Blake, who previously appeared on Clare Crawley's and Tayshia Adams' seasons of The Bachelorette and joined Katie's late, was one of the final two suitors along with Justin Glaze after fellow contestant Greg Grippo left the show. But after Katie professed her love for Blake on their fantasy suite date, she knew he was the one and sent Justin home.

After some grilling from Katie's aunt Lindsey and a few pre-proposal nerves, Blake ended up getting down on one knee and presenting Katie with a three-carat diamond ring. Of course, she said yes.

"I truly actually did not think he was going to propose," Katie told Good Morning America in an interview that aired Aug. 10. "And so then when he actually got down on one knee and proposed, my reaction is actual shock."

Now that her Bachelorette journey is over, Katie is looking forward to her next chapter with Blake. "At some point, there's certainly a wedding, " she said on GMA, "there's no doubt about that."
