Watch Gwen Stefani Lose a Game of Gwen Stefani Trivia

Gwen Stefani is one of our 25 Greatest Frontwomen of All Time, but that doesn’t mean she’s the greatest at trivia— at least, not when the topic is herself. Last night on Jimmy Kimmel, Gwen played a game of “Who Knows Gwen Stefani?” against a Stefani superfan named Diana. Spoiler alert: She lost.

Diana’s knowledge of Stefani was truly impressive to behold. She knew what Gwen’s first job was, where her dad worked when she was a kid, and the name of the first song she ever wrote. Diana has a vanity license plate that reads “NO DOUBT,” so if you ever see it on the road, you’ll know who’s behind the wheel.

Watch the iconic frontwoman lose hard in the video below.
