Sideshow | Hilton checks in to hoosegow

Paris Hilton

meant it when she told the throngs at the MTV Movie Awards on Sunday, "I'm ready to face my sentence."

Just hours later, she traded in the sleeveless black number she wore at the glitztavaganza at the Gibson Amphitheatre for a jumpsuit by that rad designer, the California Department of Corrections.

Paris, 26, surrendered her corporeal, if not her pneumatic, self at the Men's Central Jail in downtown L.A. at 10:30 p.m. The Simple Life role model was then taken to the Century Regional Detention Facility in Lynwood, Calif., where she'll spend 23 days for violating probation in a reckless-driving case.

Paris told the MTV crowds she eschewed paying to stay at a jail of her choice - an option open to richies. (Zsa Zsa Gabor paid $85 a day for a three-day turn in jail in '90.) "I did have a choice to go to a pay jail," Paris said. "But I declined because I feel like the media portrays me in a way that I'm not and that's why I wanted to go to county, to show that I can do it and I'm going to be treated like everyone else."

Wire reports yesterday indicated that Paris successfully completed her first night.

One down; 22 to go.

NBC is atwitter and aflutter, even a bit woozy over its latest coup: The network has secured what a release proudly yells out is the "first-ever American television interview" with Brit royals,

Prince William

and

Prince Harry

of Wales. The sitdown will air June 18 on

Today

and

Dateline NBC

.

Conducted by none other than Matt Lauer - who was once accused of being "glib" by Tom Cruise - the interview marks the 10th anniversary of the death of the princes' mother, Princess Diana, who was killed in a car crash in August '97. The young men, NBC says, tell Lauer about a London concert they are organizing in honor of their mother on her birthday, July 1.

NBC also plans a bucketful of other Diana- and royals-related programs throughout the summer. It will be shmashing.

Rosie O'Donnell

,

The View

's former in-house loudmouth and foil for

Elisabeth Hasselbeck

, took BookExpo America by storm Sunday, where she was shilling her memoirs,

Celebrity Detox

, due out Sept. 18.

"The book opens on my first day on The View," said Rosie, capitalizing on her overpublicized exit from the show. "We had to change the epilogue," she said, now that The View is no longer part of her life.

Rosie, who famously tried to undo her celeb status after she left her talk show in '02 (sound familiar?), awkwardly rehashed her book's thesis: "If celebrity and fame are truly a drug," she told the gathered book lovers, "can one go back to drinking and sip instead of taking a slug?"

I think Rosie's trying to ask whether she can be a celeb again but without killing herself in the process. (But if we're to follow Rosie's own addiction metaphor, it should be pointed out that rehab programs say you should never pick up any substances after quitting. Ever.)

Black. Apatow. Wilson. Ramis

.

Giant men. Men who'll get The Job Done.

Yes, multitalented actor, writer, filmmaker, singer, lover, dude Jack Black will join forces with producer Judd Apatow of Knocked Up fame, exec producer Owen Wilson of Owen Wilson fame, and the legendary Caddyshack director Harold Ramis for the new comedy Year One. Although Variety's report did not indicate what the movie's about or when it comes out, we already know it'll be huge.

Though it has yet to take any action, the U.S. Mint has decreed that 20th Century Fox's publicity stunt for its summer blockbuster,

Fantastic Four: Rise of the Silver Surfer

, is illegal, the New York Times reports.

In its zeal to promote - promote! promote! - the film, Fox hired the Franklin Mint to put a color image of the Silver Surfer on the backs of 40,000 quarters. The U.S. Mint objected, citing a law that says it is illegal to advertise on coins. But in a Wile E. Coyote move, the private, for-profit Franklin Mint says the coins don't advertise the flick, but are "commemorative" collector pieces.

The brouhaha's been good for biz: Some collectors have sold the coins on eBay for as much as $149 a piece.

Product hype:

American Idol

finalist

Constantine Maroulis

will release his solo record,

Constantine

, Aug. 7. The Brooklyn-born Greek American is also an actor. He was like a featured player on

The Bold and the Beautiful

for an episode that also debuted his single, "Everybody Loves." C. has also starred on Broadway in

The Wedding Singer

.

Constantine became famous on Idol for flashing his soulful eyes and shaking his flowing shoulder-length Jesus-era prophet hairdo as he sang, which made the girls shriek in the audience.

The Times of India reports that former star pugilist and brutish thug

Mike Tyson

is, well, basically not Mike Tyson anymore:

Iron Mike

, who recently appeared - as a

dancing

Mike Tyson - in a promo music video for the Bollywood film

Fool n Final

, says he's got the itch to star in a movie himself. And, he said

Fool

producer

Firoz Nadiadwala

had already approached him with a script.

Iron Mike says thespians and boxers have much in common: "In both the fields, in order to survive and triumph, you need focus and to be highly disciplined and determined."

In a less sunny report, the New York Post says that in her new autobiography,

Grace Will Lead Me Home

, Iron Mike's ex-wife

Robin Givens

alleges a drunken Tyson violently raped her during an '88 trip to Russia.

In a graphic report, Givens says Tyson woke her up in the middle of the night, "climbed on top of me . . . and grabbed me by my throat." She writes that later that night Tyson climbed over a railing 18 floors above a hotel lobby and threatened suicide. The Post notes that two days after the incident, the couple gave their now-infamous 20/20 interview, during which Givens told Barbara Walters that life with Tyson was "torture, pure hell."
