The 16th season of CBS's reality show 'Big Brother' is coming to an end on Wednesday, and only three people are left inside the house.

The final winner of the 'Big Brother' Season 16, who will be $500,000 richer by the end of finale night, is among the 30-year-old undercover cop Derrick Levasseur, 23-year-old former soccer player Cody Calafiore and 22-year-old photographer Victoria Rafaeli.

Each of the final three contestants has shown their strengths and weaknesses throughout the show, and it would be difficult to predict who will emerge victorious among the three.

There are reports saying that Levasseur and Calafiore are ahead of the game, since they each won a round of HOH competition.

Spoilers from the CBS live feed reveals that the contestants have already completed the HOH rounds. The first round of HOH was reported to be an endurance test, where the final three contestants were seen hanging from hang-gliders in the 'Big Brother' house's backyard. Rafaeli was the first to let go, while Calafiore and Levasseur had a discussion on which one of them should win the round. Levasseur decided to let go, leaving Calafiore as the round's winner.

The second round of HOH was held on Saturday, where Levasseur and Rafaeli competed with each other. The nature of the round is unknown, since the live feeds were mostly down during that day. It was reported, however, that Levasseur won over Rafaeli in the second round.

The results of the first two HOH rounds mean that Levasseur and Calafiore will be going against each other for the third round. The winner of the final HOH round will decide who they are taking with them as the final two. This means that at either Levasseur or Calafiore is guaranteed a final top two spot.

Meanwhile, the show's host, Julie Chen, reveled in an interview who she thinks will emerge as the Season 16 winner.

"Any way you slice it, Derrick's going home a half million dollars richer. I just don't see him losing to either Cody or Victoria. I don't see him not sitting in the Final 2, I just don't. Cody is not going to stab his mentor in the back, it's just not in his nature, and if it were ever Victoria making that decision, she loves that guy. She has no bond or connection to Cody. Derrick has a big check coming his way, my prediction," Chen told The Hollywood Reporter.

The 'Big Brother' Season 16 finale airs at 9:30 pm PT/ET Wednesday on CBS.
