I dunno...she's fairly hawt.
The only thing I don't like about Krall is a number of years ago I attended her concert. I swear the whole set was maybe about 40 minutes long. Tix were roughly $60 CDN a pop at the time. We felt extremely ripped off. But we were sixth row on the floor from the stage and she did look hawt.
Great way to treat your fans Costello/Krall family.
