The most notorious Hills bachelor is no more: Brody Jenner is engaged!

The MTV alum -- who famously "dated" Lauren Conrad and romanced Kristin Cavallari, to name just a few lucky ladies -- has announced that he popped the question to his longtime girlfriend Kaitlynn Carter.

"On May 4th 2016 I got engaged to my lover and my best friend @kaitlynn_carter," the soon-to-be husband captioned the sizzling photo of the happy couple, sitting poolside while on vacation in Indonesia. "I couldn't be more in love with this woman and I can't wait to spend the rest of my life with her."

The future Mrs. Brody Jenner -- who began dating the 32-year-old in 2014 -- shared the same snapshot of the lovebirds and added, "this trip has been memorable for many reasons... happiest girl in the world!!!"

Fittingly, Brody's mama Linda and Kaitlynn's parents were able to celebrate with their kids shortly after the milestone event occurred.

"If we look happy it's because we are!" Brody's mama wrote along with the image above. "CONGRATULATIONS to @brodyjenner & @kaitlynn_carter who got ENGAGED in Nihiwatu! #Family #Love"

And, of course, Spencer Pratt offered his well wishes to his buddy (the complete opposite of when he had "nothin' to say" to Brody during that tense phone call back on Season 2).

Be sure to leave your congratulatory messages to Brody and Kaitlynn in the comments -- and since a Brody/LC happy ending was not meant to be, relive their first date during Season 2 of the long-running series for a humorous rewind:
