David Rainey -- AKA Puck from "The Real World" -- is going back to school -- domestic violence school ... and if he graduates with honors, he won't go to jail.

Rainey copped a plea in his criminal case -- he was accused of hurting his live-in girlfriend and faced one year in jail.

Rainey got into an argument with his girlfriend in July and allegedly scratched and bruised her ... then slammed the phone down when she tried to call 911.

Rainey pled guilty to domestic violence and dissuading a witness -- both misdemeanors. He was sentenced to 3 years probation and ordered to attend a 1-year domestic violence program.

The judge gave Rainey credit for the 15 days he spent in the slammer.

Rainey had a similar run in back in 2011, when he was arrested for felony domestic violence. And he served prison time in 2012 for stalking a woman.

Maybe these women should learn a lesson from the 1994 "Real World" housemates ... and kick his ass out.

Weston Gosa -- the dude who knocked up Whitney Purvis on "16 & Pregnant" -- was arrested again Tuesday ... and his mug shot is the absolute best of the trilogy.

Law enforcement sources tell us ... Weston was pulled over in Georgia for speeding and driving on a suspended license. He's currently being held at the Floyd County Jail in Rome, GA on a $1,710 bond.

As we previously reported -- Weston was busted last December for smashing some electronics ... and popped again last July after allegedly crashing his car while driving under the influence (which spawned the infamous "sleeping mug shot").

Are the people who cast that show that good ... or just lucky?

Jwoww isn't just gonna squeeze out a kid in July, she's also gonna push out a big ol' steaming dump ... so says her "Jersey Shore" BFF Snooki.

Jwoww made the baby announcement on Christmas Day ... and hours later, Snooki (who already has a kid) posted a screen grab of a recent text convo they had, in which Snooks eloquently describes the miracle of child birth.

As for JWoww -- real name Jenny Farley -- she posted a picture of her growing fetus on Instagram ... along with a note from herself and fiance/baby daddy Roger.

"Teen Mom" star Jenelle Evans' potty mouth got her locked up in South Carolina yesterday ... after cops tried muzzling her during an argument with her boyfriend and she refused.

Police were dispatched 2 separate times to Evans' home yesterday -- both times for loudly arguing with her boyfriend outside ... according to reports.

Cops say Jenelle's BF told them the MTV star locked him out of the house during an argument ... but he agreed to go for a walk and cool off -- so officers left.

Shortly after, they were dispatched again ... and reportedly found her boyfriend had climbed in the house through a window -- which caused Jenelle to lock herself inside the bathroom.

Police handled the situation before attempting to leave -- but Janelle started yelling cuss words outside the house ... and when she refused to stop they took her into custody for "breach of the peace."

Worst part ... Janelle is still on probation -- meaning she could be facing additional jail time if convicted.

Janelle was only in jail for about an hour.

Parenthood has clearly not cramped Pauly D's style .... he happily strolled out of Bootsy Bellows nightclub in West Hollywood late last night ... but there's no doubt -- being a father is front and center in his brain.

Check out the video ... it's not so much what Pauly says -- we know he's fighting for full custody and it's nasty -- but you can see and hear how much he loves his kid.

It's pretty rare when celebs come off so real and unfiltered.

Day 26 -- the boy band masterminded by Sean "Diddy" Combs on MTV's "Making the Band 4" -- IS TOTALLY REUNITING FOR A NEW TOUR ... TMZ has learned.

A rep for Day 26 tells us ... the band, which was handpicked by Diddy on the 2007 show, is planning a 30-city tour starting in the Spring of 2014 ... and it's gonna include ALL of the original members.

Back in the day, D26 produced 2 albums before trouble began. Qwanell "Que" Mosley was kicked out of the group in 2009 because of disagreements with management.

The whole band broke up in the summer of 2012 ... and there've been rumors of a reunion ever since. It wasn't until Que climbed on board that it became a reality.

As for Diddy ... we're told he's NOT part of the resurrected band ... but he's already given the boys his blessing.

Pauly D better learn to duck and cover ... 'cause his baby mama had no qualms about beating the crap out of another guy who knocked her up ... according to police records obtained by TMZ.

We've learned ... Amanda Markert was arrested in July 2009 for opening a can of whoopass on her first baby daddy -- Lance Gerbino -- leaving him with bloody lips, a nasty gash above his eye and injuries inside his mouth.

Gerbino tells TMZ ... Amanda had been out drinking with friends ... and was pissed because she had to come home to help take care of their infant son.

He claims Markert just started "going crazy" ... wailing on his face with her fists while she was holding their son. Gerbino felt the baby was in danger ... and that's why he called police.

According to police records, Markert turned herself in to cops --booked under her legal name, Amareda Markert -- but the assault charge was eventually dismissed after she completed an anger management course.

As we've reported, Markert and Pauly D are involved in an ugly custody fight over their 6-month old daughter, Amabella ... and they've both been very clear about how much they hate each other.

We contacted Amanda for comment on the domestic violence case ... she hung up on us.

The Situation is on the wrong end of a massive Federal criminal investigation -- which is currently focusing on the "Jersey Shore" star's cash flow ... TMZ has learned.

