Nathan asked Jenelle for her hand in marriage while on a special vacation in St. Thomas, and she quickly shared some snapshots of her beautiful brand-new bling.
"Oh man, someone's engaged," J posted on Instagram, along with a closeup of her stunning sparkler.
The proposal wasn't unexpected: The 23-year-old's beau recently told his sweetheart -- and the Twitterverse! -- that she wouldn't have her last name for much longer and they did shop for rings. Now, in the not-so-distant future to boot, she'll be Mrs. Griffith! We do know two pretty precious ring bearers (Jenelle's firstborn Jace and their boy Kaiser) and a perfect flower girl (Nathan's daughter Emery) to round out the special wedding party.
The pair's relationship has been chronicled throughout the past few seasons of the hit MTV series -- from meeting in June 2013 and falling head over heels for each other to excitedly welcoming their first child together. Both Jenelle and Nathan have been outspoken about their desire to one day be living together in holy matrimony.
"We want everything to be perfect," Nathan reflected last spring during an interview with MTV.com about tying the knot. "We want all the kinks worked out in our relationship; we want everything to just be smooth, so when I do ask [her] to marry me there's no second thought or [her] saying yes just because of the ring. [It's because she] actually wants to be with me for the rest of [her] life." And now, that time has come!
Send your heartfelt congrats to the duo below, and take a fond look back at an unforgettable moment in their lives: Kaiser's birth.
