Kai's boyfriend of one year, Javi Marroquin, popped the question on Sept. 1 at one of her favorite childhood spots, Lake Wallenpaupack. According to OK! Magazine, Javi set up a romantic scavenger hunt, and when Kailyn found the spot, Javi was there waiting — down on one knee, of course! — with her son Isaac in tow carrying the flowers.
Although we'll probably have to wait for Season 3 of Teen Mom 2 to see the engagement in its entirety, we have one little sneak peek thanks to Kailyn's new Twitter avatar.