Sources tell us, Mike Sorrentino and his companies -- MPS Entertainment, Situation Productions, GTL Management, and his clothing line Situation Nation -- are at the center of the investigation.

The exact nature of the crime is unclear, but we know it's a felony, and appears to be finance related. We're told subpoenas have already been issued to Sitch's business associates, asking for copies of payments issued to him, copies of canceled checks, correspondence, and more.

We reached out to Situation's rep for comment. So far, no word back.

Fist pump has a whole different meaning in prison.

"Teen Mom" star Amber Portwood is no longer a prisoner to fashion... especially prison fashions ... and TMZ has learned she's embracing her freedom by creating a whole new glam look for herself.

After serving 17 months behind bars ... Portwood has freed herself from her harsh, mugshot makeup ... and is now showing off a post-prison makeover that gives her a softer, more sophisticated look.

Sources close to Amber tell us ... she's treated herself to a whole new set of clothes ... and a stylish new haircut.

But the biggest change ... they say ... she no longer uses homemade, prison-style hairspray (which is often made from Jolly Rancher candies because it's sticky and provides excellent hold).

So, the good news -- she looks great.
The bad news -- her hair no longer tastes like grape.

Stop us if this one sounds familiar -- one of the people from the ex-MTV show "Buckwild" was arrested this morning in West Virginia ... this time for a DUI.

Anna Davis -- who the show described as a "true wild child" -- was busted early Saturday morning for aggravated DUI.

It's unclear at this point why the DUI charges were elevated since a whole slew of things could have caused it ... but the same thing happened to her co-star Bluefoot earlier this year when he had a BAC higher than .15.

Anna was released hours later on a $1k pr bond -- meaning she didn't have to pay ... just promise to show up in court.

Hollywood celebrities are abandoning the Lakers in droves ... and they're defecting to the rival L.A. Clippers ... so says MTV star Chris "Drama" Pfaff.

Pfaff -- who stars on a slew of MTV shows including "Fantasy Factory" and "Ridiculousness" -- was out in NYC yesterday when he admitted he's hitching a ride on the Clippers bandwagon.

"Clippers games used to be empty," Drama said ... but that was before Blake Griffin, CP3 and company began dominating.

Now, according to Pfaff, Lob City games are packed with celebrities and floor seats are nearly impossible to lock up.

Miley Cyrus traded twerking for toking at the EMAs -- the European version of MTV's VMAs -- puffing a fat joint on live TV Sunday night.

Cyrus performed twice during the show without sparking any controversy -- but while accepting the award for Best Video she shocked everyone by lighting up.

The awards were in Amsterdam, so she probably won't get in trouble, and Miley took full advantage ... while wearing a onesie and fur coat.

Guess marijuana isn't the only thing they're lax about over there.

When the EMAs aired in the U.S. ... Miley's joint smoking was edited out.

Pauly D's baby mama Amanda Markert doesn't deserve ANY custody of their child -- so says the father of her first kid, who thinks Pauly couldn't possibly be a worse parent than Amanda already is.

Lance Gerbino is obviously biased, but he's still got a lot to say -- telling TMZ, Amanda has done nothing but spew huge, wretched lies ever since they met.

Get this ... Lance claims a month before he knocked up Amanda she told him she had cancer and couldn't get pregnant. Further, Lance says when she did get pregnant ... Amanda left him in the dark about whether he was the daddy.

Lance says Amanda's now doing to Pauly what she did to him -- lying and playing games -- and that's why he believes Pauly should get full custody of Amabella.

Amanda declined to comment ... but we spoke with a close relative of hers who told us Lance is full of BS and called him "a freaking, druggie liar."

Pauly D has his own reservations about Gerbino ... one reason Pauly wants full custody of Amabella is because there's a felony drug arrest warrant out for Gerbino, and he doesn't want his baby anywhere near the guy.

Amber Portwood may be hanging out at a Panera Bread with her ex ... but that doesn't mean they're bangin' again ... this according to Amber and her baby daddy.

Amber and Gary Shirley made it clear outside the tasty food chain in Indiana today ... telling a photog they have no plans to get back together following her exit from prison this week.

As you may recall -- Gary and Amber had an extremely volatile relationship ... Back in '10 Amber was arrested for attacking Gary while MTV cameras were filming for "Teen Mom."

It was a whole thing.

For now, it seems the two are simply trying to get along for the sake of their kid ... but in case that doesn't work out -- hopefully Gary's learned to duck.

Pauly D will meet his 5-month-old baby for the first time today ... TMZ has learned.

We've learned the MTV star and his baby mama Amanda Markert have hammered out a temporary truce in their ongoing custody battle -- and Amanda has agreed to let Pauly meet their daughter Amabella.

Sources close to Amanda tell TMZ ... the meeting will take place at a neutral location somewhere near Amanda's home in New Jersey sometime in the next few hours.

It's a huge step for the parents -- who've hated each other's guts ever since the baby was conceived during a drunken night in Vegas back in 2012. Amabella was born back in May.

Pauly is fighting Markert for full custody of the little girl ... accusing Amanda of being a horrible mom who's using the baby as leverage for fame and to get money from him.

Markert says Pauly's interest in his daughter is all for show and is not real.

A rep for Pauly D had no comment.

Good to see they've put their differences aside ... at least for now.
