Ohhhh Maaaaa Gheeerrrdd, Usher has been pictured charging his mobile phone using a woman's vagina. Now, we know that it SUCKS when your phone runs out of juice, but… REALLY?

The genital-based phone-charging took place at Art Basel in Miami, an art show for "modern and contemporary works, as well as pieces by newly emerging stars."

One such newly emerging star included in the show is a naked woman who has a battery pack inserted inside her vagina. Because #ART.

Attending the exhibit, Usher reportedly paid $20 in exchange for 10 minutes of charge time. Pretty sure most mobile phone stores charge for free, but whatever floats your boat.

Sorry - are you iPhone 6 compatible?

According to TMZ, "The woman wanted to show how humans have become dependent on technology and she felt a super-charged vagina would help make her point." Sure.

TBH, Usher looks fairly confused by the whole thing and more concerned about whether she had the correct cable than the fact she was totally nude and sat in an art gallery charging electrical devices.

Either that or he was just wondering why Sia had decided to go down the performance art route when Chandelier was such a big hit.
