On a recent episode of "Keeping Up With The Kardashians," Kim Kardashian revealed that she and her baby North West were subjected to a racially motivated verbal attack during a flight from Vienna to Los Angeles.

The 33-year-old reality TV personality recalled that a woman who was also seated in first class started screaming racist remarks about her interracial relationships and her 1-year-old daughter.

"Mom had the baby, I fell asleep, I woke up to this woman screaming, 'Kanye West's baby!' The woman is screaming at my child, I jump up," Kim said to her sister Khloe on their reality show that aired on June 29.

"I would've punched her in her face," Khloe said.

"No, we were on a plane. I wanted to," Kim said. "It was crazy."

Kim continued telling her about the incident. "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!'"

Khloe said, "I would say, 'Hashtag, fact my baby is black. Hashtag, I only like black c*ck!' That's what I would say!"

Kim went on to say that the woman also brought up her notorious sex tape with her ex-boyfriend Ray J, shouting, "'And she has a sex video with a black guy. How disgusting, with a black guy.' Like going on and on."

According to Kim, the pilot eventually came out and threatened to have the woman arrested as soon as they landed. However, the woman's husband apparently sat on her and told her to "shut up," the Huffington Post reported.

"It was the trip from hell. It was so racist," Kim said.

Last month, Kim and her husband Kanye West celebrated their daughter's one year birthday will an over-the-top birthday party that included a Ferris wheel, teepees, celebrity guests and a makeshift Coachella stage.

In one photo that Kim shared on Instagram, North West is seen with her parents, her grandmother, Kris Jenner, and a rainbow-colored birthday cake. The baby appears to have just blown out the candle on her tie-dye cake, while her superstar parents are beaming with excitement.

"Our baby girl's 1st birthday party! #kidchella," Kim wrote as a caption.
