What better way to get attention for a cause?

Rihanna has stripped down to nothing but a Stella McCartney-designed Marilyn Monroe t-shirt to lend her support to the Comic Relief charity, and in classic fashion, found a way to make the ensemble sexy by ditching her bra and exposing what appears to be a nipple ring. Scandalous!

The British designer tweeted the pic with the caption, "Thank you @Rihanna for supporting @rednoseday! You're the best x Stella #RND."

RiRi is the latest famous face to get involved in the campaign, following in the footsteps of other celebs like Cameron Diaz and Kate Moss.

This is just the latest in a string of sultry snapshots of the singer, and as much as we love our daily dose of hotness, certain other people aren't as pleased!

"I'm not afraid of any person other than my mother, but I'm terrified of her. She called me two days ago and reeled me in about two pictures Melissa put up on Instagram, a sneak peek from a photo book she's making about me. She went crazy on me. I was embarassed. I feel like I got my ass whipped in front of my class at school. She humbled the f**k out of me," she recently confessed to Elle magazine.

Let us have our fun Mama Ri!
