There is a BIG difference between saying "we have a surprise" and hint it could be Britney and using her lyrics/herself in marketing campaigns AGAIN when it's most likely she won't even show up. That's what's absurd. If you can't understand that, then you better go back to primary school.
What are you on about? I didn't disagree with you, I explained why they do it.
That Britney gif is just hilarious
