Congratulations are in order for Teen Mom 2 star Kailyn Lowry! The 20-year-old and her boyfriend of one year, Javi Marroguin, are engaged! "It's true. We’re engaged," an excited Kailyn tweeted on Sept. 15, along with a photo of her diamond ring — which she later deleted. “Thank you all for being so supportive! No concrete wedding plans yet, but hopefully in the near future.” Kailyn became a fan favorite after appearing on MTV’s reality series 16 and Pregnant. Once cast on Teen Mom 2, viewers got a closer look at the Pennsylvania native living as a single mom, trying to balance school and two jobs in hopes to provide her 2-year-old son, Isaac, with a better life. “As [Isaac] gets older I'm getting more anxious about settling down with someone,” Kailyn said last year. “Like a real family.” Looks like she got her wish.
