Sultry singer Christina Aguilera and Linda Perry recorded a saucy track “Fuck You, Suck You” while they were recording her last album Back To Basics, but Chris refused to add it to the project-because it’s to “Dirty.”

“We recorded it one night over whisky at the studio… I play it when I have my dancer friends over, when we’ve had one too many and start rolling around on the floor with each other.”
