Kylie Jenner is still nervous when she has to do a red carpet interview without her elder sister Kendall Jenner. In a new sneak-peek for Sunday, September 27's episode of "Keeping Up with the Kardashians", Kylie felt "sick" and was going to "faint" when she was about to do a solo red carpet interview at the 2015 Billboard Music Awards back in May.

Both Kylie and Kendall attended the awards event together. However, they had to part their ways as Kendall was promoting her H&M and Balmain campaigns. "It's kind of weird cause Kylie and I usually do carpets together but I'm actually with H&M and Balmain and I really on my work 'cause that's what I am here for," Kendall said.

Because of her contracts with the fashion lines, Kendall even had to ask permission for taking a photo with her younger sister. "Am I not supposed to? Should I not take a photo with her?" Kendall asked. They were then allowed to take one photo together before going their separate ways.

Kylie who was scheduled to do an interview on the red carpet addressed her anxiety. "I totally understand that Kendall has these work obligations, but I'm getting super nervous and anxious about doing these interviews," Kylie confessed. "I really wish Kendall was going to be with me."

"I like, have a few seconds before I faint," said Kylie while walking down the red carpet to the interview spot. Her publicist who led her to a reporter convinced Kylie that she wouldn't be asked about her lips and her dad's, now Caitlyn Jenner, transition.

However, Kylie was totally nervous right in front of the interview spot as saying, "Wait, no. Now I feel too sick. No, I feel like I'm really gonna faint. No, I don't want to." She subsequently tried to move away from the interview spot.
