Mayim Bialik and Ken Jennings will host "Jeopardy!" for the rest of the year

Mayim Bialik and Ken Jennings will host "Jeopardy!" through the rest of the year, the popular game show announced Thursday. The "Big Bang Theory" actress and the former champion were selected after Mike Richards stepped down when inappropriate comments he made resurfaced.

Bialik, 45, will host episodes from September 20 to November 5. After that, she'll split hosting duties with Jennings, 47.

Bialik rose to fame during her time on the hit show "Big Bang Theory." She was already tapped to be the next host for digital and special "Jeopardy!" episodes and tournaments but will now take a turn hosting primetime episodes before she shares the job with Jennings.
