Sienna Miller's a Karaoke Queen  1/2/06

Actress Sienna Miller is a karaoke queen - but don't ask her to sing Dolly Parton's hits. The Alfie star insists she doesn't need to be drunk when she's on the microphone, although she often is. 

But Miller recently discovered she should never choose to belt out a Dolly Parton song after showing off her singing skills at Shreveport, Louisiana, hotspot the Rockin' Rodeo. 

She explains, "I decided to do 9 TO 5 and I don't know how Dolly does it... because she doesn't breathe in that song. "I'm karaoke mad. I can do it sober."
