There has long been talk of an ongoing feud between Christina Aguilera and Lady Gaga. However, whatever beef the two had for each other, if any, is apparently long gone after their performance on The Voice last night.

For the very first time on Tuesday, December 17, the two powerhouse singers took to the stage together to perform Gaga’s hit Do What U Want. When the producers of The Voice called Gaga and asked her to perform during the season five finale, Gaga said she couldn’t turn the opportunity down, but wanted Aguilera to join her on stage. “I was really excited because The Voice called and wanted me to perform on the finale and I obviously can’t refuse,” said Gaga, 27. “It’s such an amazing show and I said, ‘I’ll do it, but I want to know if Christina will do it with me.”

When the producers confronted Aguilera about the possible collaboration, Aguilera said she instantly said yes, and that she had been dying to meet her. “This is the first time we’ve ever met and I have to say, when I heard she wanted to collaborate I said, ‘Of course! Lady Gaga!’ I’ve been waiting to meet her. She’s such an innovative artist and a risk taker and as a fellow female, I have so much respect for that,” Aguilera said. “She’s the most down to earth real person that I’ve ever met in this business. Female to female in this industry, it’s really hard to find that kind of a person. I love you girl, and you deserve everything that you’ve earned.”

She is such a powerhouse vocalist and I was honored to join the stage with @ladygaga tonight on #TheVoice! xo

During an interview in September, Gaga shared her mutual feelings for Aguilera. “I’m a very big fan of Christina Aguilera,” Gaga said during an interview on Bravo’s Watch What Happens Live. “From the very beginning of when my career started, there was all this controversy about the two of us. I always felt that it was very unfair. Christina is an incredible vocalist and an incredible artist,” she continued.

“From me to her, I’m so sorry for anything that anyone ever said to her because of my existence. And I hope that she never felt any way about it, because when I was 15, I was singing ‘I Turn to You’ at the top of my lungs trying to hit all her notes. So she was an inspiration to me to have a wider vocal range, and I just think it’s all total nonsense the way that they do that.”
