Sideshow: Fallon to take 'Tonight' chair

Big, even drastic, changes are coming to your late-night TV screens.

NBC plans to install Jimmy Fallon as its next despotic leader on the Tonight Show Throne of Swords when current host Jay Leno's contract expires in the fall of 2014, the New York Times reports.

But the drastic changes to come don't end there: The network also plans to move the show back to its original home, New York. Fallon is so excited that he can't contain himself. Asked whether he thinks he'll be the next Tonight god, he tells GQ: "I mean, in the nicest way, who really cares. In the nicest way. It would be great, sure, I guess."

Tonight, which debuted in 1954, was beamed out of New York by its first two hosts, Steve Allen and later Jack Paar. It was moved out west in '72 by the late, great Johnny Carson. Fallon is already in place: His Late Night is shot at NBC's Studios at 30 Rockefeller Center. The Hollywood Reporter says the network will officially announce the changes in May.

One issue has yet to be addressed: Will Fallon keep that eclectic hip-'n'-trip-hop Philadelphia band the Roots as the Tonight house band? And who will replace Jimmy on his show?

Yep, the Fallon-ator is everywhere lately, including the cover of GQ's second annual "Style Bible" special issue in April. He's one of three cover men. Other copies of the mag will feature Jason Bateman or Bruno Mars on the cover. (All three will be included in all editions regardless of the cover!)

Fallon, 38, traces the roots of his wit to a deprived childhood. "Yeah, the cool crowd was always beyond my grasp," he tells the mag. "Like, my parents had a fence, a chain-link fence, and my sister and I were not allowed outside it." The comic says his parents made him wear a football helmet whenever he used the little rope swing on a tree in his backyard. Kids mocked him.

People mag has conducted a full-on, bloody and very smelly autopsy on the Katy Perry-John Mayer relationship, which seems, unsurprisingly, to be as dead as dead can be. For now at least - they've broken up and reconciled before.

It seems that envy has reared its ugly head in the romance. According to Unnamed Perry Pals, John can't deal with Perry's universal fame, acclaim, and awesomeness. "He's very defensive and comes across as extremely jealous of her career," a Perry Pal says. Another Source says Mayer, who once said sex with his then-gf Jessica Simpson amounted to "sexual napalm," is with Perry only because of her fame! "He's basically using Katy," Pal says, "who fits into his plan to stay in the spotlight right now."

Leaving Las Vegas Oscar-winner Nicolas Cage says the best advice he received as an artist came from the redoubtable British chameleon David Bowie.

"I asked him once how he managed to do all the things he's done. He said, 'Whatever makes you feel uncomfortable, try that. It's the only thing to test you, keep you fresh,' " Cage tells USA Today. "I've tried to do that in most of my movies. I want my movies to be a reflection of where I am at this very moment." Cage's next pic, The Croods, which has him voice an animated caveman, opens Friday.

British '60s acid band Pink Floyd's classic 1973 LP Dark Side of the Moon is one of 25 recordings added this year to the Library of Congress' National Recording Registry, which preserves great recordings for posterity. Librarian James H. Billington said this year's inductees, with pieces stretching from 1918 to 1980, included the Bee Gees-dominated Saturday Night Fever sound track, a 1931 Will Rogers broadcast, pianist Van Cliburn's 1958 performance of Tchaikovsky's Piano Concerto No. 1, and music from Simon & Garfunkel, Janis Joplin's Big Brother and the Holding Company, Chubby Checker, and the Ramones. The number of registry recordings is 375.

The latest batch of promotional images of the Mad Men cast had to be airbrushed to smooth out star Jon Hamm's conspicuous masculinity, the New York Daily News says. The report has gone viral, and it has peeved Hamm's rep. "It is ridiculous," he tells the News, "and not really funny at all."

In a startling admission that had yours truly in tears all morning, comic film writer, producer, and director Judd Apatow has come out of the closet as a disgusting American man. As disgusting, sad, and pathetic as the man Paul Rudd plays in Judd's Knocked Up spin-off, This Is 40. "I relate to just being a disgusting man and feeling bad that my wife even has to be around me," Judd, who is wed to Rudd's costar Leslie Mann, tells People.

Sexy man and seriously serious thesp Ryan Gosling, 32, says he wants to take a break after he's done promoting his latest films, Only God Forgives and The Place Beyond the Pines, which costars his real-life love, Eva Mendes. "I've been doing it too much," the Drive star tells the Associated Press. "I've lost perspective on what I'm doing. I think it's good for me to take a break and reassess why I'm doing it and how I'm doing it. And I think this is probably a good way to learn about that. I need a break from myself as much as I imagine the audience does."
