Looks like the Kylie-Blac Chyna feud is not over! While the two have been exchanging jabs at one another for quite some time now, Blac just took it to the next level by teasing Kylie Jenner's famous pout. Tyga's ex-girlfriend Blac Chyna and the mother of his son, King Cairo, subtly dissed his rumored new girlfriend, 17-year old Kylie, by joining (and mocking) the #KylieJennerLipChallenge.

Blac did not have to write a lot to let her followers know what exactly it is she was getting at, so she simply kept the photo's description to a minimum. The photo, which showed her lying down on a carpeted floor and sporting big, red Wack-O-Wax lips, was captioned with just the lip emoji.

She then posted another picture of just the lips and captioned it, "Will be available on @88_fin." 

And While Blac's post was obviously a dig at the youngest Keeping Up with the Kardashian star, other girls, and boys too, have sincerely attempted to copy Kylie's luscious lips in a manner, which medical experts say are unsafe. 

A crazy trend that's been going on right now has teens inserting their lips on shot glasses or bottles and sucking in the air inside just to copy Kylie's controversial pout. While some lips look incredibly full, some lips simply became swollen and bruised.

Medical experts and doctors have spoken up about this method and said that this DIY procedure will not only cause pain, swelling and bruising but can also cause permanent damage, disfigurement and scarring if repeated. 

Even Kylie does not recommend the method! She took to her Twitter account and wrote on Tuesday afternoon that she's not in any way encouraging people, especially young girls to copy her look. Instead, she wants people to be themselves and to not be scared of having fun and experimenting with their looks.
