Los Angeles: Reality TV star Kim Kardashian says she was terrified of dancing beside singer Beyonce Knowles.

After a salsa class during the family's trip to Cuba on a new episode of "Keeping Up With the Kardashians", Kim revealed her fear, reports eonline.com.

"Like, it was our biggest fight that I don't dance at Kanye's concerts," she told Kourtney Kardashian and Malika Haqq. "I did not dance on 'Dancing With the Stars'. Like, I did not dance!"

It also didn't help Kim's case that during Kanye West's 2011 joint tour with rapper Jay Z, she had some major competition in Beyoncé.

Kim explained: "My biggest fear was during Watch the Throne that if I sit next to Beyoncé, she dances and she's up, like, you know. So, the last night of the tour, she came to dressing room and was like, 'Hey, do you want to sit together?'"

Kim then pretended to cry while she recalled the experience.

"Then, she wanted to go in the mosh pit and I was like, 'What do we do in the mosh pit?' She's like, 'Dance! Just let loose. Just dance!' And I was like, 'My life is over!'"
