Rihanna: I'm 'bored' of partying
Rihanna has claimed that she is no longer a party girl and that she's really "square".
The Diamonds singer, 25, said she had fallen out of love with the rock and roll lifestyle.
She told comedian Alan Carr's Chatty Man show: "Recently I've become a square. I hate partying - I don't know if it's my heels - I don't like standing up in my heels for hours.
"I don't know if it's that, but I've been so bored of it," the Daily Mirror quoted her as saying.
Asked what she did on tour after splitting from on-off lover Chris Brown, she said: "I'm such a bootleg rock star, I do nothing literally. I'm embarrassed to say that actually."
The singer, who shows off her own raunchy snaps on Twitter, added: "I love what I do and I've got a lot to celebrate. So you'll catch me celebrating every once in a while because I work hard."
Rihanna appears on the 100th edition of the Channel 4 show on Friday night.
