Bad Influence! Kylie Jenner's Mom Kris 'Nervous' Rumored Boyfriend Tyga Brings The 'Wrong Crowd' -- Source Calls His Friends 'Enablers'

They haven't announced an official romance, but Kylie Jenner and rapper Tyga are doing little to hide their relationship.

While Jenner's Kardashian sisters were reportedly supportive of their baby sibling at first, a source close to the 17-year-old has revealed to People Magazine that her family recently became concerned with the influence of the rapper's entourage.

"A few family members are worried about where she's headed," the insider shared, especially "momager" Kris.

"A lot of Tyga's friends are enablers," the source added. "That makes her mom the most nervous. She doesn't want Kylie getting off track. Her parents know she is going to date who she wants, but they are worried he will have a negative impact on her decision-making."

Jenner has come under fire frequently in recent weeks, first for admitting that she has lip fillers to enhance her pout and later posting a Snapchat video in which she allegedly declared herself "high as f*ck."

But Jenner has carried on with her Tyga relationship. The high school senior was recently spotted backstage at one of his performances.
