It's hard to believe, but this is one controversy that the Kardashian family doesn't feel comfortable with. Apparently, Kylie Jenner's mother and sisters are concerned about her relationship with 25-year-old rapper Tyga and want her to "rethink things through" before getting any more serious with him.

According to People Magazine on Tuesday, a source close to the reality television family says that while they are not worried that Kylie might do something drastic or unbelievable with Tyga, they are worried about the influence that he has on her.

A source close to the Kardashians tells the site, "A lot of Tyga's friends are enablers. That makes her mom the most nervous. She doesn't want Kylie getting off track."

And even though Kylie and Tyga have managed to keep their relationship drama free (for now) parents Bruce and Kris Jenner are worried about what's yet to come, including a possible nasty custody battle between Tyga and his baby mama, Blac Chyna, over their 2-year-old son, King Cairo.

The insider added, "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."

For now though, the only thing that Kylie seems to be most concerned about is her appearance, or at least her ever-changing one.

"She's become a perfectionist because she feels like she needs to be just as sexy as her other siblings, specifically Kendall and Khloé," the pal says. "She doesn't feel inadequate next to them, but she's willing to do whatever she can to herself to make her feel like she's looked at by the public in the same way."
