Britney looks like she's having fun making the video! I wish y'all would say she doesn't want to do it. She clearly enjoys making the videos and having fun, she's just very shy and likes for people to respect her privacy.
So, from Jeff's tweets, guessing the first snippet is one of the verses and the second is the pre-chorus. Awesome, probably means we haven't heard the chorus and hook yet, they better be big.
It's so nice when everything points in the right direction! Sonically apt, an enthusiastic Britney, a decent video with Iggy at the helm... I'm much more optimistic than I expected to be. If we've come this far why not get our hopes up for a performance? If the rumors are true Iggy certainly wants it.
