Kylie Jenner is getting candid about a scary complication she had while pregnant with her and ex Travis Scott’s son, Aire.

“I have had chronic back pain for three and a half years. It’s just starting to get better,” the Kylie Cosmetics founder explained on the “Therapuss with Jake Shane” podcast Wednesday.

“But my son, my last pregnancy, it really took me out,” she added.

Jenner shared that 12 weeks into her pregnancy, she woke up one day and was unable to walk.

“I couldn’t leave my bed anyway because I was in so much back pain and sciatica pain,” the reality star recalled. “And lots of things were happening with my vagina. I was three centimeters dilated for like a month and a half, two months — the baby was falling out.”

Jenner’s doctor then put her on bed rest, which she was disappointed by.

“I was in the best shape of my life for that pregnancy,” the mom of two confessed. “So, I really had high expectations. I really wanted to work out. I gained 60 pounds with my daughter.”

Jenner revealed she was 200 pounds when she gave birth to daughter Stormi, now 8, in 2018, and 210 pounds when welcoming Aire in 2022, now 4.

“I gained like 65 pounds with my son,” she noted.

Podcast host Jake Shane asked Jenner, 28, what she “was craving” during her pregnancy with Aire, to which the beauty brand mogul replied: “Everything. I ate everything.”

“I ate a pint of ice cream every night,” she elaborated. “Rainbow sherbet. I had lots of ice cream. Just lots of carbs. Bagels. In the beginning, my nausea was horrible with my son. So, if I didn’t eat, it’d be really bad.”

As for which pregnancy was easiest, Jenner revealed that “the first one … was a breeze.”

The “Keeping Up With the Kardashians” alum was just 19 years old when she welcomed her first child with Scott, 35.

While speaking with Shane, Jenner admitted she was “freaking out” about becoming a teen mom.

“Yeah, I was freaking out. I was really scared to tell my parents,” the “Kardashians” star shared.

“And then I told my mom. No one was angry at me. It was a crazy time,” she recalled about the reaction she got from her parents, Kris Jenner and Caitlyn Jenner.

During her pregnancy with Stormi, Kylie stayed completely out of the spotlight, despite growing public speculation that she was expecting.

While carrying Aire, Kylie didn’t hide her pregnancy but opted to keep a lower profile.

Kylie and the “Sicko Mode” rapper split in 2023, with the Khy founder moving on with Timothée Chalamet by that April.

In March, the Hulu star opened up about her ideal timeline for having more children while chatting with Vanity Fair.

“In the last years of my 20s, I want to focus on just me, my businesses, my work, traveling with my kids [and] enjoying my kids,” she detailed. “And then, I do want to have more kids.”

For Chalamet’s part, the “A Complete Unknown” actor, 30, teased that kids “could be on the radar” during a 2025 interview with Vogue.

During the interview, the Oscar nominee made it clear he keeps his relationship with Kylie ultra private, not out of “any fear,” but because he doesn’t “have anything to say.”
