Who’s your favorite celebrity? Do you think you know more about them than themselves? ABC will be putting celebrities and their fans to the test on their new game show, Big Fan.

The show is based on the “Who Knows… ?” segment from Jimmy Kimmel Live, which pits celebrities against their biggest fan in a trivia challenge.

Hosted by Andy Richter, Big Fan will extend the talk show segment to a half-hour series where one celebrity will compete with three of their biggest fans to see who knows them best.

No word on when the series will premiere.

Read the full announcement below:

ABC has given a series order to “Big Fan.” The half-hour weekly comedic game show will be hosted by Andy Richter. Late-night television host, writer, and producer Jimmy Kimmel teams with Banijay Studios North America to produce. “Big Fan” is based on the hilarious “Who Knows… ?” the celebrity vs. super-fan game segment that originally aired on “Jimmy Kimmel Live.” The segment became a viral video success when pop star Katy Perry went up against one of her biggest fans in this hilarious challenge. Each episode of the half-hour, studio-based game show will feature one celebrity and three of his or her biggest super fans. The super fans will go head-to-head to see who knows more about the episode’s featured celebrity. The succeeding super fan will move on to the final round in an ultimate showdown, celebrity vs. super fan, to see who knows most about the celebrity. If the super fan wins, their prize is a priceless experience with the celebrity they admire most.

“This show is a lot of fun,” said Jimmy Kimmel. He added, “Andy Richter is a great host, and I can’t think of a better way to terrify celebrities.”

“Night after night, ‘Jimmy Kimmel Live’ delivers a slew of great comic bits. There were many to choose from, but “Who Knows… ?” featuring Katy Perry stood out as one that could be expanded into a really unique comedic game show concept that gives fans at home a chance to be part of the experience,” stated David Goldberg, Banijay Group President and Banijay Studios North America CEO. “Thankfully, Jimmy and ABC agree. Collaborating with Jimmy and Andy, two of the funniest people on television, on our first game-show format under the new Banijay Studios North America banner, is very exciting.”

Jimmy Kimmel; David Goldberg, Banijay Group President and Banijay Studios North America CEO; and Caroline Baumgard, chief creative officer, Banijay Studios North America, will serve as executive producers.”
