T.R. Knight exits 'Grey's Anatomy'

Fall's still months away, but one of last season's bigger Grey's Anatomy cliffhangers has already been resolved: Sources confirm to me exclusively that T.R. Knight's wish to be released from his contract has been granted. The official decision, I'm told, came down in the past few days, just as many of his castmates began receiving their formal pickup letters from ABC.

Knight's departure would seem to confirm that George doesn't survive, although fans have wondered whether Rhimes is planning to pull an Elizabeth Reaser (Jane Doe/Rebecca) and have him live, only to be replaced by another actor, thanks to plastic surgeon Sloane's handiwork. That's "hilarious, ridiculous," the boss has said. However, I've heard that she was interested in having Knight appear in next season's first three episodes, but a short-term deal could not be brokered.

Smallville Casting Exclusive: Brian Austin Green Is Metallo

David Silver has traded rap for heavy metal.

Brian Austin Green has been cast on Smallville as the DC Comics villain Metallo, TVGuide.com has learned exclusively.

That's right — the Terminator alum is now playing a cyborg himself.

Green will appear as the kryptonite-powered villain (alter ego "Daily Planet" journo John Corben) in at least the first two episodes of Season 9, which kicks off Friday, Sept. 25.

Green's Smallville gig comes on the heels of the Beverly Hills 90210 alum passing on the role of One Tree Hill sports agent Clayton.

Green had been attached to the CW pilot Body Politic, but that series did not get picked up for fall.

This past TV season, Green costarred on Terminator: The Sarah Connor Chronicles, which was canceled after two seasons.

iPhone 3.0: Say 'Hello' to Copy and Paste

iPhone 3.0 upgrade day is finally here -- we've been waiting impatiently for it ever since it was announced back in March. It may sound absurd that a simple software update is generating so much buzz, but 3.0 packs so many features that users have been clamoring for. While AT&T customers will just have to wait for MMS (you can finally send media like pictures and movies via text message) and tethering until the carrier turns on the features, everyone will be able to immediately take advantage of copy-and-paste, landscape keyboard features, push notifications, and new Bluetooth profiles for stereo headphones and P2P data transfer. The update went live at 1pm EST, so just plug in your iPhone or iPod touch (don't forget about that $9.95 upgrade fee for the touch) and get your updating on. And remember, everyone else is likely rushing to download the latest update at the same time, so just relax if it seems to take a while. Your patience will be rewarded.

What's Michael Phelps Sporting?

Look at the scruff that Michael Phelps is sporting.  He's beginning to look like Yosemite Sam!

Michigan man claims he was N.Y. boy who vanished in 1955

For more than a half-century Jerry and Marilyn Damman wondered what happened to their 2-year-old boy, who mysteriously vanished into thin air outside a Long Island bakery.

Now, 54 years later, a Michigan man claims he is the missing child whose name was Steven Damman.  So far, authorities will not release the Michigan man's identity and won't say why he believes he is Steven Damman. The FBI is conducting DNA testing.

This will be such a great story of hope for those who have lost their children but it is also a reminder of just how quickly our children can be taken away from us.  

The Bangles, '80s hitmakers, still making sweet harmony

While shoulder pads and big hair are no longer part of the Bangles' repertoire, those glorious harmonies remain.

The '80s band (whose members aren't entirely sold on that description) recently powered through a set at Sirus XM Radio's New York headquarters as part of the company's "Artist Confidential" series.

An audience of happy fans watched from outside a studio as Susanna Hoffs and sisters Vicki and Debbi Peterson attempted to rattle the glass walls with the melodious "Manic Monday" and an electric "Hazy Shade of Winter." 

Adam Lambert goes GaGa

We may not know exactly what Adam Lambert’s debut album will sound like, but we do now know at least one of the project’s producers.

This season’s “American Idol” runner-up confirmed that he is working with RedOne, producer for Lady GaGa.

“I can say that is true,” Lambert said. “We have been writing the past couple days and I think we’re going to come out with some amazing tunes. I’m going to have my own sound but I do love Lady Gaga. I’m a huge fan.”

The glam rocker gets chatty about Perez Hilton’s “crush” on him, dealing with his newfound celebrity status and reuniting with fellow contestants.

He also reveals that he’s been rubbing shoulders with some big-name artists since the show ended, including Usher, Enrique Iglesias and Madonna.  With so much star power circling in Lambert’s universe, might he be lining up some killer duets for his project?
