• Anderson Cooper, Savannah Guthrie, Dr. Mehmet Oz and Dr. Sanjay Gupta will guest host "Jeopardy!" this season
  • Mayim Bialik, Katie Couric, Aaron Rodgers and Bill Whitaker were announced as guest hosts in January
  • A donation to a charity of their choice will be made in concurrence with each celebrity guest host's "Jeopardy!" appearance

Several big names will be serving as guest hosts on "Jeopardy!" this season.

Executive producer Mike Richards announced that CNN anchor Anderson Cooper, "Today" co-anchor Savannah Guthrie, "The Doctor Oz Show” host Dr. Mehmet Oz and CNN's chief medical correspondent Dr. Sanjay Gupta will all be part of the new roster of guest hosts for the trivia game show in the wake of Alex Trebek's death last year.

The celebrities will be hosting "Jeopardy!" to raise funds for their charities of choice, Entertainment Tonight reported. During the weeks they take their turn hosting the quiz show, the cumulative winnings of the contestants will be donated to the guest host's selected charitable organizations.

"We look forward to each guest host bringing their unique abilities to the show and to our contestants winning a lot of money that we can match for charity," Richards said in a statement released Tuesday.

The latest group of celebrity hosts join previously announced
"Jeopardy!" guest hosts Katie Couric, Green Bay Packers quarterback Aaron Rodgers, “60 Minutes” correspondent Bill Whitaker and neuroscientist and actress Mayim Bialik. They were announced as upcoming guest trivia masters back in January.

The string of guest hosts will take the reins from Ken Jennings, who took over "Jeopardy!" following longtime host Trebek's death on Nov. 8. He recently signed on as the show's consulting producer. He had been paying tribute to Trebek's legacy during sign off, saying, "Thank you for watching, and thank you Alex."

His sign-off received mixed responses from the Twitter users, with some saying they were touched every time they hear it, while others feel it no longer sounds sincere because they hear it from him all the time.

"Every single time @KenJennings thanks Alex at the end of @Jeopardy, I get all choked up. I hope he never stops," tweeted "Save the Cat" author Jessica Brody.

"Same!!! I always get a lump in my throat. I think Ken is a perfect fit, I respect and appreciate him. It’s a good fit! He’s got my blessing!" a Twitter user agreed.

But another wrote, "I wish he would stop it. The first week, it felt sincere. After so many times, starts to feel insincere and gross. We are all grieving and hurting. It is painful. Ripping off that band-aid at the end of every show is morbid. Just stop. Please."

Jennings explained that the sign-off was suggested by executive producer Richards, and he was happy with it because "there wouldn't be a show without Alex."
