Australian rockers Crowded House are keen to work with Britney Spears because of her "bad-ass" reputation. The band collaborated with U.S. country stars Dixie Chicks on track Silent House earlier this year (07), and are keen to expand their musical repertoire. Frontman Neil Finn refuses to rule out any pop stars for forthcoming collaborations - but hints he would like to work with troubled singer Spears. He says, "As for future collaborations after the Dixie Chicks, I wouldn't pre-empt anyone. "Britney's hitting the tiles - and she's a lot more interesting now she's become bad-ass."
