'Skyscraper' beauty Demi Lovato has taken to her official Twitter page to tell fans that this year's new season of 'X Factor USA' has the potential to be the very best.

Lovato recently signed a contract to appear on the popular TV vocal talent show for a second series and has confessed to her followers that the level of talent this year's auditionees are bringing to the table is unbelievable:

"Dare I say it...... This season is so much better this year already and it hasn't even AIRED yet!!!!! Just wait... And the TALENT?!?!?? This years talent is INSANE... Idk HOW you guys are only gonna be able to pick 1 winner!!!!!!"

She then returned to the social networking site a little later and added: "These past two days have been so intense-was LITERALLY at the edge of my seat... Wait till you guys see the changes to the show.#XFACTORUSA."

Lovato, meanwhile, is due to release her very first book in November called 'Staying Strong' and confirmed that it will include inspirational quotes, goals and motivational paragraphs to help encourage readers with their personal journeys.
