Kylie Jenner might be getting a lot of attention for her new "look" these days, but it looks like she's also caused quite a controversy at home, too. There's a new report that says Kylie's sister Kourtney Kardashian is none to happy that Khloe recently got lip injections, as she thinks she now looks like a freak "just like Kylie."

According to OK! Magazine on Monday, Kourtney doesn't approve of the fact that many of her sisters are using botox, injections and plastic surgery to enhance their looks.

A source close to the Kardashian family said that Kourtney "wasn't pleased with Khloe getting her lips done, especially after the embarrassment Kylie's caused. She is really upset that she would do something so stupid."

What's more, Kourtney supposedly thought Khloe's natural lips were her "trademark asset" and is "really angry she's done this and think it's a big mistake."

The insider continued, "Kourtney and Khloe were always on the same page in terms of natural beauty and not going crazy with surgery like Kris and Kim have done. They don't want to encourage Kylie and Kendall to be like that, but now it's way too late for that."

For months, there has been speculation that Kylie might have gotten lip injections, which is a rumor that she has denied. Kylie's lips look much bigger than they did last year, but the 17-year-old insists that her new look is nothing more than a little makeup magic and contouring.

So far, neither Kourtney nor Khloe have made any comments about her supposed lip injections.
