In a shocking joint investigation, Star and RadarOnline reveal that Lindsay Lohan, 25, uses a girlie-girl pink pen to write in her diary. Star says it has a copy of LiLo's 2008 journal, in which the thesp expresses deep romantico-sexual feelings for Heath Ledger. So was LiLo's soul entwined with Ledger's at the time of his death - a hitherto unknown fact about the great actor's life.

"Today Heath died," LiLo scribbled pinkily on Jan. 22.

"I'm in love with him. . . . He was the love of my life. He taught me so much, and he was everything I've ever wanted." There's more: "I want to hear him laugh and hold me," LiLo says. "I crave his touch and care." This line lends credence to the theory that Heath, who quit his wife Michelle Williams in '07, was LiLo's lover.

Radar says it has more proof: A recording of an '08 phone call which has LiLo mom Dina telling LiLo dad Michael that LiLo was "dating Heath when he died."

Alas, Ledger cannot defend himself.  

War: Alec Baldwin vs. American Airlines

A war this week between Alec Baldwin and American Airlines threatens to tear America apart. It began Tuesday when Alec was booted off an American Airlines Los Angeles-to-New York flight because he refused to stop playing an iPhone game and turn off his phone. The 30 Rock star didn't take it lying down. "Flight attendant on American reamed me out 4 playing WORDS W FRIENDS while we sat at the gate, not moving," he tweeted.

He later added, "American. Where retired Catholic school gym teachers from the 1950's find jobs as flight attendants."

American Airlines is not amused.

On Wednesday the company posted a detailed account of the fracas on its Facebook page. It included this: "The passenger [Alec] was extremely rude to the crew, calling them inappropriate names and using offensive language."

Alec's comeback? He shut down his Twitter account, which had 600,000 followers.

Colbert for U.S. prime minister!

Political pundit Stephen Colbert of the C-Span-ish Comedy Central channel in 2008 tried to win South Carolina's presidential primaries both as a Republican and a Democrat. He was unsuccessful.

So he's changing it up for the 2012 contest: Colbert, a Charleston, S.C., native, recently met with GOP officials in his home state in a bid to be named the official corporate sponsor of the South Carolina Republican primary.

His offer? He'll give 'em $100,000 if they rename the race "The Colbert Nation Super PAC Presidential Primary."

State officials tell the Associated Press they have ended the talks. Are they too chicken to do it?

Nude Lindsay Lohan pics! Online!

In a particularly public-spirited gesture, some unknown Great Citizen has leaked online the cover of Playboy's Lindsay Lohan edition.

Mark Zuckerberg photos online!

Angelina Jolie: Why I'm a geek

In mysterious confession, Angelina Jolie told Extra correspondent and former Philly newsman Jerry Penacoli earlier this week that she's a "closet geek."

Now she's ready to elaborate!

"I spend hours and hours to get the perfect Christmas stocking or gift bag ready," says Angie, who is raising six kids with domestic partner Brad Pitt.

"I am obsessive. . . . Brad will tell you I lose my mind for the kids' birthday parties. I will spend days working on gift bags! That's an oddity about me." Oh. Hm. OK.
