He worked with Britney only because of Dr. Luke, and I wanna believe that will never happen again.
Plus he co-wrote Gasoline and Shattered Glass for Britney while co-wrote Just A Fool, Vanity, Glam and Desnúdate for Xtina. He obviously hates Britney and loves Christina.
I watched this video first and thought the guy was counting up from 1 (like "1-2-3!") and that Britney was supposed to hit the switch at "3" but did it at "1" by mistake. The guy also awkwardly laughed after she did it.
