Celebrity Clash!

"Welcome to Celebrity Clash!" the host shouts

"In Celebrity Clash, our selected participants compete to win the secret prize. But to win it, each team will have to win the most challenges at the end of the competition day, scoring points for each challenge achieved. The losers will receive a punishment for each challenge failed. Also, each team will have the posibility to make only one prank just to one of the loser teams, and these pranks will give them extra points, but if they make more than just one or to the team that they didn't choose to make the prank, they will receive a extra humiliating punishment. So, it's time to meet the teams:

TEAM RED: Katy Perry, Emma Watson, Scarlett Johansson, Danielle Panabaker, Keira Knightley, Olivia Munn and Megan Fox.

TEAM BLUE: Taylor Swift, Anne Hathaway, Charlotte McKinney, Jennifer Aniston, Alexandra Daddario, Ariana Grande and Emilia Clarke.

TEAM YELLOW: Lady Gaga, Jessica Alba, Sophie Turner, Jennifer Lawrence, Natalie Dormer, Victoria Justice, Kat Dennings and Kristen Stewart.

"So, time to see the first challenge..."
