The Lohans

Michael Lohan's girlfriend claims he's threatening her with a knife and threatening to take their infant son -- and now police are on scene ... TMZ has learned.

Kate Major blasted Lohan on Twitter Monday evening ... claiming she had to lock herself and their one-year-old son Landon in a bedroom while a knife-wielding Lohan tried to break down the door.

Threatening to take our son. What judge would rule for. him??? Stuck inside a house with this guy? He has a knife

— Kate Major (@k8major) February 18, 2014

Sources close to the couple tell us Michael is the one who called 911 when Kate started acting erratically ... and locked herself in the room.

We're told officers want one of them to leave the house immediately -- but Michael isn't budging because he thinks Kate is drunk ... and doesn't want to leave her with the baby.

We just spoke to Michael who claims Kate's been drinking again ... and it got so bad she tried to kill herself over the weekend. Lohan tells us he's worried about the welfare of their child and says he'll attempt to get custody of their son if she doesn't get help.

During Kate's twitter rant ... she addressed the suicide saying, "Someone trying to kill u is worse than trying to kill yourself ! #udontscareme."

Kate also vowed to never let Michael take their son away from her.

Lindsay Lohan spent Valentines day around the love of her life ... alcohol ... and her sister Ali Lohan.

Lilo went bar hopping with Ali Friday night in New York's East Village and both appeared to be date-free. Lindsay and Ali don't look drunk in the photos ... but the night was still young.

It's the first glimmer of pre-meltdown Lindsay Lohan we've seen in a long time -- she took the stage last night at some financier's NYC birthday to perform a classic Stevie Nicks song ... and she hit it out of the park.

Lindsay was at the Four Seasons -- where NY Republican Party Finance Committee chairman Matthew Mellon was celebrating his 50th birthday -- and she sang Stevie's "Edge of Seventeen" for the crowd.

Lindsay's had a love affair with "Edge of Seventeen" for years -- she's performed it live before and even featured a cover of the song on her 2005 album "A Little More Personal" ... a year after starring in "Mean Girls."

Looks like the Lohan clan is headed for an all out book-off ... 'cause TMZ has learned, Michael Lohan is now considering giving Dina Lohan the green light for her tell-all ... with one big fat string attached -- he gets his own book deal.

As we first reported ... Michael put the legal kibosh on Dina's book by reminding her there's a gag order from their divorce ... so she'd have to leave out plenty of the juicy details.

But now we're told Michael struck a deal with Dina's publishers at Birdstreet Books -- he'll sign a legal doc releasing Dina from the gag order ... if the company gives him his own book deal.

We're told Birdstreet already has what they believe is a lucrative contract for Michael to sign -- but it's not lucrative enough... so he's holding out.

Lindsay Lohan has no problem collecting a paycheck from convicted cocaine smugglers ... TMZ has learned.

Sources close to Lindsay tell us ... it's inconceivable that she'd bail out of the film, "Inconceivable" ... despite reports the money men -- who've backed several Hollywood movies, including "Lone Survivor" with Mark Wahlberg -- were convicted of coke trafficking.

L.A. Weekly reported the men -- Remington Chase and Stepan Martirosyan -- were convicted in 1993. There were even allegations they put a hit out on a guy in Moscow.

Our Lindsay source tells us ... she was in the dark about the guys until recently ... but she's never run from coke before ... so she's doing the movie -- period.

Here's her thinking -- film financing is a business matter and of no concern to an actor.

Lindsay Lohan claims half of her $75K coat went missing at a New York nightclub ... and it's the SAME club where she walked out with someone else's hugely expensive coat 6 years before.

We've learned Lindsay was partying at 1Oak Wednesday night. She says she went in with a $75,000 2 piece fur coat.

Lindsay claims she walked out with only one of the 2 pieces on ... and when she realized she left the other half inside she went back but it was nowhere to be seen.

We're told Lindsay called almost everyone who was at her table ... to see if anyone had walked off with the half-a-coat or knew its whereabouts.

Sources tell us ... Lindsay claims the only person who she hasn't been able to contact is a Seahawks player ... who she says was at her table.

As for the prior incident ... you may recall Lindsay was at 1Oak in 2008 when she walked out with someone's $12,000 mink coat. The owner sued Lindsay.

Lindsay Lohan ... making the case for faux fur.

Recovering addict Lindsay Lohan is taking steps to ensure she stays clean and sober ... she's put herself up for hire to spend evenings in bars and nightclubs.

Sarcasm aside -- we've learned LiLo has hooked up with some Londoners with connections to the city's hottest clubs and other night spots ... and they've negotiated deals for her to make tens of thousands of dollars in appearance fees.

We're told Lindsay has already made some appearances and more are scheduled ... she's pulling in between $5K - $15K per appearance.

She claims she's stone cold sober ... in the middle of these boozefests.

So Oprah, looks like she took your advice, right?

You want to see Lindsay Lohan naked? That's what she's afraid of ... because we know what's in her stolen computer.

Lindsay claims her computer was stolen at the airport in Shanghai, China, and she's offering a reward for its return. In a move showing an utter lack of sophistication, Lindsay isn't specifying how much she'll give ... she's saying, "Whatever it takes." Translation: A lot.

