And now, new photos have emerged as the Keeping Up With The Kardashians star steps out with a huge diamond on that finger and it's got fans speculating a secret engagement between the two!
The pictures which were obtained by Daily Mail, show Jenner, 20, sporting a double diamond band around her finger.
Jenner and her famous beau first began dating in April 2017 and welcomed their first child, Stormi, together in February this year.
While the beauty is yet to address the rumours, she has since helped her man celebrate his 26th birthday by ordering him a family-themed cake which included iced figurines of themselves and their baby daughter Stormi while riding a rollercoaster.
