to Arizona and spent long lazy days on a boat on Lake Powell. They stayed at the Amangiri Resort for the duration of their stay.

Once the news of their breakup made headlines, Bendjima shared a screenshot of an article to his Instagram Stories.

Superimposed text on the screen read: "They really want me to be the bad guy." He added:

"Can't have fun with your friends no more. [Daily Mail] where are my 12 others [sic] friendssss? [sic]"

Kim couldn't let the opportunity pass by and commented: "Nice pics from your 'boys trip.'" She added the Pinnochio emoji for good measure.

Khloe jumped to Kourtney's defense as well and wrote: "Alexa play 'heard it all before' by Sunshine Anderson.

Sisters Kourtney and Kim had a spat over December when the latter tried to organize a photoshoot and Kourtney didn't want to budge on her schedule.

Kim said that her eldest sister is "the least exciting to look at." Read more about it in "Here's the photo that sparked an epic family feud between Kim Kardashian and sister Kourtney."
