Sideshow | 'Prince' von Anhalt, in a royal snit, sues Bill O'Reilly

Prince Frederic von Anhalt

, who doesn't actually hold a title, has filed a $10 mil defamation lawsuit against the prince of princes,

Bill O'Reilly

, for calling him a "fraud" just because he claimed he might be the father of

Anna Nicole Smith

's baby.

Von Anhalt, who married Zsa Zsa Gabor as a sign of his noblesse oblige, said he has endured pain unendurable, hardship never-ending - even public stonings (OK, not those) - since the No-Spin Zone Avenger mocked him on TV.

People actually stare at him, he said.

The scorn is even worse online: "I get lots of e-mails from people bad-mouthing me." (Dude, call in the SWAT team.)

On his Feb. 23 show, O'Reilly also called the Eurosuave von Anhalt, who claims he had a decade-long fling with Smith, a "nut." O'Reilly immediately qualified it: "I say nut in an affectionate way." No comment from Fox.

Could that fabulous adventurer Sinbad the Sailor, from

The Arabian Nights

, really be dead? That's what that wickedly radical exercise in intellectual democracy, Wikipedia, reported all week. Surely they didn't mean

David Adkins

, the young, trim, healthy 50-year-old comedian who goes by the stage name

Sinbad

? But they did.

Oops

.

The site, a "free encyclopedia that anyone can edit," has fallen victim to some joker who wrote that the comic had died of a heart attack, first posting it on Saturday.

"Saturday I rose from the dead and then died again," said the Houseguest star. As of yesterday afternoon, Sinbad's page on the site was locked down "to deal with vandalism."

Brangelina

's decision to adopt another child was an inspiration, as is the boy's lovely name,

Pax Thien

, which means "peaceful sky" in Latin-Vietnamese. (

Latinamese

?)

But this is not the child's birth name.

Angie threw that name, Pham Quang Sang, which means "brilliant," into the garbage (as it were).

Pax is no baby: He's 31/2, which means Angie will have to teach him to learn to refer to himself by his new name. He'll become other to himself, a Pham who'll have to befriend this new kid Pax. Perhaps Pax'll turn out to be a real creep and a jerk who bullies poor Pham! A pox on Pax!

We're not immortal, you and I. Nor is

The Sopranos

. Face it, the HBO show is headed for oblivion. But not just yet!

The final nine episodes of the outstanding mob soap start April 8.

The

New York Collegium

's debut at the Bach Festival of Philadelphia yesterday also resembled a farewell: The Collegium is going on hiatus for a season to regroup and improve its financial situation.

"The doors aren't closing on the Collegium by any stretch," said exec director Michael Scagnoli. Celebrated early-music specialist Andrew Parrott will continue as music director. And the Collegium will pursue relationships in Philly. Early-music groups have traditionally had problems in New York, due to competition from what are considered to be better such specialists touring from Europe. Philly doesn't have that problem.

Even as one

Lohan

is back on his feet, another stumbles.

Pa Michael Lohan is out after serving nearly two years in a New York state prison for drunken driving and assault. He vows he'll be sober, "walking the walk" from now on. And he wants to heal his broken relationship with Lindsay.

But that'll have to wait: The New York Post says L.L. left the sober bosom of a California rehab for a weeklong club hop in Manhattan, where, anon. sources report, the star was back in the traitorous arms of that slutty stepma, Booze. A rep for Lindsay nondenial/denialed that the actress is "taking her life day by day."

Aren't we all, sister?
