"I was really excited because The Voice called and said they wanted me to perform on the finale, and I obviously can't refuse," Gaga told host Carson Daly following the Dec. 17 performance. "Such an amazing show! And I said I want to know if Christina wants to do it with me!"
The "Beautiful" singer responded, "When I heard she wanted to collaborate, I said of course! She's such an innovative artist and a risk taker. And as a fellow female, I have so much respect for that."
The two ladies were excited to surprise their fans and took to Twitter to announce the special single.
"Happy New Year! Loved performing #DWUW with @LadyGaga so we made a special version just in time for NYE! XoXtina," Aguilera tweeted.
"Happy New Years Twitterverse, I wish you a beautiful and happy 2014, I wanted to start little monsters 2014 with a surprise so…Here's 'Do What U Want feat. Christina Aguilera' STUDIO Version. pink champagne, gold lame, hair, and fearlessness," Gaga tweeted.
The two ladies were rumored to be in a feud around the start of Gaga's career in 2008, but before her Voice performance, the queen of the Little Monsters worked to dispel those rumors on a September appearance of Watch What Happens Live.
"I'm a very big fan of Christina Aguilera," she told Andy Cohen. "From the very beginning of when my career started there was all this controversy about the two of us, and I always felt that it was very unfair to her."
