Spotted: Ozzy Osbourne Signs His Book Of Darkness

Every day a multitude of stars wanders through the halls of MTV News to talk about their latest projects and goof around with our intrepid correspondents. But sometimes we catch stars elsewhere, and that's why we put together Spotted!, a daily compendium of stars in the wild.

Ozzy Osbourne has had a crazy life — perhaps one of the nuttiest in rock history. It's one thing to make the transition from badass demon rocker to genial reality star and wacky dad, but it's another thing to recover from addiction and survive disaster the way he has. It's a perfect time for the Wizard of Ozz to look back on his career, and he's doing just that with his autobiography I Am Ozzy, which he signed at a Borders in New York City on Tuesday (January 26). It's the first-person account of one of rock's most iconic luminaries. Besides, it must have the story about snorting a line of ants while on tour with Mötley Crüe, so it has to be good. As Ozzy said when he announced it, "People ask me how come I'm still alive, and I don't know what to say." Now that's a book we can get behind.

Ozzy wasn't the only star taking care of business yesterday. Paris Fashion Week is in full swing, which means that plenty of stars (including Kanye West) have been making the rounds at various runway shows across France's capital city. Click here for these photos as well as the entire "Spotted!" archive, which contains over 300 candid shots of stars like Britney Spears, Madonna, Justin Timberlake, the Jonas Brothers, Beyoncé, Taylor Swift, Jay-Z, Lady Gaga, Mariah Carey, Jessica Simpson, Katy Perry, Miley Cyrus, Nick Cannon, the cast of "Glee" and Diddy!
