Amid dating rumors surrounding Kylie Jenner and Tyga, the bedroom rule for their trip to Europe was finally revealed.

"Kylie has assured both her parents she and Tyga have had separate rooms," a source revealed to HollywoodLife.com. "Kylie even calls to check in with both Bruce and Kris everyday since she's been with Tyga."

In addition to using separate rooms with rumored rapper boyfriend, the 17-year-old apparently reports everything to her parents, who seemingly trust the young couple.

"Everything is on the up and up from what Kylie and Tyga are telling Bruce and Kris. And they seem fine with it so let them be," the source continued. "Bruce doesn't at all think that his little girl and Tyga are sexually involved."

The source also insisted that the pair's trip is simply "predicated around Tyga's touring and hitting up clubs and promoting himself and his music" and "educational" for Kylie's music career.

"Tyga believes Kylie is on the verge of being a huge breakout Pop star and that she should see firsthand what it's like to live that life," the source added. "He's testing her."

Meanwhile, it was previously reported that the former Olympian was worried about his daughter's highly publicized dating rumors, to the point that he had to warn T-Raww.

"Bruce ain't no joke and he ain't no punk either," another source said. "He told Tyga straight up, 'That's my baby. If anything happens to her, you're a** is mine.'"

However, during her guest appearance on KIIS FM's "On Air with Ryan Seacrest" last week, Kris Jenner confirmed that her youngest child is currently single. "

Kylie isn't dating anybody," she told the host. "[Tyga is part of] this whole little group of kids who have been around forever -- and I call them kids because relatively speaking, they kind of all travel as a pack and they enjoy each other's company."

According to the Kardashian matriarch, the reason that Kylie and T-Raww are so close is because they live in the same neighborhood.

"[Tyga] used to live across the street for a long time, and now he lives next door to Khloé," she said.
