DEBBIE ROWE To Testify About MJ's Shocking Drug Use

Debbie Rowe will testify in the Michael Jackson wrongful death case that MJ was a SECRET, hardcore drug addict for decades -- testimony that could severely damage the Jackson's case.

Sources connected with the trial tell TMZ ... Rowe will be called by AEG Live Tuesday or Wednesday ... and she'll testify that in the '80s and '90s ... she knew Michael was abusing some prescription meds, but had no idea his habit was so out of control.

We're told Rowe will point the finger at her former boss, MJ's go-to doc, Arnie Klein.  Rowe will testify she learned after the fact that Klein had a standing order ... when Michael came to the office he should be injected with Demerol and Vistaril (which makes the Demerol stronger).  

Rowe will say Michael kept the extent of his drug abuse a secret from her -- something that will clearly help AEG, because the company is arguing it had no reason to know Michael was a drug abuser.

Rowe will say she saw Michael on TMZ coming out of Klein's office days before he died -- looking totally out of it.  We're told she will say she called Klein after Michael died and said, "What the f**k did you give him?  He's dead and it's your fault."  She then hung up on him.

Rowe's testimony will further help AEG because she'll say she had no idea Michael was secretly going to surgical offices specifically for the purpose of getting high and going to sleep.

She'll also say she's the only person in Michael's world who could control him -- that she's the only one (including Michael's family) who would say "NO."

The testimony could be critical.  If the jury believes Michael could hide his hardcore drug use, AEG would have no reason to sound an alarm or take preventative action.

Smooches: Jay Z Surprises Beyonce With An Onstage Kiss in Philadelphia

As if we needed another reminder that Beyonce and Jay Z are the cutest couple in the music industry (and the universe, probably), a fan video of the lovebirds has surfaced.

During each and every show on the Mrs. Carter Show world tour, Queen B takes a few minutes to thank her backup singers, dancers and crew. On Thursday, Beyonce got quite the surprise from her hubby while doing her round of thanks at the Wells Fargo Center in Philadelphia.

Of course, Beyonce’s own photographer was there to capture the adorable moment -- she later posted the pictures on Tumblr.

“Did I really surprise you? Here’s a hug and a kiss.”

“Thanks Jay. Now let me get back to my world tour.”

Ben Foster in Talks to Play Lance Armstrong

See the resemblance? Ben Foster is reportedly in talks to play Lance Armstrong in a biopic directed by Stephen Frears. The movie is being written byJohn Hodge.

Foster stars in the upcoming Ain't Them Bodies Saints, Kill Your Darlings andLone Survivor. He also recently replaced Shia LaBeouf in a Broadway production of Orphans after LaBeouf famously trashed the production.

In other Lance Armstrong news, a documentary about the fallen hero has just beenpicked up for distribution by Sony Pictures Classics. Documentarian Alex Gibneyfollowed Armstrong since his 2009 return to the Tour de France, through a federal criminal investigation, an investigation by the U.S. Anti-Doping Agency and his admission to taking performance-enhancing drugs.

What was intended to be the documentation of an historic comeback turned into a front row ticket to watch the complete collapse of a one-time legend. It will be called The Armstrong Lie. The documentary apparently includes interviews with Armstrong's former teammates, doctors, professionals and Armstrong himself.

"On this long-distance ride, full of unpredictable twists and turns, I learned a lot about one spectacular sport – cycling – as well as the ethic of winning at all costs that pervades most sports and society-at-large," Gibney said of making the documentary.

Gibney previously won an Academy Award for Taxi to the Dark Side. He also recently released We Steal Secrets: The Story of WikiLeaks. The Armstrong Lieis set to come out this year.
