Jenelle shared the news via an Instagram post, which was a close-up of the ring and the caption "Oh man! Someone's engaged!"
Back in April, Jenelle had revealed that they'd already talked about engagement, but that Nathan was waiting for just the right time.
"He's says, 'Look, I'm going to propose to you, it's going to be soon, it might be before Kaiser, it be after Kaiser [their son], but I don't want you to have any idea on when it's going to be, and I don't want to feel like you're desperate and need to just take the ring or say yes to make me happy. I want you to say yes because I know that you love me," she revealed to Wetpaint.
Well, it looks like the right time finally came during their vacation to St. Thomas. Jenelle hasn't provided any details about the proposal yet, but we know that when she and Nathan went to dinner, she wasn't wearing a ring and by the end of the evening, she was showing off her stunning sparkler.
