In what could be dubbed the cutest rose ceremony we've seen to date, the hunky astrophysicist professed his love for the chemical engineer, revealing he can't wait to spend the rest of his life by her side.
It wasn't quite the happy ending runner-up Abbie Chatfield was hoping for, however.
From the moment Matt and Chelsie laid eyes on each other, it was clear there was a spark and some serious chemistry as the two shared a passion for science.
During her red carpet arrival, the Victorian beauty gifted Matt with a temporary tattoo of the chemical formula for "oxytocin" — the love chemical.
To her disbelief, he understood the meaning behind the sentimental present!
"I can't believe he is smart," Chelsea told the cameras after their encounter. "That is so exciting. I actually didn't think he would be able to understand what I was talking about at all!"
And the hunky astrophysicist admits he was starstruck from the get-go.
"It feels like she's reading the handbook of what Matt's looking for in a relationship," he gushed during their first single date. "Every time with Chelsie, she just makes me happy. We have a ridiculous amount in common, and it's just so easy and natural when we're together."
And now they've got the rest of their lives to nerd out together in scientific bliss!
Ugh, we love these two...
