They sang like angels for their audition on Tuesday's 'American Idol' premiere, but a pair of Memphis twins may sound more like jailbirds by the time the show goes live from Hollywood.

Terrell Brittenum, 28, has been in jail since Jan. 10 on an outstanding warrant for charges related to the illegal purchase of a car in Rockdale County, Ga., east of Atlanta.

He and his brother, Derrell, are accused of using another man's identity to buy a 2005 Dodge Magnum in June.

Derrell was expected to turn himself in on the same charges of forgery, theft by deception and financial identity fraud, The Commercial Appeal newspaper reported.

The brothers auditioned together in September for the hit TV show 'American Idol' and impressed the show's prickly judges to continue to the next round. Segments of the show have already been recorded and will air during the next few weeks.

Fox Broadcasting Co. refused to discuss the Brittenums or their status on the show.

The return of the show Tuesday drew its best-ever season premiere ratings with 35.5 million viewers. It was a 6 percent increase over last year's debut, according to preliminary Nielsen Media Research figures.
