The delusion in this thread is too much
Both are flops at the moment & this fighting is so trivial. But anyway.
If Britney stans are happy to talk about S&S why are Xtina stans not allowed to bring up MLJ or FTM? Honestly...
Christina currently has a #1 hit on iTunes, a DUET not a feature. If a Great Big World was the reson behind it's success the version without Xtina wouldn't have bombed hard.
Christina is also currently on the hit show, The Voice & is sizing up for a comeback era.
Britneys latest single, Perfume is bombing.
So looking at RIGHT NOW, Christina is bigger.
