What else is she supposed to do, willingly let her career die with little to no exposure? This is a good move because people will remember how good she is especially compared to the current standard of X Factor contestants.
Hardly! She criticised the label for trying to make her do a covers album, but she has always spoken positively of Simon and they have both publicly spoke positively about each other since she left.
Plus she is going to back to the show that's viewers changed her life, that gave her a career, she would be a fool to turn her back on them.
When did she slag off Simon or the show? I always took her comments as being directed at someone she had to work with at the record label - it's not like she would've worked with Simon closely on her music.
