The Dixie Chicks got a decidedly cool reception at last night's Academy of Country Music Awards. Not only did the embattled country trio go home empty-handed (they were up for three awards), but the George Bush-lovin audience booed the mere mention of their name. At one point during the CBS ceremony, Vince Gill urged the crowd to "stop it," adding, "You know who gets blessed when you forgive? You." Meanwhile, the night's big winners included Alan Jackson (album of the year for Drive), Toby Keith (entertainer of the year) and Brooks & Dunn (best vocal duo).
