Kailyn Lowry and Javi Marroquin
After a year of dating, the Teen Mom 2 star, 20, said "yes" to Marroquin's September proposal. "It's true," she tweeted shortly after he popped the question. "We're engaged!" Added her beau: "I love my fiance. Couldn't even dream about the way my life is turning out to be!" The marriage will be Lowry's first; she has a 2-year-old son, Isaac, with ex-boyfriend Jo Rivera.
