When is the next show for American Idol?

I do not have real-time information or access to the latest updates, so I cannot provide you with the exact date for the next show. The information I can provide is as follows:

According to the most up-to-date information available to me, which was last updated in late 2022, the next season of American Idol, which would be Season 21, is scheduled to premiere in spring 2023. However, please note that this information could be outdated, and the actual premiere date may have changed.

To stay up to date with the latest information on the next show for American Idol, including the specific premiere date, I recommend checking the official website or social media pages of American Idol.
