Pop megastar Britney Spears has told her fans to prepare for the upcoming video that will accompany her collaboration with Will.i.Am, which is called 'Scream and Shout'.

She took to her official Twitter page last night (November 8) and teased that it's going to be a big release for her:

"Editing the #ScreamAndShoutVideo. U guys are gonna die when u see this..."

Spears also finally unveiled her new commercial for the fragrance 'Fantasy Twist' this week, and the clip shows her dressed in several different eye-catching outfits while walking the halls of a decadent hotel.

UK boyband One Direction were guests on X Factor USA yesterday and she returned to the social networking site to tell her followers that she can barely hear from all the girls screaming during their performance:

"My ears are still ringing from all the screaming for @OneDirection on @TheXFactorUSA tonight, haha. What cuties!"