Why, you ask, is she so freaked out? We've learned she had a bunch of nude photos of herself. She claims they're all from various photo shoots that were never supposed to be released. Again, when an actress is asked to take her clothes off, usually no good comes from that.

And there's more ... We're told Lindsay claims she has "private correspondence" from a bunch of famous people, including Woody Allen and Lady Gaga, that she wants to keep under wraps.

We pressed on whether there were selfies but got no answer ... so we're guessing there are.

Dina Lohan seemed authentically shocked that her lawyer spent New Year's Eve sober as a judge ... and speaking of which ...

Watch the video (1 minute in) ... kinda hysterical -- it seems Dina just can't believe her lawyer didn't hit the bottle. As for her ... she says she stayed home.

Now staying home could still mean she boozed it up, but inside court Dina told the judge in her DWI case she's stone cold sober and is half way through her 12-step program, consistently testing negative for drugs and alcohol.

So Dina's back in court in March, when presumably she'll have completed all 12 steps and the DWI case will be resolved.

Lindsay Lohan is battling Paris Hilton on a new front -- she's toying with the idea of becoming a DJ.

Lindsay was a hanger-on at Pier 94 in NYC Monday night ... studying 2 very famous spinners -- Diplo and Jillionaire of Major Lazer.

She wasn't spinning, but she was getting pointers from the 2 guys for hours.

TMZ broke the story ... Lindsay wants to resurrect her music career ... this time around focusing on electronic dance music.

Lindsay Lohan -- already one of the top 5 DJs in the world.

The criminal investigation into the brutal beatdown of Paris' Hilton's brother is on ice ... because Barron Hilton is not cooperating ... TMZ has learned.

TMZ broke the story ... Lindsay Lohan's buddy, Ray LeMoine, smashed in Barron's face at an all-night rager in Miami. Barron says Lindsay instigated it, but Ray says Hilton was the aggressor.

Barron immediately filed a police report after the Dec 6 incident, but he has not cooperated with cops ... who have asked for a meeting. In fact, we're told he hasn't even answered the phone.

So the Florida State Attorney's Office tells us ... they are shelving the investigation and will ONLY fire it up again if Barron cooperates.

Paris Hilton says Lindsay Lohan is dead to her ... claiming the relationship is OVER FOR GOOD after the fight at Lindsay's party in Miami ... and the hatred is burning like a fiery ... crotch.

Hilton was at LAX this weekend and with a smile on her face, told photogs Lindsay is on her "naughty list" this year ... and that she would NEVER make up with her former party pal.

And that was Paris being NICE ... 'cause privately, we know Paris HATES LINDSAY'S GUTS ... and still believes she's the stinky, disgusting "firecrotch" that her pal Brandon Davis ranted about a few years back.

Bottom line -- Lindsay shouldn't expect a Christmas card this year. Or next year ... or the year after that.

Lindsay Lohan -- forever in search of a career resurrection -- is now setting her sights on reigniting her singing career ... TMZ has learned.

Lindsay was in a New York City recording studio over the weekend, experimenting with various tracks. Lindsay has one hit under her belt -- "Confessions of a Broken Heart" -- which is in the pop genre, but we're told she's now more interested in EDM.

Our sources say Lindsay has not signed with a label yet but that's what she's gunning for.

We're told Lindsay has gotten advice and support from friends, including Lady Gaga and Max from The Wanted.

Lindsay Lohan hit the town in NYC last night, and we're happy to report ... no one got their face punched in.

Lindsay showed up at Pravda -- a caviar bar -- for an event hosted by a company that launched a new karaoke app. She showed up at 7 PM and left at 9.

As far as we can tell ... it was all surprisingly undramatic. She walked in calm, left calm and looked good.

Lindsay Lohan's new tell-all book project has a new wrinkle ... if she tells all she'll end up smack in the middle of a lawsuit between her mom and her dad.

Michael Lohan believes when it comes to writing about Lindsay's childhood, Dina Lohan will tell her daughter defamatory stories about Michael.

So we've learned Michael's lawyer just sent a threatening letter to Dina, reminding her about the gag order which was imposed in their divorce ... the gag order which states, ""The wife shall not, directly or indirectly, publish, or cause to be published, any diary, memoir, letter, story" blah blah blah involving her marriage to Michael.

The Lohan's have a lot to tell, if they tell the truth.

Lindsay Lohan has decided to open the flood gates -- penning a gritty, tell-all book about EVERYTHING ... her arrests, her drug abuse, her acting career, and her family ... and she's already gotten several serious publishing offers.

Sources familiar with the situation tell TMZ, the book started as a series of journal entries, which she wrote in rehab as a therapeutic exercise. The book is still in its early stages, and it doesn't have a clear focus, but she says she wants to open up every part of her life.;

Lindsay met with a huge literary agency in NYC Thursday -- Waxman Leavall, which has repped tons of celebs who wrote books, including Victor Cruz, Novak Djokovic, Bill Murray, Brock Lesnar, and Cal Ripken Jr.

The meeting was filmed as part of Lindsay's docu-series on OWN.

Here's the problem -- it's Lindsay's life as told by Lindsay, which means we'll be reading her version of events.

So we gotta ask ...
