"Teen Mom" star Amber Portwood has been released from jail -- again -- after a judge gave her a 10 millionth chance.

As we reported, Amber was arrested and thrown in the slammer in Madison County, Indiana last week for skipping a drug court appointment -- and allegedly lying about it.

But sources tell TMZ, the judge took pity on her Thursday -- and decided to release her back to home detention.

The judge told Amber he wants her to continue drug rehab treatment and find a real job.

But if Amber screws up again, she could be thrown out of the drug court program entirely -- at which point she'll face her original prison sentence stemming from her December drug arrest ... a terrifying 5 years behind bars.

The choice is hers.

So this what it looks like to make $20 BILLION in one day.

28-year-old Facebook founder Mark Zuckerberg surfaced moments ago outside his home in Palo Alto, CA -- just hours after his Facebook IPO earned him an extra $20 billion -- and he looked happier (and richer) than ever.

But everyone else wasn't so lucky -- Facebook's stock was originally priced at $38 and finished the day at $38.23 ... not bad, but not great either.

To put it in perspective, Google's stock was priced at $85 during its IPO in 2004, and finished its first day at $100.34.

Former WWE superstar Chyna collapsed in front of the main stage at a XXX convention in Miami moments ago ... TMZ has learned.

Sources at the scene tell us ... Chyna was hanging out at the 2012 Exxxotica Expo when she suddenly dropped to floor.

We're told several people rushed over to help ... and carried Chyna out of the expo and into a nearby hotel where she's now resting.


Sources say Chyna was checked out by paramedics at the scene -- who didn't feel the porn star needed to be hospitalized.

We reached out to Chyna -- so far, no word back ... but we do know she's canceled a Friday afternoon appearance at the XBiz Summit -- another porn convention.

Will Smith just slapped a Ukrainian reporter across the face at the Moscow premiere of "Men in Black 3" -- and it was all caught on tape.

The Ukrainian reporter tries to kiss Will on the lips on the red carpet and the actor angrily pushes him away and then backhands him across the face.

You can clearly see that Will is incredibly pissed that the guy showed overt affection toward him.

After Will slaps the guy, Will says, "He's lucky I didn't sucker punch him."

We're told the dude who kissed Will is a television reporter who often kisses celebrities -- it's his schtick.

For the record, Will just came out in support of gay marriage.

A source on scene tells TMZ, the reporter's mouth brushed up against Will's and that's why the actor reacted so violently. Despite the incident, Will stayed positive ... and happily continued to sign autographs for fans and do red carpet interviews.

Mila Kunis may now work out in peace -- because the man accused of stalking the actress outside her gym has just been ordered to stay the hell away from her ... presuming he can even bail out of jail.

27-year-old Stuart Lynn Dunn was charged with two counts of felony stalking after cops say he followed Mila to her L.A. gym several times earlier this month and waited for her in the parking lot.


Dunn pled "not guilty" today in court -- where the judge then issued the protective order, barring him from harassing, threatening, assaulting, following, or contacting Mila in any way.

The protective order was issued as a condition of bail while Dunn awaits trial.

Bail was set at $150,000 -- much higher than usual in cases like this.

Dunn's due back in court May 31st.

Even rockstars can get tired ... and TMZ has learned that's exactly why Van Halen decided to postpone 31 upcoming concert dates.

Sources close to the band tell us ... the guys felt like the current schedule was "too much, too fast" ... and they were "losing their focus."

One source tells us, "They're simply burned out" ... adding, "They want to make sure their concerts are not a routine ... they want every performance to be special."

We're told the guys want to take some time to "re-charge their engines" ... so they can rock all 31 cities the way Van Halen fans expect to be rocked.

As for rumors that Eddie Van Halen and David Lee Roth are feuding ... we're told "It's total B.S."

Jackie Chan's fighting days are OVER ... at least on camera ... 'cause the legendary actor says he's giving up action movies so he can become "the Asian Robert De Niro."

The 58-year-old was promoting his 100th flick, "Chinese Zodiac" earlier today -- when he told reporters, "This will be my last action movie."

He explained, "I tell you, I am not young any more ... I am really, really tired."

Chan -- who has famously performed his own stunts for decades -- added, "The world is too violent now. It's a dilemma because I like action, but I don't like the violence."

He continued, "I don't just want to be an action star ... I want to be a true actor. I want to be an Asian Robert De Niro."

"I want to get rid of my image. So, for the last ten years I've done other films like 'The Karate Kid' where I'd rather play an old man. I want the audience to know I'm not just about fighting or comedy, also I can act."

Chan has suffered countless injuries on the sets of his movies ... and FUN FACT -- he appeared as an uncredited prison thug in the Bruce Lee classic, "Enter the Dragon" back in 1973.

