Kylie Jenner seemed to be all out in supporting her older sister Kendall who walked at the Victoria's Secret Fashion Show this week.

According to an insider, there's allegedly not a trace of jealousy on Kylie's part as her sister and "Keeping Up With The Kardashians" co-star achieved something that other models can only dream about.

"You'd think having a older sister as a Victoria's Secret model would make you jealous, but Kylie is far from that," a source told Hollywood Life. "For one, it's not what Kylie would want to do, she has other ambitions like acting that she wants to achieve, but also she wants the best for Kendall."

"She knows how much Kendall wanted to be a part of the Victoria's Secret Fashion Show, and she can't wait to see her strut her stuff on the catwalk," the source close to the sisters continued.

Some Hollywood watchers disagree over the source's claim that modelling is "not what Kylie would want to do." After all, why would she walk in her brother-in-law Kanye West's fashion show if she doesn't want to be a model?

There have been previous rumors that Kylie is purportedly jealous of Kendall's looks and career.

In a "Keeping Up With The Kardashians" throwback video posted by Hollywood Life in a separate report, then 13-year-old Kylie was seen mocking Kendall's dream of being a model.

In the clip, Kendall showed her momager, Kris Jenner, a lookbook of her photos. The momager said she make some calls to help her daughter jumpstart her modelling career.

This earned a fuming reaction from Kylie.

"If you want to help her model, you can help her model," Kylie told Kris Jenner. "But it's just going to get to her head and all of us are going to be in her little throne listening to her."

"We're going to be like, 'Oh my God! You're right! You're, like, the coolest in the family because you model when you're 14!'"

However, it could be argued that Kylie has been a very young teenager then, and she has grown a lot more mature over the years.
