The love lives of the Kardashians have never been simple, but things took a slightly weird turn when Rob proposed to and had a child with Kylie Jenner's love rival Blac Chyna, who also happens to be the mother of Kylie's boyfriend Tyga's child, King.
Slightly confused? Us too.
However, the quartet of co-parents seem to be making things work, with Kylie playing babysitter to King on the regular, and now the 19-year-old is even renting out one of her lavish homes to her big brother and his new family.
Rob, Chyna, King and their newborn daughter Dream moved into Kylie's Hidden Hills mansion this week in order to be closer to Rob's family.
The make up mogul owns two other homes in the area, not including her own. That's quite a property portfolio for a teenager.
While it's not unusual for siblings to help each other out, we're sure that this move will make for an interesting episode of Rob & Chyna.
