In support of Red Nose Day (Mar. 15)–a UK campaign the asks people to support a charity–a red-lipped RiRi posed bottoms-less in a campaign t-shirt designed by Stella McCartney to raise awareness. Emblazoned across the white top is Hollywood icon Marilyn Monroe dripping in diamonds and rocking huge nerd specs and a red nose. Proceeds from the funny tee will go to Comic Relief, an organization aimed at helping people in the world’s poorest countries.
The English fashion designer thanked the rockstar via Twitter.
Rihanna is scheduled to pick up her tour dates on Thursday (Mar. 14) in Philadelphia.
