Kim Kardashian's brother Rob teased that he hoped her infamous sex tape "haunts [her] for the rest of [her] life" following an argument.

In the latest episode of Kourtney & Kim Take Miami, the two reality TV beauties are seen trying to help their younger brother deal with his split from singer Rita Ora.

After dishing out some advice to Rob, Kim is seen talking to camera about her brother's latest escapades, explaining: "Ever since Rob has broken up with his girlfriend he has been dating all these girls that I don’t think are his type."

Afterwards, things turn sour when Kim tells Rob that she won't set up a collaboration between her rapper beau Kanye and a friend of her brother's.

Detailing the conversation between herself and her brother to mom Kris Jenner, Kim revealed: "He said, 'I hope your sex tape haunts you for the rest of your life and I'm going to publicly bash you and Kanye.'"

After the spiteful argument, Rob is seen calling Kim to apologise while she's at dinner with Kanye, sister Kourtney and her son Mason - blaming his recent love split on the fact that he lashed out.

"I wanted to apologise. Obviously the things I said to you in the text message, I was just being mean," Rob said, before Kim replied: "I appreciate you being mature and calling me instead of dragging this fight out."

Kim later levelled with Rob about his romance woes. The beauty - who famously divorced her husband Kris Humphries after just 72 days of marriage - explained that she was eager to help Rob.

"When I was in my last relationship I clearly wasn’t happy. Khloé called me out on it all the time," she said. "I don’t want you to be taken advantage of by the lame girls out here."
