Sideshow: Kristen Stewart, director Rupert Sanders issue apologies for affair

Is the fairy tale over? In a revelation that has shaken the Republic to its core, Kristen Stewart, 22, has admitted she two-timed vampiric beau Robert Pattinson, 26, with Rupert Sanders, the married 41-year-old director of her fairy-tale flick Snow White and the Huntsman.

"I'm deeply sorry for the hurt and embarrassment I've caused to those close to me," K-Stew says to People.

"This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry." The mea culpa comes hours after Us Weekly uncovered the heartrending truth. Rupert, whose wife, Liberty Ross, plays K-Stew's mom in Huntsman (psychoanalyze that, baby), later issued an apology to the wife. "I am utterly distraught about the pain I have caused my family," said the father of two in People. "My beautiful wife and heavenly children are all I have in this world." No comment yet from the injured parties.

Michael Jackson's children, who have been caught in the crosshairs in an ugly family dispute over MJ's reported $500 mil estate, have been removed by court order from their legal guardian, MJ mom Katherine Jackson, who has been absent from her house for nearly two weeks.

Los Angeles County Superior Court Judge Mitchell Beckloff on Tuesday granted MJ brother Tito Jackson's 34-year-old son, Tito Jackson Jr., TJ, temporary guardianship of his cousins, Prince Michael, 15, Paris, 14, and Blanket, 10. The emergency hearing was held after an ugly incident Monday, when MJ siblings Janet, Randy, and Jermaine Jackson tried forcibly to remove the kids from Katherine's home in Calabasas, Calif.

Beckloff said he was suspending Katherine's guardianship not because of any wrongdoing on her part, but because he feared she might be "prevented from acting as a guardian because of the acts of third parties." That'd be her children, who have been up in arms ever since they learned they were cut out from MJ's will, which leaves virtually all of the singer's fortune to his three children.

What did Judge Beckloff mean by his cryptic remarks? Does he really think parties (known or unknown) are trying to stop Katherine from being an effective guardian to her grandchildren?

KJ's lawyer, Sandra Ribera, thinks so.

She told the judge at the hearing that the matriarch's two-week absence wasn't entirely voluntary. (On Monday, Katherine was found, staying with family in Arizona.)

"We have reason to believe that Mrs. Jackson has been held against her will," Ribera said. TJ also voiced concern over Katherine's safety, saying she sounded odd when she spoke to him on the phone.

"I've never heard my grandmother talk like that," said TJ, adding that he thinks she was trying to speak to him in code.

Katherine's children have been plotting against her for some time, Ribera tells FoxNews.com. No comment yet from Janet or her brothers.

The Jackson ugliness continues. In a letter obtained by Celebuzz.com, MJ sisters Janet and Rebbie and brothers Tito, Randy, and Jermaine accuse the executors of Michael's estate, John Branca and John McClain, of faking Michael's final will before his death on June 25, 2009. The executors say they will not be intimidated.

Dispirited by the (near-)collapse of the Stewart-Pattinson myth? Here's another fairy tale to warm your heart.

Brad Pitt and Angelina Jolie are sooo in love, this story goes, some believe they invented it in the first place. (Yes, love itself; love-in-itself; love-in-and-for-itself.)

So intimates the jeweler who helped Pitt design the engagement ring he gifted to his betrothed. "Brad and Angelina are a very romantic couple," says jeweler Robert Procop in an exclusive! interview with Us Weekly. Speaking as an emissary of love, and not an opportunistic scallywag shamelessly promoting his shop, Procop adds, "They always knew they'd be together forever and get married one day, right from the start."

Sharon Osbourne has decided to resign her commission as an America's Got Talent panelist. Or she has not. Gossipers issued fevered reports when, as part of some Twitter feud with fellow panelist Howard Stern, Sharon wrote, "My darling @HowardStern, money is not the reason I'm not returning to @nbcagt." NBC says it has not been informed Sharon is leaving.

Toy company MGA Entertainment has filed a $10 mil breach-of-contract suit against Her Ladyship, the Gagaest of all Gaga popstars, Lady Gaga, for backing out of a deal to have the company manufacture Gaga dolls that would sing bits of her music. (Who'd blame her?) Gaga's lawyers say it's all nonsense.

TMZ says the Orleans Parish District Attorney's Office (which does stuff about New Orleans) has decided to prosecute Russell Brand, the Brit comic once married to American singer Katy Perry, for misdemeanor criminal damage to property. It stems from a March incident in the Big Easy, when Brand allegedly threw a paparazzo's iPhone through a window.

Witnesses say that as Jennifer Lopez and her 25-year-old beau, Casper Smart, boarded a swank yacht Tuesday night in New York to celebrate her 43d birthday, they were grinning. . . .
