The couple got matching tattoos on their body and showed off the artwork on Monday on Snapchat, Us Weekly reported.
The tattoo design of choice? The black outline of a tiny butterfly.
Kylie, 19, and Travis shared captionless photos of their tiny tattoos through the photo and video-sharing app.
The upcoming Life of Kylie star reportedly got the tattoo just above her ankle on the back of her right leg, while the 25-year-old rapper inked the butterfly in the same exact spot on his left leg.
The sweet butterfly tattoo appears to represent Travis' new song "Butterfly Effect," which many fans speculate may be about Kylie.
Travis made it seem like there's a connection between his song and girlfriend because when "Butterfly Effect" was released in May 2017, he posted a photo of Kylie exiting a private plane on Instagram with the caption, "Butterfly Effect."
"Heatin' up, baby, I'm just heatin' up / Need ya love, not a need, it is a must," the musician raps on the track. "Feelin' stuck, you know how to keep me up / Icy love, icy like a hockey puck."
Kylie and Travis' romance is clearly going strong. Since getting together, Kylie and Travis have traveled together, attended NBA basketball games, enjoyed date nights and more.
An insider told Us in early May that Travis was "telling friends that he and Kylie are the real deal."
Kylie and the Texas-born artist have seemingly been inseparable since they were spotted getting cozy at the Coachella Valley Music and Arts Festival in mid-April, just weeks after the Keeping Up with the Kardashians star ended her longtime on-again, off-again romance with Tyga and he allegedly moved out of her $6 million Hidden Hills mansion in California.
The lip kit maven's new reality show Life of Kylie is set to premiere August 6 at 9PM ET/PT on E!, so maybe Travis will make an appearance.
The network previously announced it had ordered eight, half-hour episodes of the new series that will follow Kylie's personal and professional life.
