With reports already out that Katie Couric and Aaron Rodgers will be acting as Jeopardy! hosts as the show tackles the daunting task of replacing the late Alex Trebek, the show has officially announced its next roster of guest hosts, but this time, it will have a charitable twist. In a tweet from the official Jeopardy! account 60 Minutes’ Bill Whitaker and The Big Bang Theory‘s Mayim Bialik have been confirmed as guest hosts along with Couric and Rodgers. “As a part of each guest host’s appearance, a donation will be made to a charity of their choice,” the show also announced.
