The mother of three serves up all kinds of body goals in the accompanying photoshoot, flaunting her enviable abs.
No topic is off limits in the magazine interview, including her complicated relationship with her ex -- and the father of her three children -- 33-year-old Scott Disick. Kourtney appears to have made peace that the pair isn't together anymore following their breakup last July after nine years together, but leaves the door open for the future.
"The idea of having my family together is amazing, but it's not the way things ended up," she acknowledges. "They may end up there. I'm not sure. To me, it's in God's hands. If it's meant to be, then things will line up."
"We definitely tried for a long time," she adds. "But relationships are exhausting! Being able to focus on the kids and me right now is good. We say to each other all the time, 'I'm the coolest ex-girlfriend/baby mama you could ever ask for!'"
However, she's unsure about how either of them will react if one gets a new significant other.
"That's what I don't know," she admits. "We're so not there yet."
Of course, their children always come first. Kourtney -- who says she could actually see herself with six kids -- admits 6-year-old Mason, 4-year-old Penelope, and 1-year-old Reign can't watch Keeping Up With the Kardashians because some of the content is "not appropriate."
"They've seen some of it, but no," she says when asked if her kids watch the E! reality show that made the family famous. "I was in the shower, he [Mason] woke up, and it happened to be on. He was like, 'Who is Blac Chyna? And Kiki [Kim] showed Larsa [Pippen] her vagina!' I was like, this is why they don't watch the show. Some of the content is just not appropriate."
Still, the eldest Kardashian child will always have her family's back. Kourtney touches on her sister Kim's decision to post explosive Snapchats of husband Kanye West calling Taylor Swift about his controversial song "Famous" last month, and not surprisingly, she backs her up 100 percent.
"It's her husband, and he's family," she explains. "The truth is the truth, so why not let it be known?"