Phillip Phillips -- one of the finalists on "American Idol" -- has been URGED by his personal doctor to get surgery immediately ... but Phillip wants to work through the pain and the risk so he can win next week.

Multiple "Idol" sources tell us ... when Phillip went back home to Georgia last Saturday ... his family doctor spent almost the entire stay by his side and was alarmed by what he saw -- Phillip wasn't eating and looked horrible. 

Phillip suffers from severe kidney problems and at the beginning of the competition it got so bad he had a stent put in as a temporary fix until he could have surgery. But the condition has worsened and Phillip's doc told him he needed surgery now. Phillip said he was not going to drop out of the show so the doctor told him he ABSOLUTELY had to go under the knife immediately after the finale.

We're told the recovery time for the surgery is at least 6 weeks.

Phillip's condition is taking its toll -- we're told the medication causes dry mouth, and it's had some impact on his singing.

Phillip has also missed some of the field productions that are shot for the show -- including the Ford commercials. Our "Idol" sources tell us they felt that making him go on location for these shoots were just too taxing.

Looks like Paul McCartney's title as world's richest entertainer is safe ... 'cause Bono says his stake in Facebook will NOT push him into the number one spot.

Bono was in D.C. this morning to attend a fundraiser for President Obama ... when a Washington Times photog asked about reports that the U2 frontman's $90 million investment into Mark Zuckerberg's social network will be worth $1.5 billion by the end of the day ... making him the richest rocker on Earth.

FYI -- It's been widely reported that Bono's investment company, Elevation Partners, bought up 2.3% of the company in 2009.

But Bono didn't appear too stoked about it ... in fact, he cast doubt on the entire story.

That ... or maybe he's just trying to be modest.

The video first appeared on The Washington Times.

Kim Kardashian and Kanye West are drawing HUGE crowds of adoring fans overseas on their trip to London -- but one might be attracting more fans than the other ... and you'll never guess who ...

Kim and Kanye left the Radio 1 studios in the Big Smoke yesterday -- where Kim was promoting the upcoming season of "Keeping Up with the Kardashians" -- and on their way out the crowd went wild, screaming their names and asking for autographs.

But the fans seemed to be shouting one name louder than the other -- Kim! Kim! KIM!

So we gotta ask ...

Here's hoping you enjoyed your soggy-ass cereal this morning -- because the people over at Facebook are celebrating their big IPO day ... by dining on cran-orange scones, coconut mango smoothies, and sausage hash.

It's all being offered at one of the cafes located at Facebook headquarters in Menlo Park, CA -- where FB staffers dine for free -- and the complimentary menu is claw-your-own-eyes-out delicious.

Here's a full breakdown:

Strawberry banana soy smoothies, coconut mango smoothies, whole wheat cranberry orange scones, sausage and biscuit hash with cream gravy, whole wheat choco-chip pancakes with vanilla whipped cream, whole wheat low fat flax waffles, and old-fashioned buttermilk pancakes.

Most of you have already killed yourselves by now, so we'll stop there.

Being rich is so much better than being not rich.

Most people go to Boa for steak ... Pam Anderson goes to Boa to lap dance ... and the crotch-grinding was all caught on tape.

The 44-year-old former "Baywatch" star hit up the restaurant after the L.A. Kings playoff victory last night ... and she was in the mood to party.

Pam was hanging out at a table in the front of the restaurant with a bunch of guys ...and after a few swigs of vino ... a sexually-charged Anderson offered up some quality table-dances to some of her friends.

Isn't is great when the Kings win?

Mark Zuckerberg just rang the NASDAQ bell ... opening a trading day in which the 28-year-old is expected to make more than 20 BILLION DOLLARS.

In case you haven't heard, the Facebook stock officially begins trading today -- the largest Internet IPO in history.

Zuckerberg performed the bell-ringing via satellite ... from the Facebook offices in Menlo Park, CA.  Of course, he was wearing his signature hoodie and the kind of smile you'd have on your face if you were in his flip-flops.

The stock price debuted at $38 dollars per share, quickly rose to $42, and then began leveling off. According to CNBC, 82 million shares were traded in the first 30 seconds.

It's not just Mark who's set to rake in a fortune today -- according to reports, more than 1,000 people will become overnight millionaires due to the initial public offering.

So how did the Facebook staff prepare for the big day? Hackathon.

A rep for the company tells us, "Every few months they have a hackathon, where everyone builds prototypes for new ideas they have. At the end, the whole team gets together and looks at everything that has been built. Many of our most successful products came out of hackathons, including Timeline, chat, video, our mobile development framework."
