Kylie Jenner may be the baby of the Kardashian/Jenner family, but she's all grown up now. The 17-year-old is starting to move into her new $2.7 million mansion in Calabasas, Calif., People reports.

Jenner said she would move out of her mother Kris Jenner's house as soon as she turned 18, but she's not going too far. Her new 4,900-square-foot mansion is just a block away from big sisters Khloe and Kim Kardashian.

Kylie enlisted Khloe's help and the two posed for a sister selfie while they moved furniture into Kylie's new house. The photo shows the girls wearing leggings and sneakers, and Kylie wrote "Don't you wish your move in crew looked like mine" in the caption.

Big sister Khloe reposted the photo, and added the caption, "We're finally neighbors!!!! Moving day!!!!"

But Kylie still needs her mom's help and recently told E! News that Kris stepped in and offered her expertise during the remodeling process of her daughter's new home.

"My mom is so amazing at this, if I didn't have her I would not have as beautiful of a house," Kylie told E! News. "She's made it very easy." 

Kylie's move was a family affair. All the furniture she's moving in are hand-me-downs from her older sisters and her mom, which will give her place an old familiar touch.

"Before I bought anything, they just gave me a bunch of stuff they had in storage and a bunch of old stuff," she said. "So most of my house is all them."
