Kylie Jenner's rumoured relationship with Tyga has caused so much controversy, even her friends and family are beginning to worry if they're a good match.

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

In the most recent episode of KUWTK, Kylie finally admitted to cosmetically enhancing her lips after months of speculation.

"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 continued.

"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."

While with her 18th birthday just months away, the friends added that she "is obsessed with the attention and knows that acting a little scandalous here and there will keep her in the spotlight."
