Reality TV personality Kourtney Kardashian has branded her sister and star Kim Kardashian a "witch" and "narcissist " in a fierce row.

The 44-year-old reality star was seen arguing with her sister, 42, over the phone as the tense exchange was sparked by a conversation about the latter's collaboration with Dolce and Gabbana, which came just six months after the fashion house designed Kourtney's wedding dress, reports femalefirst.co.uk.
