Forbes' ranking of the world's most powerful celebs, the Celebrity 100 list, doesn't come out until Wednesday, but today we can tell you the notable names who won't be on the list.

PICS: Candid Celeb Sightings

Adele, Taylor Lautner, Brad Pitt, Johnny Depp and Britney Spears were among those left out of the prestigious lineup, but the magazine explains in a new article that their absence is only due to the annual updating of the list.

While Brad Pitt has ranked on the list for each of the last nine years, working on World War Z caused him to drop from the spotlight between June 2012 and June 2013 -- the time period in which the Celebrity 100 based earnings and fame for this year's list.

As for Adele, despite winning an Oscar for Skyfall (the theme for the latest Bond movie) the singer failed to headline a major global tour, making it difficult to put her in the running.

Johnny Depp's big 2012 project Dark Shadows failed to draw big attention at the box office, but next year could prove better for the Golden Globe winner, as The Lone Ranger opens July 3.

Similar to Adele, Britney Spears' The X Factor check wasn't enough to make the list without a big tour, and Twilight star Taylor Lautner has struggled to build a career in the wake of the popular vampire series.
