Rihanna has some new controversial ink!

Never one to err on the conservative side of things, the 23-year-old singer took her daring looks to a new level on Tuesday with a brand-new tattoo that pays homage to the late Tupac Shakur.

"All these b*tches screaming that 2pac back #THUGLIFE," the "We Found Love" singer tweeted with a pic showing off her new ink: "THUG LIFE" written across her knuckles on both hands. Tupac, who was murdered in Las Vegas in 1996, had the exact same phrase tattooed on his stomach.

Rihanna is fresh off her trip in Hawaii, where she showed off her figure in several revealing bathing suits and was photographed smoking what appeared to be marijuana.

During her stay, she also managed to run into Danny Trejo, the 67-year-old actor who's been in and out of jail, while in tattoo artist Mark Mahoney's shop.

"Look who's in the #TATTOO parlor...Danny Trejo #G4L p.s. Look up his story!" the star tweeted.

It's been reported that the Barbados beauty has up to 15 tattoos now, including a small gun on her rib cage, a skull on her ankle and the words "rebelle fleur" (French for rebellious flower) on the back of her neck.

Another controversial development in her life? Last week, Us Weekly broke the news that Rihanna and ex Chris Brown (who infamously assaulted her in 2009) have been secretly hooking up for nearly a year. "There's no denying they can't get enough of each other," a pal told Us. "I don't see it ending well."
