Kylie Jenner's family is reportedly concerned about her relationship with rapper Tyga.

When the 17-year-old posted a video clip, in which she appears to be mumbling she is "high as f**k," to her Snapchat account on May 6, many speculated that she was using marijuana. 

HollywoodLife.com recently reported that Kylie's mother Kris and older sister Kendall were unhappy. They supposedly believe that she could easily go too far with her partying.  

A source said Kylie's behavior has been affected by rumored boyfriend Tyga. The source even went as far as saying the reality star gets "wild from time to time." 

"Kylie is young, lives in L.A. and dating a rapper -- so it isn't unusual for someone in her position to be partying the way she does," the source continued. 

Although the teenager took to her Twitter account on May 10 to slam the rumors of drug use, one of her friends revealed to People the notorious clan is "worried" that the "Ayo" rapper has a negative influence on her decision-making.

"A lot of Tyga's friends are enablers," the friend reportedly said. "That makes her mom the most nervous. She doesn't want Kylie getting off track."

The friend also pointed out that Jenner and 25-year-old T-Raww have kept their romance secret since last September because she is still legally a child. The "Keeping Up with the Kardashians" star supposedly plans to move out into her own Calabasas mansion "the second" she turns 18 on August 10, the friend added.
