Dead Ex by Harley Jane Kozak

If you have read Dating Dead Men, you will know that Wollie Shelley has a career as a serial dater, and in Hollywood that can mean many things, but in Wollie's instance, it is a real job. And it gets her tangled up in a murder that points to her best friend Joey as the suspect.
