We've been crazy-obsessed with Emily O'Brien ever since she charmed Ben Flajnik's floppy middle-parted hair off during The Bachelor Season 16. This blonde bombshell is the tops, and she's more than moved on since being rejected by Ben and his wine-obsessed self. In fact, girlfriend just got engaged this month!

This gal took it to Instagram on June 2 (yeah, it’s been a bit, apologies Em) to debut her stunning cushion-cut engagement ring, which she got as a birthday surprise from her boyfriend, Donny! We still don't know much about Em's mysterious fiance (other than the fact that he's a huge Annie Lennox fan and is one of Duke Orthopaedics' chief residents), but these lovebirds were last spotted getting cozy over Valentine's Day in Punta Cana, and it looks like their relationship has been on the fast track ever since!

Of course, we can't forget that Emily was briefly linked to The Bachelorette's Mike Burns (they were spotted snuggling at Mike's 30th birthday party in San Diego), but they called the relationship quits due to the fact that Emily was getting her PhD in North Carolina. Because, yes, in case you forgot, she's totally brilliant.

Hear that, Flajnik? It's the sound of your heart melting into a puddle of regrets.

No word yet as to when Emily's wedding will go down (or whether Chris Harrison will be officiating....), but we're sure she'll do us all a solid and rap her vows.
