Keeping up with his ex.

Travis Scott seemingly made a wild reference to ex Kylie Jenner’s breast implants on Don Toliver’s new song, “Rosary.”

“She look at me like Scotty, man, that S on my chest (Scott, Yeah) / Forty-four five C, the way they sit, I need to test (Straight up),” he rapped, referring to a breast implant size measurement that is estimated to be between a D and DD cup, per London’s Centre for Surgery.

“Hate it most when you be out, I swear it’s cool when you do less / Don’t sweat it, she get me right tonight, she can be my medic,” the “Sicko Mode” rapper (real name: Jacques Webster Jr.) added.

Page Six has reached out to Jenner’s rep for comment but did not immediately hear back.

The “Goosebumps” emcee’s cryptic lyrics came months after Jenner revealed the exact details of her highly sought-after boob job.

When a fan questioned the mom of two on how to get her “perfect, natural” boobs to “sit like that,” Jenner responded, “445 cc, moderate profile, half under the muscle!!!!! silicone!!!”

Additionally, the Kylie Cosmetics founder also provided the name of her Beverly Hills, Calif., doctor: Garth Fisher.

“Hope this helps lol,” she concluded her candid confession.

Jenner previously denied getting any work done on her breasts.

“I haven’t gotten breast implants! Everyone is obsessed with that,” she wrote on her website in 2015. “Truth is, as I’ve gotten older, I’ve gained 15 pounds and my body has changed; I’ve definitely filled out.”

However, in 2023, she made headlines for admitting to getting a boob job at age 19 on an episode of her family’s Hulu show.

“I wish I could … do it all differently. Because I wouldn’t touch anything,” she said.

Jenner explained to BFF Anastasia “Stassie” Karanikolaou that she wanted to be an “example” for her eldest child, Stormi, 8.

“I’d be heartbroken if [Stormi] wanted to get her body done at 19,” the beauty guru shared.

Scott, 34, and Jenner, 28, dated on and off from 2017 to 2022.

The exes share daughter Stormi and son Aire, 4.

The “Keeping Up With the Kardashians” alum is now dating actor Timothée Chalamet.
