She seems to have a little momentum now and SOY didn't do good because the song shouldn't have been a single and media trashed her she's on track for a hit and is obvious Simon will have her on XF he said he'd like to work with her again.
Simon will definitely have her perform on The X Factor this year, he wouldn't want to miss out on the headlines and media circus surrounding her. Although, I do think he is rooting for her and wants to give her the platform for success as well.
