Never a dull moment with Mother Monster!

It seemed odd for Lady Gaga to shave the back of her head — even in honor of her friend — but it turns out she was just getting warmed up. Last night, Gaga got a tattoo in the shaved portion of her head: it looks like a winged cherub wearing a crown.

She got the tattoo live on stage during her FAME fragrance launch party at the Guggenheim Museum in New York. Of course, she was inked inside a giant perfume bottle while wearing lingerie, in a performance piece called "Sleeping With Gaga."

Paris Hilton and Lindsay Lohan were also there to support Gaga’s pop project.

What do you think? Can Mother Monster do no wrong or are you wondering if the fragrance fumes have gone to her head (literally)?
