Underage Kylie Jenner has reportedly been spending "days and nights" at rumored boyfriend Tyga's house lately.

The 18-year-old, who is currently dealing with father Bruce Jenner's sex change and fatal car accident among other family issues, is "using the chaos" as her excuse to pretty much live at the "Ayo" rapper's mansion in Calabasas, California.

"She spends days and nights at a time at Tyga's mansion and even has keys and alarm codes," an insider told RadarOnline.com. "The staff treats Kylie as someone who lives at the house."

Mother Kris Jenner is apparently fine with her teenage daughter staying over at T-Raww's house, the insider said.

"With no curfew, it's not uncommon for Kylie to not see either of her parents for several days at a time," the source said. "Kris trusts Tyga, and Kylie and thinks he is a good influence on her."

Bruce, on the other hand, reportedly feels different.

"Bruce is less than thrilled with the arrangement, however he knows there is no point in fighting about it because Kylie will just do what she wants," the insider added. "Kylie does what she wants, it has always been that way. When she turns 18 in a few months, Kylie will definitely be getting her own place to live."

Similarly, HollywoodLife.com previously reported that the inseparable rumored couple has been sleeping together, claiming that the reality star has full access anytime at the "Rack City" hitmaker's place.

"She comes and goes as she pleases," a source said. "She has a key to his place and all the security codes needed to get in and out."

The source also claimed that Kylie has "her own room and bathroom" in Tyga's house.

"Her mother is fully aware of the arrangement and supports it and trusts that both Tyga and Kylie are telling the truth that no funny business is going on," the source said.
