name of singer

who was the singer who sang AT LAST in the movie MY MOM'S NEW BOYFRIEND?

Probably Etta James.

Eva Cassidy

I couldn't find a soundtrack for this movie, but I found a bunch of artists that sing a song named "At Last":

Christina Aguilera
Ella Fitzgerald
Cindy Lauper
Norah Jones
Jason Mraz
Celine Dion
Kelly Clarkson

Ah yes, and if you rented this movie, own the movie, or watched it online, remember that at the end of each movie in the credits the artist and song name are stated so you should check the credits for the artist. :]

In this particular movie it is Eva Cassidy I'm sure of it

I have checked the credits ( rented the movie twice, second time just to recheck the credits) and not listed. I have listened to Eva Cassidy and not her, the voice does not belong to anyone listed in these answers. Thank's all, for your answers. Still a mystery.

I'm not sure if this 's gonna make you happy ...
These singers all did the song you're looking for :

Brenda Lee
Caterina Valente
Doris Day
Joni Mitchell
Julia DeMato (this is from American Idol , Season 2)
Petula Clark
Phoebe Snow
Randy Crawford

You should write down all the songs in the credits, perhaps the name of the song is different than what you think it is. Then you should listen to all the songs and see if any of them are the song you're looking for.
