Kelly probably won't get #1. The Wanted also released a single and they're already #7 compared to Kelly's #12 - Which is still amazing!
Unfortunately, The X-Factor promo might not get the #1 either since Professor Green is also performing that night, and his single is released the next day.
I hope Kelly either overtakes The Wanted or can hold off Professor Green, but I doubt it. Top 5 would still be amazing for a "flop" single, and I'm sure it'll be stable.
