Christina Aguilera has recorded a song about oral sex, but has vowed never to release it.

The 'Dirrty' singer revealed she laid down the X-rated track called 'F*** You, Suck You' during one drunken night in the recording studio.

And despite record producer Linda Perry's pleas, Christina says the only people who will get to hear the racy lyrics are her close friends.

Speaking at the Grammy Awards, she said: "We recorded it one night over whiskey in the studio.

"It's completely breathy. Linda wanted to put it out under someone else's name.

"But I play it when I have my friends over when we've had one too many and start rolling around the floor with each other."

Christina, 26, also confessed her own music is a turn-off when she is having sex with husband Jordan Bratman.

Is it just me, or does it seem like Christina will say anything so she can seem a lil scandalous? She's just one crotch shot away from making headlines. Don't do it gurl.
