Shocking live proposal on 'Big Brother' finale and Twitter wasn't here for it

Kaycee Clark is officially the winner of Big Brotherseason 20 and its $500,000 prize!By a vote of 5 to 4, which ironically came down to Bayleigh Dayton's vote, Tyler Crispen became the runner up, but was also announced as this year's "America's Favorite Houseguest," which earned him a total of $75,000.

However, Clark and Crispen weren't the only ones who scored big Wednesday night, because there was a surprise proposal!When host Julie Chen took time to grill this season's three showmances, Chen asked Bayleigh Dayton, "What's it like to see Swaggy after so much time apart?" Dayton blushed and answered, "He's beautiful. Literally obsessed." And when Chen asked Chris "Swaggy C" Williams what it was like seeing Dayton after all of their time apart, Swaggy told Chen, "I'm still very much in love with Bayleigh, a hundred percent." Swaggy then turned to Dayton, and said, "There's been a lot of stuff that's been going on in the real world that you haven't known, that I went to your parents' wedding anniversary. I spent a lot of time with them. I played golf with your dad every single weekend. There is a lot of stuff I want to tell you. I'd rather tell you standing up than way across the stage." So, Swaggy got out of his seat and walked across the stage, which immediately turned everyone's heads. Swaggy then took Dayton's hands and asked her, "Remember on day ten I did this exact same gesture. And you yelled at me because you said, 'You're not a man. Take charge. If you want something, be a man and stand up.' Do you remember that? So, I asked you to be my girlfriend, and you said yeah. Sitting at home and watch you tell millions around the world how much you loved me and wanted to be with me forever, made me realize that girlfriend wasn't enough, honestly." Dayton then exclaimed, "Shut up!" as Swaggy got down on one knee and proposed to Dayton by saying, "In front of millions around the the world, I really don't care about any girl in the world. I want you and only you. And I don't really know what my future holds, but I do know I want you in it. So, Bayleigh Amethyst Dayton, will you marry me?" Dayton then jumped up and down yelling "Yes yes yes!" and everyone cheered for the newly engaged houseguests.

Congratulations, Swayleigh. But back to what should be the biggest moment of the night – Kaycee Clark won Big Brother! Cue Clark's iconic #BB20 tagline: LET'S GO!
