Her fiancé's name is Bracy Maynard, and he's known The Bachelor alum since she was 12, PEOPLE confirms exclusively.
The single mom, 32, first introduced her son to Maynard five years ago, when Ben was 3.
And what does Juan Pablo Galavis think of Oteri's news?
"At the end of it all, I’m very happy that Renee found someone and want to send her my congratulations," the current Bachelor wrote in his latest PEOPLE blog. "I hope to be invited to the wedding some day."
Galavis previously wrote that "letting Renee go was very difficult" as "she never tried to show me something she was not."
Oteri shared a photo of her stunning diamond engagement ring from Maynard on Instagram, and it certainly looks to outshine any rose.
