After weeks of grueling competition in the 'Big Brother' house, one houseguest is walking away with $500,000.
After weeks of scheming, deal-making, backstabbing, and grueling competition, Big Brother 20 came down to three remaining house guests duking it out for the $500,000 prize.
Kaycee Clark, JC Mounduix, and Tyler Crispen were the three ruthless competitors who managed to hang on to the bitter end, and after one final night of high-stakes, head-to-head challenges, only one could win it all.
And the winner of Big Brother 20 is....
...pro footballer Kaycee!
The exciting finale kicked off Wednesday, with the second part of the final Head of Household competition, in which JC and Kaycee had to put their memory skills and their rock climbing abilities to the test, in a timed challenge that asked them to recall trivia about past eliminations, and then climb a rock wall to place their answers at the top.
Both houseguests gave it their all, but Kaycee ended up edging JC out by a minute and went on to face off against Tyler for the chance to be named the final HOH of the summer.
For their final challenge, they faced off in another test of their Big Brother 20 trivia knowledge called Jury Oddcast. For the test, they listen to eliminated houseguests recount things that happened to them during the season, and then they have to vote on whether or not what the houseguests said was correct, or not quite accurate.
After answering every single question exactly the same, the competition came down to a tie-breaker challenge that Kaycee ended up winning, making her the final HOH -- meaning she got the chance to kick out either Tyler, with whom she had a season-long alliance, or JC.
In the end, Kaycee sent JC home after an emotional final elimination, sending herself and Tyler to face off against the jury, who decided their fate, and voted Kaycee the winner, 5 to 4.
ET's Brice Sander spoke with the night's big winner after the show, and asked her if the reality of her victory had sunk in yet.
"Not even a little bit," Kaycee said. "I'm super excited, but it hasn't sunk it yet. It barely sunk in that I was even on Big Brother, so it's crazy."
After spending 99 days locked in the Big Brother house, the 30-year-old reality star said she couldn't be happier about getting to go home to her real life.
"I'm so excited to be free. I could not wait. Especially the last couple weeks," she admitted, adding that she really wants to "catch up on life."
"I feel like I've missed so much," she added.
As for how she's going to spend her prize money, Kaycee said she plans to spend most of it on her family, both here and in the Philippines. Her goal is "to make life easier for them, in any way that I can."
While Kaycee took home the grand prize, Tyler walked away $50,000 richer for coming in second. He was also shocked when host Julie Chen later announced that he'd been voted America's Favorite Houseguest by viewers, earning himself an additional $25,000.
The finale's jury deliberations also took the world by surprise when Chris "Swaggy C" Williams got on one knee and popped the question to his showmance girlfriend and former houseguest Bayleigh Dayton!
