The 19-year-old "Keeping Up with the Kardashians" star and 25-year-old rapper showed off their ink on their respective Snapchat accounts Monday following dating reports.
Jenner got a tiny butterfly inked above her ankle on the back of her right leg, while Scott got his in the same place on his left.
"Legit happiest day of my life," he cryptically tweeted the same day.
Fans speculated the tattoos reference Scott's song "Butterfly Effect," which is believed to be about Jenner. The singer shared a photo on Instagram of Jenner on a private plane in May with the caption "BUTTERFLY EFFECT."
"Need ya love, not a need it is a must / Feelin' stuck, you know how to keep me up," the song's lyrics read.
Jenner and Scott were first linked in April following the reality star's split from Tyga.
The pair were spotted having dinner and visiting the set of DJ Khaled's new music video in Miami last week.
