Kris Jenner went a "little crazy" when she found out her youngest daughter Kylie had got lip injections. The 59-year-old matriarch has admitted she didn't give the 18-year-old reality TV star permission to undergo the non-surgical cosmetic procedure to plump up her pout and was fuming when she discovered she'd gone behind her back. Speaking to 'Access Hollywood' about Kylie's lip procedure, she said: "I get a little crazy - and I think that is what no one sees - and I do have definite thoughts and ideas on what she should do, you know, at a really young age." Kylie was forced to reveal she'd been having temporary lip enhancement injections on an episode of 'Keeping Up With the Kardashians' in May after the #KylieJennerChallenge, which saw young fans attempt to mimic her full-lipped look by sucking on the rim of a cup, went viral.
