Uh oh. Busted. Rihanna's love of tattoos may have just landed her in some hot water. Last night the pop star picked up a tattoo needle at a parlor in NYC and tattooed three of East Side Ink's artists with umbrellas and the letter R. Neither of the three cared that she didn't have a proper license, but the NYC Law Department feels quite differently.

Tattooing without a license is highly illegal, and according to the NYC Law Dept., Rihanna could be slapped with three misdemeanors for the offense. Each also carries its own penalty - $300 for the first offense, $500 for the second and $1000 for the third. In addition, the tattoo parlor could also face considerable fines if an investigation is opened.

Speaking with TMZ, the NYC Health Department said:

"Only licensed tattoo artists can administer tattoos in the city according to the City's Health Code. We are sending someone down to follow up on this."

The entire thing was caught on video, so it's not like either party could claim it didn't happen.
