Socialite Kim Kardashian says her baby daughter North became the victim of a racial attack while on a plane last month.

The reality TV star's one-year-old daughter, who she has with husband Kanye West, was allegedly screamed at by a woman while travelling in the business class, reports femalefirst.co.uk.

Speaking to her sister Khloe in the preview of a new episode of "Keeping Up with the Kardashians", Kim recalled the incident: "I fell asleep, I woke up to this woman screaming, 'Kanye West's baby!' The woman is screaming at my child, I jump up," before Khloe adds, "I would've punched her in her face."

Kim replied: "No, we were on a plane -- I wanted to."

Kim's mother Kris Jenner then told Khloe more details about the verbal attack later on in the episode.

She revealed: "This lady stood up in the cabin in first class and yelled at the top of her lungs, 'She's with a black guy, and that baby is black! And you need to shut that black baby up!'"
