sexiest sounding female vocalists?

ok what's your thoughts regarding the sexiest sounding female vocalist out there? Just discovered Diana Krall guess the picture on the cover of the look of love may have contributed to my feelings somewhat also.
Gosh! I've fallen in love so many times? Here are three voices I've been smitten by...
1. Babel Gilberto
2. Morgana King
3. Carmen Lundy singing:All Day, All Night
I need your body to feel my body,
I want your body close to mine,
A little lovin'
Don't hurt nobody
I want your body next to mine.
All day, all night,
All day, all night,
Make love all day,
Make love all night...
