DREW BARRYMORE Never mind all the hit movies and award nominations -- the actress's life has just been made complete with a thank you in the sleeve notes of the new Radiohead album.

HUGH LAURIE The posh actor is daring to release a blues album, but at least he's anticipated the criticism: "I am a white, middle-class Englishman, openly trespassing on the music and myth of the American South. If that weren't bad enough, I'm also an actor," he says.

TWITTER Five years old this week and we have its popularity among musicians to thank for a new level of insight into their lives. How else would we have found out about Kanye West's fur pillows and Ghostface Killah's ideal soundtrack for lovemaking? REBECCA BLACK With the Californian teenager's appalling song, Friday, now approaching a frankly ridiculous 40 million views on YouTube, it's gone on sale in the iTunes store and it looks like the poor girl will actually make a lot of money from being an internet laughing stock.

KATE NASH Her sales figures may have fallen but the singer has a new cause. She's starting the Kate Nash Rock 'N Roll for Girls After School Music Club to encourage teenagers to make it in a male-dominated business.
