I think she was spot on.
She had the toughest decision to make since Hannah deserves to be in the live shows more than all the boys, more than Girland or Bad Lashes and more than Rachel and Daniel, yet unfortunately the other 3 girls were just too strong. I would have liked Hannah to make the live shows because her version of Piece of My Heart was outstanding, but Diana's Hallelujah is probably my fave X factor performance ever, Laura is outstanding, and as much as I dislike Alexandra as a person (With her single bed between two and her Blackberry?) her voice is outstanding. I agree with above post about her being a Maria Lawson style contestant rather than Leona. I think Diana with the right songs could easily reach Leona heights, she has a great unique voice in the competition and I think Cheryl will "do a Dannii" and have her two acts in the final 2, with Diana V Laura. (hopefully with Diana winning)
