We'll see Kylie walking down the street one day holding a newborn and that'll be our confirmation.
Although Kylie didn't say anything in the vid, the camera pans to her left hand on the steering wheel and her ring is pretty obvious. A noticeable glistening addition to her engagement finger couldn't be missed.
Kylie revealed her new ring in a Snapchat video she shared on the drive over to Kim's shower.
Of course, Ky know's what she's doing, with the ring clearly on her wedding finger, which does absolutely nothing to silence the rumours.
She's been keeping a low profile ever since - but fans are going mad with their theories and now suspect she and Travis could be planning to tie the knot.
Jenner is reported to be having a baby girl, though it is still unclear how far along the Lip Kit queen is in her pregnancy. Kylie has been subtly hinting at at the news through her social media posts, but momager Kris Jenner has made sure that her daughter's big news is only released when she's ready.
