Reality star Casey Reinhardt knew how to make a splash on Laguna Beach and The Hills alongside former costars Lauren Conrad and Kristin Cavallari, so it's not surprising that her engagement ring is one of the most dazzling we've ever seen! Reinhardt's longtime boyfriend, Sean Brown, popped the question on August 12, and she posted a sweet Instagram photo of the proposal.

But wait, it gets better -- she also gave us a look at her gigantic pear-shaped diamond with a diamond halo.

My fiancé!!!!! ❤️❤️❤️❤️❤️

Since Casey's MTV reality show days, she opened up her own bakery called Casey's Cupcakes (which look like the most glamorous cupcakes ever, naturally), and even took top honors on Food Network's Cupcake Wars four years ago. Something tells us that she's going to have a pretty spectacular cupcake tower at her wedding!

Congratulations to Casey and Sean! See more of their cute photos together from Instagram below:
