Christina Aguilera is reportedly set to release a song produced by Kanye West "this week", according to a source.
The 'Beautiful' hitmaker is said to be planning on dropping the "tribal-like" track produced by the 40-year-old rapper "this week"
A source told The New York Post's PageSix Column that the song "is produced by Kanye [West] and that "It's very tribal-like, with heavy drum samples . . ."
The insider also teased that her first single from her forthcoming record, thought to be called 'Liberation', will feature another "big" artist and her album is a complete new direction for Christina who has given her image an overhaul with the help of a new manager.
They added that "the first proper single from the album will be a big duet, but her team isn't ready to announce the other singer -- yet.
"Christina has changed her look, her management has got her great new artists and consultants to work with, she's in a great place."
The 37-year-old star teased the record's title during a concert in Azerbaijan last weekend.
During a short interlude, a video was shown which seemed to tease the star's upcoming eighth studio album
A fan recording of the video was posted on Twitter by fan account Xtina Daily, and shows a series of shots of the megastar whilst her voice lists a series of words beginning with "ex".
Christina says in the video: "Ex. Xtina. Exhale. Explore. Express. Experiment. Exploit. Exclusive. Exist. Expire. My existence has no expiration. This is my liberation. This is our liberation. Be liberated with me. It's time for liberation. As one, a liberated nation."
The video concludes with the words "Xtina, liberation" repeated several times.
'Liberation' will be Christina's first album in six years, with her last studio venture being 2012's 'Lotus'.
