There are still hundreds of questions lingering after the death of Michael Jackson last week, but hopefully some recent rehearsal footage will help give investigators (not to mention fans) the answers they've been looking for.

According to The Hollywood Reporter, AEG Live, the company producing Jackson's 50-concert London tour, videotaped all the rehearsals and the company has roughly 100 hours of rehearsal footage (including last Wednesday's practice run at the Staples Center, which was the night before the pop icon died). The hours of video could give clues as to how healthy Jackson was in the last two months of his life. Those backing him financially claim that the singer was fit and energetic, while many of his close friends contend that the 50-year-old was frail and out of shape.

On the bright side, the tapes include enough audio to fill two live albums worth of material, and these recordings could end up being incredibly profitable. Jackson never released a live album during his career, and fans and collectors would likely go crazy for Jackson memorabilia like this. A source tells THR, "AEG spent $30 million putting this together. The video, the lighting, the staging - it's all extraordinary. They're the first to use a new 3D projection that will blow people's minds."

As far as refunds for the shows, AEG said yesterday that the 750,000 fans who paid to attend could get a reimbursement by August 14, or they could choose to receive the actual tickets, which could be valuable collectors items. Jackson fans spent more than $90 million on the tickets, so it will be interesting to see how many of them will opt to hang on to what would have been the king of pop's last show.

OMG! Mariah Carey was snapped on the streets of NYC yesterday shooting her latest music video, and we don't even know where to begin! First of all, who knew Mariah would be game for dressing up as a dude (complete with facial hair!), and second, can she pull it off? Or is she too pretty?

MSNBC reports that a tour organizer for Michael Jackson's final concert series has announced that one tribute performance will be held in September, and it will be a replica of what was planned for “This Is It” in London.

Several high-profile singers (including Madonna) are expected to perform in place of Jackson, and while the location for the tribute concert hasn't been decided, it’s likely to take place here in Los Angeles.

Awww! Sarah Jessica Parker, hubby Matthew Broderick and their 6-year-old son James Wilkie posed for this precious photo with their newest additions to their family: twin daughters Marion and Tabitha! The girls were born last Monday in Ohio via a surrogate, and everyone looks absolutely thrilled. Congrats!

P.S. Did little James get a haircut?!

We reported earlier this afternoon that four detectives and a rep from the LA County Coroner's Office have been searching the late Michael Jackson's home in Bel Air since 11am today...

Looks like they're still there investigating, and they've already announced to the media one big discovery they've made: Large bags of pills were found in the house.

Think there's any more skeletons in the closet? We'll keep you updated with more deets as soon as we get 'em!

Denise donned a bright red frock for her day of shopping at the Malibu Country Mart. Spending that E! money, with daughter Lola in tow, Denise shopped at boutiques like Alice + Olivia and Planet Blue. It seems like all she ever does is shop, but her life is probably a lot more "complicated" than that - right?

Summer's just started for most of us, but Leighton Meester, Chace Crawford and Ed Westwick are already back to work on season 3 of their CW show! At least they had an action-packed hiatus, with plenty of sex tapes, topless photos, and magazine covers to keep us gossiping about the cast.

Sure, they're wearing a ton of makeup, but the two Gossip Guys are looking better than ever. Well, at least Ed's looking better in that suit than he does sans shirt.

And it looks like they've been joined by a new, blonde cast member who may be a love interest for Nate (before he runs of to cut Footloose, of course.) Check her out below the cut!

I'm not the biggest Katy Perry fan, admittedly, but I kinda love the fact that she's performing on stage in Madrid with a giant tube of lipstick! I feel absolutely naked without MY lipstick, and clearly so does Katy!
