Mayim Bialik wore a Jewish star while she filmed all of the "Jeopardy!" episodes that she co-hosted. 

Bialik was announced as one of the new permanent hosts of the game show Wednesday. The "Big Bang Theory" star and executive producer Mike Richards will take over the role previously held by Alex Trebek, who died last November. 

"Here’s a fun secret: I wore a Jewish star in every episode of ‘Jeopardy!’ that I guest hosted," Bialik told the Jewish Journal. "Sometimes a pin, sometimes a ring and most often, one of two ‘hidden’ Mogen Dovids. One of my outfits featured earrings from The City of David in Jerusalem, which were unearthed in a dig in recent years.

"I find ways to maintain my sense of ‘Jewishness’ wherever I go," she added. "And it’s especially important to me to do that on such a public stage."
