So What's Up With the Prosthetic Arm Lady Gaga Has Been Using in Her Promo Photos?

(Facebook)Lady Gaga has yet to officially tease any snippets of her upcoming album, ARTPOP, but she has been offering major thematic hints with her promo material. In pictures posted to the performer's Facebook, she sports surprisingly natural-looking makeup, no shirt, ridiculous shoes, and a funky prosthetic arm.

So... what's that about?

In a Facebook post late Thursday night, Gaga hinted that it had something to do about how she feels having to wait to release the new tunes. 

Yes: "IF I HAD TO GO ANOTHER MONTH WITHOUT PLAYING THE NEW MUSIC I THINK ID CHEW MY ARM OFF." 

She's so deep, that Mother Monster.

Thankfully, Gaga will retain both arms, as her new single "Applause" is due for release on August 19, along with a video shot by Gaga's artsy pals Inez & Vinoodh.
