Rihanna refuses to apologise for the scandalous photos she posts online, insisting the snaps give her the chance to display her true personality to fans.

The singer has published a series of controversial images on her picture-sharing Instagram blog, including saucy topless self-portraits and even shots of marijuana.

Rihanna has been accused of setting a bad example for her millions of young fans, but the defiant superstar has defended her right to share what she likes on the web.

She tells Complex magazine, "It's narcissistic, but whatever - everyone does it. I'm capturing personality... Everybody has their thing they like or don't like to see. It's all in your head. That's why people take their own pictures, because it's difficult for someone else to capture what you seek."
