‘Big Brother’ Stars Jessica Graf and Cody Nickson Are Engaged — Watch the Sweet Proposal!

She said yes! Jessica Graf and Cody Nickson have gone from certified showmance to engaged couple IRL. The Big Brother star popped the question to his girlfriend (and former co-star) on Feb. 13 while on a romantic hike— and luckily for fans it was all caught on camera.

"I’m running to get ahead of Jessica. She’s going up Runyon Canyon right now. I’m gonna meet her at the top of the hill and propose," the former Marine says in the video posted to the couple's YouTube page. Once Cody gets to the top, he gets down on one knee and waits for the brunette beauty, who instantly starts crying. The couple even has a small cheering section to congratulate them following the proposal.

"I found my true love, I got the ring, only one thing left to do," Cody wrote on Instagram following the engagement. "Thank the Lord, thank you to everyone who prayed for us, thank you BB for casting us so we could meet, thank you Joey Hamra @hamradiamonds in NYC for helping me design the perfect ring. Thank you Lori for helping keeping it a secret since I’m with Jess every waking moment. Thank you to my sisters and mom and dad for making Jess family… we are blessed."

Jess also gushed about the engagement on social media, writing, "I said yes! On Tuesday, February 13th my best friend asked me to marry him. He’s made my dreams come true every day since we met! I love you [and] there’s no one else in the world for me. You’re my person and I thank God for you coming into my life!"

The couple met and fell in love on Season 19 of the reality competition — joining fellow Big Brother couples Daniele and Dominic, Jeff and Jordan, and Rachel and Brendon — and are currently competing on The Amazing Race. However, viewers will have to tune in to CBS on Wednesday, Feb. 21 at 10 p.m. to find out if they win. Congrats to the happy couple!
