The Sun UK says that Britney Spears new single "Cold As Fire" opens with the lyrics:

"I'm just the girl with the ability to drive a man crazy/ Make him come in my mouth/ Make him my new baby…”

And I guess it can sound like that if that's what you want it to sound like, but breatheheavy.com says the real lyrics are:

"I'm just the girl with the ability to drive a man crazy/ Make him call me mama/ Make him my new baby…"

I'm gonna go out on a limb and suggest you’re not gonna learn anything by trying to interpret Britney Spears lyrics.  She probably did say "come in my mouth".  This retard couldn't interpret a stop light, you think she's gonna write coy references to sex?  She's an idiot.  A talking pegasus could grant her three wishes, and if you asked her about it the next day, she would just say, "a who did what now?"
