The newly brunette Lady Gaga threw an important event today, livestreaming her fragrance launch for Fame so all her little monsters could be there with her.

Oh, yeah: She also got a new tattoo on the back of her head—in front of everyone.

"i've arrived to the Guggenheim! live stream of FAME launch event begins in 15 minutes exclusively at http://littlemonsters.com/famelaunch ," she tweeted earlier today.

Arriving to the Guggenheim Museum in a black convertible, Gaga rocked Kwiat jewels and a black lace Prabal Gurung gown, which left little to the imagination (especially on the backside), but that's kinda her style so it wasn't too shocking.

The most shocking thing? During the flashy event, the pop superstar sat in front of an agog crowd as a tattoo artist inked her newly shaved head.

Gaga got a tattoo of a Renaissance-era cherub, which is supposed to be an homage to the singer's Italian heritage.

At one point, she mounted a performance-art piece in which she "slept" inside a futuristic vestibule located in the center of the museum's famous spiral ramp while partygoers watched.

Gaga later shared the inspiration behind her fragrance, and it has nothing to do with fame and everything to do with sex.

"I wanted it to be very sexy," she told Access Hollywood. "And, I also wanted it to be a little bit slutty. I wanted it to have that sort of danger of a really beautiful stripper. It's a fragrance for a woman that wants to be taken to bed, certainly." 

No words.
