Fox will wring an extra minute of fame out of American Idol with American Idol in Las Vegas, a two-hour special airing late next month.

The special will feature a concert with all 30 of the pop star wannabes who made the final cut in the summer's biggest hit (anyone remember EJay Day or a Jim Verraros?). 

The concert, taped before a live audience at the MGM Grand Hotel in Las Vegas, will air Sept. 23 (8-10 p.m.) 

The highlight will be a performance by whoever ends up winning American Idol, which ends its summer run next Wednesday with a two-hour special (8-10 p.m.) in which the lucky victor will be announced. 

Idol co-hosts Ryan Seacrest and Brian Dunkleman will appear on the special. 

It's not yet known if Idol judges Simon Cowell, Paula Abdul and Randy Jackson will participate in the Vegas special. 

On tonight's special one-hour edition of Idol, one of the three remaining contestants -- Justin Guarini, Kelly Clarkson and Nikki McKibbin -- will get the boot, leaving only two people for next week's finale. 

Since its debut, Idol has engaged America as 10 finalists have battled to win the ultimate prize: A recording contract with RCA, which will release a single complete with heavy publicity and promotion. 

Last week, Idol drew over 15 million viewers, a hefty number for a summer series. The show will return next January in its second incarnation.
