Wham! singer and tabloid magnet George Michael has agreed to write a “no-holds-barred” autobiography for HarperCollins. The bio, scheduled to hit bookstores in August 2009, will give in-depth insight into Michael’s personal and professional life. Judging by his recent cameo on Extras, we anticipate the tome will be at least as funny as the Slash biography. Grandmaster Flash & the Furious Five, LL Cool J and Common will be among the many rappers featured in photographs at the Smithsonian’s “Recognize! Hip-Hop and Contemporary Portraiture” exhibition, which will open on February 8th at the museum’s National Portrait Gallery. After a quiet end to 2007, Ryan Adams has taken to YouTube to get all his pent-up crazy out. Under the name D. R. Adams, the singer posts videos advertising a fake new album, dons a werewolf costume and does a pretty good Neil Young impression as he sings a new song called “Like Yesterday.” Babyshambles frontman Pete Doherty revealed that his long-delayed solo album will be released later this year. Doherty began recording the album in early 2007, but was delayed because of Doherty’s Babyshambles obligations and busy rehab schedule. Rather than fighting to regain custody of her children, Britney Spears might have another solution: Make new children. Spears and paparazzi friend Adnan Ghalib were seen shopping for home pregnancy tests during one of Spears’ many voyages to Rite Aid.
