Gaga and Aguilera official team up
Lady Gaga has debuted the official recording of her debut with Christina Aguilera on her YouTube channel.
The pair had teamed up in the final episode of The Voice in the US to perform Gaga's hit Do What U Want, originally recorded with R Kelly, and have now gone into the studio to make it an official hit, according to Digital Spy.
Applause singer Gaga decided to duet with Voice coach Christina after publicly apologising to her about comparisons between them which had led to their fans being divided.
Lady Gaga said: "All I know is that people were talking about Christina Aguilera and Lady Gaga.
"I just think it's very unfair for anybody to pit another woman against another woman. Especially in the space of music when we are all just trying to be taken seriously.
"From me to her, I'm so sorry for anything anyone ever said to her because of my existence."
Do What U Want comes from Gaga's third album, ARTPOP, which reached number one in both the UK and US when it was released in November.
