Despite only going public with their romance back in August when Kylie turned 18, it's thought that Tyga thinks their romance could last a lifetime.
A source told E! News: "Tyga wants to marry Kylie eventually. They discussed it later down the line once Kylie gets a bit older. They are in a very happy place."
And it sounds like Tyga is totally besotted! The source continued: "He thinks she is the most beautiful lady in the world and always tells her that. Tyga spends lots of time at Kylie's new home.
"Their favourite thing to do with each other is just laugh, watch a movie, cook some food and just chill out. They are both very low key people in their environment. Tyga is super close with Kylie's family and loves hanging with them."
The couple certainly seem pretty loved up right now, whether it's looking all fancy attending Kris' 60th birthday celebrations together or just running errands together (and Snapchatting the whole thing too, of course).
Tyga even joined the entire Keeping Up clan on their St Barts holiday, and you don't get much more serious than that!
However before anyone starts wondering what uh-mazing manicure Kylie will go for to show off her sparkly diamond ring (just us?) the reality star has previously denied she'll be tying the knot in the near future, tweeting: "Not planning on getting married anytime soon."
Reckon Kylie was bluffing or is this source just too romantic for their own good?
