LOL! RIHANNA LIVING A THUG LIFE?

RiRi is having a hard time keeping her thuggish tendencies under wraps.

The songstress, 23, unleashed another bout of Twitter photos to her followers Wednesday, but this time, her knuckles were up front and center.

In the shots, the "We Found Love" singer shows off her latest set of tattoos, letters that spell out "Thug Life" across her knuckles in a pale pink ink.

"All these b----es screaming that 2pac back," she wrote alongside one photo.

Rihanna's new ink is thought to be a tribute to late rapper Tupac Shakur, who famously had the same phrase tattooed across his stomach.

But the singer's shenanigans didn't stop there. Rihanna also tweeted a photo of her with "Machete" actor Danny Trejo, who lifted up his shirt to reveal a large tattoo on his chest of a woman with a sombrero.

The singer may also have gotten another tattoo that night - the Barbadian beauty sent out a third photo of herself propped up on her elbows with a beer in hand as a tattoo artist worked on her back.

"Tat my f--kin name on a girl so I know its real!!!" she tweeted.

Rihanna already has a number of other visible tattoos as well.

Among them are a music note on her ankle, the word "love" on her left middle finger and a trail of stars that run down the back of her neck.

Also on the back of her neck? The French phrase "Rebelle Fleur," which translates into "rebellious flower."
