'Big Brother' Season 20 Finale Ends With a Shocking Live Marriage Proposal

By

Never underestimate the twists and turns you'll experience while watching Big Brother!

On Wednesday's heated Big Brother 20 finale, the drama of the jury's final vote for the season's winner was totally overshadowed when Chris "Swaggy C" Williams had a chance to reconnect with Bayleigh Dayton after weeks of being apart.

Swaggy C, who had been eliminated early in the competition, had struck up a meaningful romance with Bayleigh in the short time they shared the house together. During Wednesday's finale, the 23-year-old day trader managed to express just how enamored he still was, despite weeks of separation.

"I'm still very much in love with Bayleigh, 100 percent," Swaggy C admitted when asked what it was like to see her after 76 days. He also revealed that a lot has been going on in the real world while Bayleigh was competing.

"I went to your parents' wedding anniversary, and I've spent a lot of time with them," Swaggy C revealed. "I've played golf with your dad every single weekend."

Swaggy then stood up and walked over to Bayleigh, taking her hands and asking her to stand up with him.

"Sitting at home and watching you tell millions around the world how much you love me,  and wanted to be with me forever, made me realize that 'girlfriend' wasn't enough, honestly," he said, before dropping to one knee and pulling out a diamond ring.

"Shut up!" Bayleigh said in stunned, excited disbelief.

"I don't care about any other girl in the world. I want you and only you. I don't really know what my future holds, but I want you in it," Swaggy C said. "Will you marry me?"

"Yes, yes, yes!" Bayleigh exclaimed while jumping up and down and kissing Swaggy C. Needless to say, the other members of the jury couldn't contain their excitement.

ET's Brice Sander caught up with the newly engaged couple backstage after the finale, and Bayleigh opened up about how surprised she was by the exciting proposal.

"On a scale of one to 10, maybe a 25? I was completely blindsided," she said. "I never thought that that was even going [to happen] and you can't make assumptions like that."

As for whether or not she was sure she she was going to say yes, Bayleigh said it was actually harder to let Swaggy C finish asking the question.

"I didn't even need to see the ring! As soon as he got on his knee I was like, 'Oh my god, yes! Please!' But that's like, aggressive, so I had to keep it together, you know? Just for a second," she recalled.

As for the live proposal itself, Swaggy C said the plan came together in just the last four days.

"I had the ring two weeks ago, but I was like, 'I'm gonna do it later, like, for Christmas,'" he said, before explaining that he decided to move up his plans after he couldn't stop dreaming about the proposal. "So I was like, 'You know what? I'm just gonna do it now.'"

Now that they're engaged, the couple have already settled on the idea of moving into together right away, and they already know where they want to live.

"We're moving to L.A.," Bayleigh declared. "That's the plan for now."

While they were candid and open about their love and engagement, the two played super coy about pregnancy rumors. "We're not going to really comment on that," Swaggy C said sheepishly when asked about the speculation and gossip.

"Yeah, we don't really wanna talk about that," Bayleigh chimed in.

"Not right now, at least," Swaggy C added.

Congrats to the couple on their new engagement!
