Word on the street is that Christina Aguilera has teamed up with Australian rapper Iggy Azalea for her new "killer" single.
According to AceShowbiz, "With there being some speculation about Christina working with Azalea for quite some time, a source now confirms the duo has been hitting the recording booth together."
The site then adds, "the track is rumored to be recorded for Christina's next studio installment, and the pop singer is said to be excited at the prospect of releasing the track as a single. She is said to be hard at work on her new album, shortly before the premier of the fifth season of The Voice, where she's a judge/mentor on the panel to contestants.
The source also claims there's a lot of pressure for Christina to deliver an album that sells like her previous releases, blowing competition out of the water.
This might be fake because I couldn't find the article on AceShowbiz.
