The guest host roster for "Jeopardy!" is expanding even further.

Anderson Cooper, Savannah Guthrie, Dr. Mehmet Oz and Dr. Sanjay Gupta were announced among the guests who will follow Ken Jennings in the host role.

The appearances also go for a good cause, with the show saying on its website, "As a part of each guest host's appearance, a donation will be made to a charity of their choice. The amount donated will equal the cumulative winnings of the contestants that compete during the weeks they serve as guest host."

The new crop of guests join a star-studded list that includes Packers quarterback Aaron Rodgers, journalist Katie Couric, actress Mayim Bialik and "60 Minutes" correspondent Bill Whitaker.

That list isn't finished yet -- more guest hosts are due to be announced in the future.
