BRAND NEW ON E!
Or the ways of their world, anyway!
Asked during an exclusive sit-down with E! News if getting ready for their son's arrival included making certain changes to his lifestyle, particularly in the marijuana-use department, Khalifa told us, "Not as far as that goes."
"I think it's all about how you're raised with it," the Rolling Papers rapper said. "Before there was a much more negative outtake on it. You know, pot and what it can do, and the effects of it."
"Of course," he added, "I'm not going to be smoking right there over the baby, because smoke in general and being high is not good for a kid. None of that. But definitely he's going to know what it is—and he'll know the difference between being a child and not being able to use it and being an adult and knowing how to use it."
Added Rose, who's well into her third trimester (and who sweetly held hands with her man throughout the interview): "It's just like alcohol, basically. That's how I feel about it, you know. When you're a kid, you know that you're not supposed to drink alcohol, that it's for adults and that's it.
"Our son is just going to know that daddy likes to smoke."
Rose also revealed that she's planning to have a natural water birth at home. "Whatever she wants to do," Khalifa said. "I facilitate that."
"I'm looking forward to the pain, actually," Rose said. "My family thinks I'm crazy, but I want to feel the pain and I want...the end result, just holding my baby and going through all that for him."
The mom-to-be said that, while Khalifa's out on tour a lot, when he's home he's "100 percent" there for her.
Rose also shared a key piece of parenting advice her future mother-in-law gave her: Don't forget about Wiz once the baby comes!
"I said that I wanted to have the baby in the room with us until he's, like, 14," the model joked, "and his mom is like, 'No, he needs to have his own room.'"
