Their friendship has stood the test of time, but now Khloe Kardashian wants an apology from Malika Haqq for having sex with her brother.

In the latest episode of her podcast Khloe in Wonderland, she had a few choice words for her best pal, who enjoyed a fling with Rob Kardashian, which fans watched play out on early episodes of reality TV show Keeping Up With The Kardashians.

Malika offered up an explanation when grilled by Khloe during their comedy chat. She said, "It started off as a joke," adding, “It started off as a joke to see if it would like, ruffle your feathers."

Khloe prodded further, she wanted answers. The mom-of-two did not mince her words when she said, "You went behind my back and were f------ my brother!" Malika stood her ground and insisted she did not do anything wrong. She said, "Was I supposed to say, ‘Hey Khloe?’, just, an announcement?" Khloe joked, "I should have known that you were having intercourse with my family member!”

The duo continued, with Malika adding, "Do I owe you an apology?" to which Khloe brutally replied, "You don’t owe me an apology, but what I am saying is that if I were to sit on your brother’s d--- I would be calling you right afterwards!"
