"American Idol" is close to landing KATY PERRY as its main judge . . . and the official announcement could come tomorrow. If that falls through, WILLIAM HUNG is "willing to consider" stepping in.
Perry may be the only judge they announce, because the producers haven't even decided who they want for the other two spots.
The show is on a tight budget this time around, so after making a big splash with Katy, the other two spots will probably go to cheaper options . . . like a songwriter and a music producer.
RYAN SEACREST is still in the running to be the host, which put quite a dent into the show's budget.
An IDOL blast from the past, WILLIAM HUNG recently said he's "willing to consider" being a judge, guest judge or performer on the new "Idol". Check out Hung's memorable IDOL audition below.
