The "Teen Mom 2" star took to Instagram on Monday to reveal that she's engaged to boyfriend Nathan Griffith.
The mother-of-two posted a photo of her gorgeous diamond ring and captioned the snapshot, "Oh man! someone's engaged."
The couple posed for a picture together before Evans revealed the big news. Wearing a long pink gown, the 23-year-old looked happier than ever alongside her hubby-to-be, who sported a black shirt, tie and vest.
Jenelle and Nathan have been dating for almost two years and have one child, 4-month-old Kaiser, together, who they welcomed back in June.
Baby Kaiser joins 5-year-old Jace from Jenelle's relationship with ex-boyfriend Andrew Lewis, and Griffith's daughter, Emery, 3, from a previous relationship.
