Khloé Kardashian felt "violated" after her sister's boyfriend aggressively flirted with her.
The reality TV star has an up-and-down relationship with Scott Disick, who is the father of her sister Kourtney's two children. Although she and Scott haven't always got on, recently they have been on better terms.
In an episode of US TV show Kourtney & Kim Take Miami, Khloé and Scott spent some time together while Khloé's sisters house hunted. Scott took things a little too far, prompting Khloé - who is happily married to basketball star Lamar Odom - to discuss things with Kourtney.
"He kinda crossed a line with me," she explained. "It was so uncomfortable. I felt so violated."
She then added to Scott: "Lamar might assassinate you."
Things became too much for Khloé when she and Scott decided to get some ice-cream together. As she was munching her vanilla iced treat, some of it went on her lip and face. Scott bent over to clean it off, much to the 28-year-old's horror.
"Scott! Oh my God! Don't touch my lips, dude! You gotta stop!" she squealed.
Apparently not realising she was being serious, Scott continued to make suggestive remarks to his girlfriend's sibling.
"You're really workin' that cone, Khlo!" he giggled. "You're a very sexual eater. In all honesty, who wouldn't want to be that cone' Your milkshake brings all the boys to the yard, does it not'"
Later, the pair went to a nightspot with Khloé's brother Rob and Scott spent a great deal of the evening being overly flirtatious and touching Khloé.
Kourtney was uninterested when her sister moaned about Scott, much to Khloé's amazement.
"I don't know what's wrong with Kourtney," Khloé mused. "I've been basically telling her that Scott is sexually harassing me!"
Scott eventually took some time to think about the incident and admitted he had "pushed a line" and would think carefully about his behaviour in the future.
