Disney sweetie turned Hollywood ingenue

Lindsay Lohan

in legal trouble? Say it ain't so! LiLo, 24, who has only two weeks left in her court-ordered sojourn at the Betty Ford Center in Rancho Mirage, Calif., may find herself behind bars. Police say the

Parent Trap

star is being investigated for allegedly assaulting an unnamed female employee at the rehab.

TMZ says the Dec. 12 incident was sparked when the employee chided LiLo for returning late after spending the night at a local bar. The employee says she was attacked when she insisted LiLo take a drug and alcohol test. No arrests have been made.

TMZ says LiLo and her roommates recently were reprimanded for having a drunken party ("the booze was flowing") at one of the rehab's satellite houses.

LiLo was sent to rehab by Los Angeles Superior Court Judge Elden S. Fox, who has vowed to send the Mean Girls star to jail if she messes up while on probation.

. It drew $1 billion. Her second flick this year,

'Dallas' without J.R.!?

Here's a deep existential question: Would

Dallas

be

Dallas

if it didn't star

Larry Hagman

as that much beloved spiritual guru J.R. Ewing? That grotesque scenario seemed close to becoming a reality last week, when news spread that TNT had failed to sign Hagman for its

Dallas

redux.

Don't believe the rumors, says TV Guide mag. Hagman sure doesn't: "I hadn't heard about that, huh!" the 79-year-old TV legend tells TV Guide when told of the rumors.

Negotiations, TV Guide says, are still on.

He's a dreamy vamp, all right

Have you spent sleepless nights gnashing your teeth and wondering whether

Kristen Stewart

is getting her money's worth when it comes to romance?

Fear not, says Christina Ricci, who costars with Kristen's bf, Robert Pattinson, in Bel Ami. RoPa, Ricci tells Rachael Ray, is a "good kisser." Lest you get the wrong impression, Ricci quickly adds, "he's a lovely human being also. . . . He's just, like, a silly, fun guy. We laughed a lot. He makes fun of himself all the time. He's adorable."

Get ready for Queen Kate . . .

Queen Elizabeth II

, 84, has the ultimate wedding gift for her grandson

Prince William

: her throne. So claims

Christopher Anderson

's megahyped bodice-ripper

William and Kate: A Royal Love Story

, published Tuesday.

Anderson cites Anonymous Insider, who says the queen is considering giving up the British throne to her son Prince Charles, 62, after William marries his sweetie, Kate Middleton. William would then be next in line. (He and his wife would be King William V and Queen Catherine.)

The Biz in ShowBiz

Julie Taymor

's $65 mil Broadway musical,

Spider-Man: Turn Off the Dark

, suffered its fourth accident Monday when an actor identified by

Anonymous Sources

as

Christopher Tierney

was taken to a hospital after falling 30 feet during an aerial stunt. No comments from producers.

Paul Reubens, 58, is back on top! And back on TV. HBO on Tuesday announced that next month it will film performances of Reubens' hit stage show, The Pee-wee Herman Show on Broadway, for a special to air later in the year. The show, which features John Moody and Drew Powell, is based in part on Reubens' fab children's show, Pee-wee's Playhouse.

Al Pacino's Shylock won't be forced to leave Broadway on Jan. 9 as previously announced. Variety says the Public Theater's staging of the Bard's The Merchant of Venice has done so well it will return for an extended run Feb. 1 to 20.

Variety also says Billy Zane and Jack Huston have signed to costar with Sienna Miller and Danny Huston in Bernard Rose's next pic, Two Jacks. The pic, about a Hollywood tycoon and his family, is loosely (I'll say!) adapted from Leo Tolstoy's story "Two Hussars."

Larry King: I have loved three people

Larry King

may be done with his CNN chat show, but he's definitely not done with love.

The famously bespectacled, suspender-sporting lothario, who has been married eight times (take that, Henry VIII!), told Erica Hill Tuesday on CBS's The Early Show that he loved only three of his wives.

"I think in my life I have loved three people. Married all three," Larry said. "The other marriages, I wasn't in love. It was the thing to do, but in love - really in love - three people: current one and two others."

The current one would be Shawn Southwick, whom Larry wed in '97, and whom he was set to divorce this summer. They've since reconciled.

"There was a big difference in our ages that might have had something to do with it," says Larry, who at 77 is 26 years older. "But I'm not an expert on marriage."
