These days, "Real World" and "Challenge" vet Devyn Simone is helping folks navigate the online world of dating -- but the MTV cast member will no longer need any assistance landing Mr. Right because she's now happily engaged!

The "Battle of the Seasons" and "Free Agents" finalist -- who memorably had a romantic connection with fellow competitor Big Easy -- tweeted her big relationship news shortly after accepting her beau's proposal. Fittingly, Dev made a stupendous reference to her "Challenge" days when revealing her life-changing update.

"I've been enjoying my engagement-moon with my new fiancé! He proposed at the top of a mountain. Oh the irony," the Missouri native posted, along with a collage-style photograph showing off her new bling. Well, this autumnal hike doesn't look nearly as treacherous as scaling a sand dune in Namibia or climbing a volcano in Chile...and she's with her husband-to-be!

Shortly afterward, the congratulatory messages for the future Mrs. began flowing in from some familiar faces:

Offer your well wishes to Devyn and her fiancé in the comments!
