So much for retirement?

Leonard Nimoy will be back on tonight's episode of "Fringe," in some form or another, as his character William Bell. (Of course it's quite possible that it's only his voice that has been "un-retired": This follows the announcement that he will be voicing the character of Sentinel Prime in "Transformers: Dark of the Moon," a nice homage to his work in 1986's "Transformers: the Movie.")

"Bellie," as Walter calls him, has been back on the show for the past few episodes, having taken residence in Olivia's body, in a brilliant Nimoy-esque performance by Anna Torv.

David Arquette is notoriously open about his personal life. During interviews with Howard Stern and Ryan Seacrest, the “Scream 4” actor discussed his separation from wife Courteney Cox, his sexual escapades and his 6-year-old daughter Coco - no holds barred.

Life.com editor-at-large Jeff Vespa was privy to the same full access when he spent three days photographing the actor – beginning on April 8, the day after Arquette reached a personal milestone: 100 days sober.

Arquette entered rehab at the start of the year to seek help for “alcohol and other issues,” People reported. He checked out nearly a month later, after completing his treatment.

Kimora Lee Simmons has indeed lost 25 pounds within the past year, but she’d like you to know that she did it in a healthy way.

Although reports spread quoting the 35-year-old saying that she lost the weight by not eating and subsisting on items like smoothies and protein bars, Simmons says in a blog post on her site that that’s not the whole story.

Those reports "led people to believe that I shed 25 lbs by not eating, which is completely ridiculous” Simmons writes. “I am a mother of three young children, two of whom are girls and I’m trying to raise them with a healthy body image. It’s taken me almost a year to lose close to 25 lbs and I did it through healthy diet and exercise.”

Neve Campbell hasn’t had to contend with "Scream's" knife-wielding masked killer in a decade, but the 37-year-old actress says that from the first day of working on “Scream 4," it was just like old times.

“It was fun. It’s not just a similar cast, but a good deal of our crew from the last 15 years, so the first days definitely felt like a reunion,” Campbell said in an interview, adding that not everything stayed the same: “Everyone’s a little bit rounder and a little bit older,” she laughed.

But keeping the heart of the cast together was crucial for Campbell as she stepped into the role of Sidney Prescott for a fourth time.

It's time to face facts, "Office" fans. Michael Scott's time with us is coming to an end very soon. Fortunately his (one assumes, temporary) replacement, Deangelo Vickers, is played by Will Ferrell.

Dunder Mifflin's past and its possible future met at a bar, not realizing whom they were meeting (and it took a long, long time for them to figure it out, even while talking to each other on the phone). No matter though, since they immediately hit it off, and the new boss was introduced in classic Michael Scott style: "Without further ado... let's all start clapping."

Deangelo's arrival had a different effect on everyone in the office: Darryl and Kevin transformed themselves, Kelly hit on him right away, the Halperts tried to use their baby to bond with him, and poor Andy was suddenly the "Office Funny Guy," and when he ran out of material started doing physical comedy.

Surprise singing sensation Rebecca Black may have her share of critics, but don't count the cast of "Glee" among them. In fact, the students of McKinley High will be performing her viral song "Friday" on an upcoming episode of the Fox series.

Though Black's video features the teen heading out for a night on the town with her female pals, it won't be the "Glee" girls who'll be singing her song, reports Vulture. Instead, Artie (Kevin McHale), Sam (Chord Overstreet), and Puck (Mark Salling) will take on the tune about weekend partying and fun.

As Marquee previously reported, "Friday" is part of a $2,000 package Black's mother paid to Ark Music Factory, an L.A.-based production company for aspiring teen singers. The video, released on YouTube, has gone on to rack up more than 100 million hits — and just as many criticisms. FULL POST

The trailer for the upcoming “Rise of the Planet of the Apes” has been released, and we're curious if we're the only ones pleasantly surprised by it.

James Franco stars as scientist Will Rodman in the "Planet of the Apes" prequel, and as the camera pans down a desolate hallway filled with flickering lights, the inescapable actor tells us that they’ve discovered a drug that “allows the brain to repair itself.”

But the drug does more than that - it also “radically increases brain function” and improves intelligence, perhaps a little too well. And then, after we see all the medical testing that Rodman's been doing on his ape friends...well, we bet you can guess what happens.
