Who is the sexiest female vocalist?

I have been into the high-end...esp. with Jazz and female vocals since 1969. Believe it's best to share several and, hopefully, you will have a chance to try some...and form your own likes.
1. Helen Merrill..esp. "You'd be so nice to come home to"
2. Rosanne Cash...esp. "Somewhere in the Stars".
3. Julia Fordham...esp. Her 1st 3 CD's
4. Sarah Vaughn...almost anything.
5. Billie Holiday..."Songs for Distingue Lovers".
6. Shirley Horn...the last 3 or 4 releases.
And,..Rosie Clooney, Ms. Krall, Ella F., Valerie Carter, most any female doing the songs of Cole Porter or Johnny Mercer...and others..see the above posts...or the ones to follow.
As a closing,,,..I think that female vocals and Jazz lead where you want to go.
P.S. ..did I mention June Christy?

I saw Bonnie Raitt last summer at Jones Beach, Long Island, N.Y.. The sun setting over the ocean behind the stage, singing "I Can't Make You Love Me", I was hooked.

Susannah McCorkle. Unfortunately, we just lost her.

Nico. Call me strange but she does it for me. Also Chan Marshall from 'cat power.' definitely call me strange. WAIT! What was I thinking: Milla Jovovich! from 'The Divine Comedy' - gawd!

Nico, 'cause she's dead.
