0 Lady Gaga and Christina Aguilera bring glitter and girl power to 'The Voice' finale. And it's awesome situation.

Last night's finale of The Voice featured a rare moment of pop diva bipartisanship: Lady Gaga and Christina Aguilera unleashed powerhouse vocals (and gold lame dresses up the wazoo) for a rousing duet rendition of the former’s current single, “Do What U Want.” The result was awesome, a Brave and the Bold style pairing of superheroes that also doubled as a Golden Girls-cum-Solid Gold tribute act.

As far as pop titan team-ups go, this was a pretty grand performance. But if you're a keen (or at least, somewhat obsessive) observer of pop culture, you probably appreciated it for another reason. The hand-holding belt-a-thon featured two singers coming off dicey professional years and rumors of a feud; paired with Gaga's song, which compares the patriarchal music industry's build-em-up-tear-em-down sadism to a form of misogyny, it was also a "sisters are doing it for themselves" moment of solidarity.

0 Lady Gaga Goes Full Frontal Nude in Bizarre Video

Lady Gaga has teamed with Serbian performance artist Marina Abramovic for a bizarre tutorial/testimonial video in which the singer chants, stands in a river, walks blindly in a field and spoons a giant crystal. It should be pointed out that in a good chunk of the clip's two-plus minutes, she is completely naked. The video is centered on the artists's "Abramovic Method" of exercise, which her website says will "heighten the participants’ awareness of their physical and mental experience in the present moment." The video begins with Gaga, wearing all-white, laying flat on a wooden floor and begins to sing "a." It then segues to the singer standing in a shallow river, wearing a jumpsuit and her eyes covered in a horn mask. After that, it's naked Gaga time, with the singer alternately walking in grass, bent over in a yoga pose and doing various things with a large crystal-looking rock. In one part of the video, Gaga and Abramovic sit with their backs facing each other.
