Madonna will indeed appear — and perform — on the April 9 “Tonight Show Starring Jimmy Fallon.”

When your career has been as iconic as that of Madonna, you cultivate a passionate fanbase. When you cultivate a passionate fanbase, you can bank on them working vigorously to stay apprised of your endeavors.

Neither Madonna nor NBC, therefore, had a prayer of keeping her planned “The Tonight Show” visit under wraps.

Earlier this week, Madonna fans located her name on a tentative NBC episode guide. That guide, which identified a handful of visitors for upcoming “Tonight Show” episodes, revealed that Madonna would appear as an interview and musical guest on the April 9 edition of its Jimmy Fallon-hosted talk show.

Issued Thursday evening, a revised, more authoritative “Tonight Show” lineup shares the same story. Madonna is the lead interview guest and confirmed musical act for the April 9 “Tonight Show.” Nikolaj Coster-Waldau will also appear on the episode.

Other upcoming “Tonight Show” guests include Louis CK, Sophia Bush, Julia Louis-Dreyfus, Scott Eastwood, Kevin James and Vanessa Hudgens.
