They are simply unstoppable -- not enough with their popular reality television series, clothing collection and cosmetics line, the sisters Kourtney, Kim, and Khloé add their latest range of eyewear to the Kardashian Empire.

The Kardashian trio has been very successful with their fashion range for Lipsy, which broke all of the high-street brand's shopping records, as well as their several fragrances and beauty products.

Part of their thriving Kardashian Kollection, the sisters have came up with a line of four gold plated aviator glasses embossed with the KK emblem. Each limited edition pair, which includes both reflective and non-reflective lenses, will cost $250.

And who needs a model when they can represent their products themselves? The Keeping Up with the Kardashians reality stars themselves proudly rock the fancy shades on the ad campaign for their new products.

In addition, the sisters are already working on their next project, which is childrenswear. Named as Kardashian Kids, the clothing line features a lot of animal prints, tutus and items that are all marked with the letter "K."

Kim Kardashian previously hinted her family's childrenswear upcoming launch back in November with MTV. "I think a baby line is what's next for us," she said. "We definitely would have a lot of experience with what we would need to make that line a success and we're excited about it."

Kardashian Kids also has its own Instagram account and Twitter page. "Couldn't be more excited for @kkidsofficial. Coming soon!" Kris Jenner tweeted. She also posted the new company's logo to her Instagram with the caption following, "Imagine that!!!! So excited @kardashian_kids #itsabouttime!"
