Britney Spears - Till the world ends (remix version)

A brand new remix for her new single "Till the world ends". This time, featuring 2 big stars Nicki Minaj and Ke$ha. "Till the world ends" is great itself, with Nicki's rap and Ke$ha's electro-like vocal, it even gets hotter. Personally, I prefer this remix, now it's all your to enjoy. Grab it now on itunes!
