What feud?!

Lady Gaga and Christina Aguilera put their differences aside to perform a duet to "Do What U Want" on The Voice season finale last night, and we love how the divas wore matching gold outfits as they belted out Mother Monster's latest hit!

    "I was really excited because The Voice called and said they wanted me to perform on the finale, and I obviously can't refuse. Such an amazing show! And I said 'I want to know if Christina wants to do it with me'," the eccentric singer explained to host Carson Daly.


Xtina was flattered by the invitation, and didn't hold back on her praise for Gagaloo!

    "This is the first time we've ever met. 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. And I just have to say guys, she's the most down-to-earth real person I've met. So I love you girl, and you deserve everything you've earned," the singing coach gushed.


Is hell freezing over?! Next thing we know, Mariah and J.Lo are going to bury the hatchet!
