Celebrity Roundup: March 16, 2012

• Is Robert Downey, Jr. Outing Dark Celebrity Secrets? [Gawker]

An anonymous commenter on a blog posting Hollywood blind items has been naming names about some of the most shocking blinds—including an actress with a penchant for abuse rumored to be Hayden Panettiere, and the violent rape of Natalie Wood, purportedly at the hands of Kirk Douglas. Now speculation is rampant that the anonymous commenter is Robert Downey, Jr. Following a long history of substance abuse issues, it seems more than possible that Downey has developed enough of a conscience in sobriety to start calling out morally reprehensible behavior—although one would think all those trips to rehab might have taught him more discretion.

• Jeremy Lin Honored With Namesake Marijuana Strain [USA Today]

The Lin-sanity over basketball player Jeremy Lin may have reached its apex when photos of a cannabis strain titled “Lin Sanity OG” went viral on Twitter after being posted by rapper Stalley. Could be a calmer influence than the pundits and commentators who can’t stop talking overexcitedly about the Knicks guard.

• Courtney Love’s Ex-Assistant Shopping Tell-All Book [NY Daily News]

Perhaps she was inspired by The Fix’s recent ebook about notorious rocker Courtney Love; now her former assistant, Jessica Labrie, is shopping a new book about her experiences working for Love. The book’s tentative title is, ominously, Get Me a Xanax.

• Sienna Miller Vents About “Medicated” Hollywood Culture [Metro]

Actress Sienna Miller has slammed the corrupt medical community in Hollywood, as well as the celebs who get hooked on prescription pills. “‘Everyone’s on something there,” she says of the Los Angeles entertainment culture. “It’s the most medicated place, there’s a whole massive market for really addictive drugs.” Specifically, she complains about being prescribed Vicodin—which she calls “prescription heroin”—when she didn’t really need it. Perhaps she hasn’t heard that prescription heroin is the new heroin.

Reservoir Dogs actor Michael Madsen was arrested last weekend for child cruelty after an altercation with his teenage son. Authorities reported that Madsen appeared to be drunk when he was arrested, but the conflict with his son developed after Madsen found the boy smoking marijuana. Addiction: a family disease.
