For "Fringe's" first episode in its new Friday timeslot, you know they have to do something big. Not only do the mysterious Observers return, but the legendary Christopher Lloyd joins the cast as a rock musician idolized by John Noble's Walter Bishop.

Lloyd's character finds out the real reason his band broke up, and since this is "Fringe," you know there's going to be a very bizarre reason for it. “I was very excited for this role. My character is going through an experience he never expected to happen to him, and he’s adjusting to that,” he told reporters on Thursday, adding that he felt that he was welcomed in as a part of the ensemble cast.

For Noble's part, he was excited to have Lloyd as his musical hero. "“He’s one of my heroes anyway, so when Christopher came on, it was a dream come true," he said. "We had an amazing time together these two old guys, just reminiscing." FULL POST

Yes, Kara DioGuardi does plan on watching “American Idol” this season.

There don’t appear to be any hard feelings for the former judge who has now moved on to a new show. DioGuardi will be a judge on Bravo’s new show, “Platinum Hit,” which she told CNN gives a realistic look into the business of songwriting.

“It’s a process show, Bravo does those really well,” DioGuardi said. “And, of course, there is drama.”

Don’t hold it against her, but Britney Spears has another No. 1.

Her latest beat-driven single, “Hold It Against Me” peaked at the top of iTunes within hours of its release, and this week Billboard made the record’s reign official: it also debuted at No. 1 on the Billboard Hot 100.

But Spears is used to such a victory. Her 2009 hit "3" also made its bow in the top spot. Following Ms. Spears is Bruno Mars, whose single "Grenade is No. 2, and Katy Perry's "Fireworks" at No. 3.

Is this a sign that Spears’ upcoming album will also rise to No. 1? We'll have to wait and see - the album is expected to drop in March.

Justin Bieber is getting in sync with Justin Timberlake for his next record. According to Bieber's songwriter, the Bieb will imitate JT as he attempts to attract an older crowd.

"What we're trying to do with Justin is to segue him into young adulthood," tunesmith Sean Garrett tells Billboard of 16-year-old Bieber's follow-up to "My World 2.0."

"The one great thing about Justin Bieber is the fact that his fans are going to grow with him," Garrett adds. "So we want all the fans that started out with him to still be intrigued and excited about him, but we want to also stretch out a little bit and make the fans that are 22-23 years old love Justin as well."

Can’t we all just get along?

With the exception of two mags in this week's cheat sheet, it’s nothing but sadness and heartbreak. Taylor’s still getting played by Jake Gyllenhaal, Sandra Bullock’s still single (although, we’re not quite sure what’s so “heartbreaking” about that) and both Kate Hudson and Khloe Kardashian are “pregnant and betrayed”!

Thank goodness Nicole Kidman and Elton John had the foresight to respectively ring up surrogates several months back so we’d have some heartwarming baby news to help us deal with this madness.

Until next week….

Singer Eric Benet is engaged to be married to Prince's ex-wife, Manuela Testolini.

The pair live together in Los Angeles.

Fred Armisen clearly has a thing for sketch comedy.

Already well known for his portrayal of President Barack Obama, Larry King and others as a cast member on “Saturday Night Live,” Armisen is sharing his talents with the new IFC show “Portlandia.”

The project is an outgrowth of the web series “ThunderAnt,” which Armisen and friend/co-star Carrie Brownstein started a few years ago. The “SNL” star told CNN the city of Portland, Oregon, turned out to be the ideal setting.

Just when I thought “The Big Bang Theory” couldn’t get any better.

Our lovable gang of geeks got up and out of Leonard and Sheldon’s apartment for a road trip, and it was one of the funniest episodes ever. All of the guys and gals were off to the Science and Society Convention including Penny, who was along because a spa weekend was part of the package – and because Amy Farrah Fowler has decreed that they are besties.

In one car we had Howard, Bernadette and the “ever-silent-whenever-a-girl-is-present-unless-there-is-alcohol-involved” Raj.
