Heads Up: Clay on ET, Insider Tonight

After today's formal confirmation of Clay's scheduled appearance for tomorrow's American Idol finale, both Entertainment Tonight and The Insider will have a top story on Clay's return to American Idol.

According to ET teasers airing today across the nation, ET will tell you "What you don't know about Clay's secret Idol comeback" on tonight's show.

Although ET and The Insider normally come on after the supper hour news, please check your local listings. You might also want to keep an eye on CNN Headline News' Showbiz Tonight and the E! News channel (the one that started all the pandemonium yesterday :) ).

Kind of offtopic, but then again not... here's a transcript of yesterday's ET which also had a headline story on Clay. We posted a cool graphic from that show here.

But not every "Idol" runner-up has shared Guarini's fate. At least one of them - Clay Aiken, 27, second-place finisher in the second "American Idol" in May 2003 - has eclipsed that year's winner, Ruben Studdard, 27, in CD sales and concert receipts.

In fact, Aiken is second only to Clarkson in overall success since appearing on "American Idol." While she leads him in CD sales, Aiken tops Clarkson in concert-ticket receipts - $28 million to $25 million.

Music-industry experts note that recording stars earn more money from concerts than from CDs. That has been especially true of Aiken and Clarkson, experts say, since they are the only two "Idol" stars to emerge so far as bona-fide concert headliners
