You can get that ad for a (very expensive) song on the upcoming finale of "American Idol."

A 30-second spot on this season's "Idol" swan song will cost a stratospheric $1.3 million, according to a report in Advertising Age magazine.

While that's not quite Super Bowl numbers ($2.5 million for a 30-second ad for this past Super Bowl), it's more than was charged for last season's "Idol" finale ($1.19 million for a 30-second spot).

That show, which aired in May '05, was also in heavy demand and, in fact, came thisclose to equaling the cost of a 30-second ad on the much-ballyhooed series finale of "Everybody Loves Raymond" ($1.22 million).

And the cost-per-spot for this season's "Idol" finale isn't that far off from the record holder for a series finale. That distinction belongs to "Friends," which raked in $2 million-per-spot for its May 2004 finale, according to Ad Age.

As far as "Idol" is concerned, advertisers are willing to shell out the big bucks, and for good reason.

Last year's "Idol" finale, which crowned Carrie Underwood as the champ, averaged 29 million viewers — a number likely to be equaled or topped in this season's live finale, airing May 24 from Hollywood, virtually guaranteeing advertisers a big bang for their megabucks.

This season of "Idol," in fact, has been the most popular in the show's history, regularly averaging 30 million viewers each week on FOX as TV's top-rated show.

"Idol" judges Simon Cowell and Paula Abdul recently inked multiyear deals to remain on the show, while "Idol" host Ryan Seacrest has spun off his own little empire — including co-hosting ABC's "New Year's Rockin' Eve" with Dick Clark and spearheading E!'s news and red-carpet coverage.
