R. Kelly, out! Xtina, in! Lady Gaga and Christina Aguilera have teamed up for a new version of Mother Monster's 'ARTPOP' hit 'Do What U Want.' It's the Xtina remix!

Or we can call it 'Deux What U Want,' since it's another (or second) version of the song, the Rick Ross remix version, which you can listen to here, notwithstanding.

The original, recently inducted into the Pop Clash Hall of Fame, features R. Kelly as Gaga's sultry duet partner.

However, Gaga performed it with Xtina on the Season 5 finale of 'The Voice' earlier this month. The blonde divas, who previously beefed in the press, sipped champagne and vocally dueled while wearing matching white outfits on the reality show.

The live version was hotter than lava, so we're not shocked that they are making a commercial version of the song available. Just Jared reports that it is a studio version. So far, no word from Gaga or Xtina about the version.

Unless, perhaps, the tweet and photo Xtina posted on Dec. 24 aka Christmas Eve was the special something she spoke of? Could be!

The track will be available tomorrow, Jan.1, as per Amazon. It's a New Year's Day present.
