Teen Mom

Britany Truett tells us the gnarly fight was over a boy -- aren't they all? -- who just happens to be Jenelle's ex, Kieffer. She says Kieffer made a pass at her when the three of them were hanging out and Jenelle was not pleased.

Britany says she was shocked that Jenelle got so angry, since they have been friends for seven years and Brit has no interest in Kieffer.

Britany claims she has a bruise on her eye, scratches on her face and a bite mark on her breast. She says she's spoken to Jenelle since the fight went down, but only through Facebook ... in messages she described as Jenelle "smack talking."

The Brunswick County District Attorney's Office tells us the matter is "under investigation" ... noting it is "working closely with the Brunswick County Sheriff's Department."

As we previously reported, Jenelle was caught on tape beating the crap out of another woman earlier this week.

19-year-old Jenelle is clearly the instigator -- spewing all sorts of nasty insults at a woman named Britany ... before the reality star suddenly socks the other woman in the face with a closed fist.

The two women tussle to the ground ... where Jenelle continues to pummel Britany ... even AFTER it's clear she can no longer defend herself.

With Britany bleeding from her face, one of Jenelle's scumbag friends pulls the reality star off the other woman ... while Janelle continues to drop verbal insults.

It's unclear why Jenelle wanted to fight Britany ... but sources connected to the incident claim it had something to do with Jenelle's boyfriend.

Evans is facing charges in North Carolina of injury to personal property -- for allegedly breaking her ex Kieffer Delp's iPhone -- and a charge of misdemeanor breaking and entering into the home of her ex-BFF Jaelanie Salas.

But when neither Delp nor Salas showed up in court ... the prosecution was granted a continuance. All sides are due back in court April 29.

Sources close to Kailyn tell TMZ, she "doesn't know what to believe" anymore -- because her baby dad Jonathan "Jo" Rivera continues to deny that he was ever arrested for "being under the influence of marijuana" ... despite reports to the contrary.

According to sources, Kailyn confronted Jo about the arrest and he insisted it didn't happen ... even though law enforcement sources confirmed to TMZ Jo was booked on the pot charge alongside his older brother Edward.

Kailyn and Jo currently share custody of their baby son Isaac ... but after Jo's arrest, we're told Kailyn is strongly considering a move toward full custody.

Gary's been working with Rodney Razor at Stay Fit 24 in Indiana. Gary is currently clocking in at 320 lbs, but Rodney says he'd like to see that down to 220.

We're told Gary's workout consists of intense cardio, including treadmill and elliptical exercises, and weight training -- or as it's known in the fitness community, "exercise."

Gary has been instructed to adhere to a low-carb diet, stressing a healthy breakfast and eating every 3-4 hours -- or as it's known in the health community, "a diet."

Gary's trainer tells us, "I definitely want to see him lose and I’ll do everything in my power to see that it happens, but it just takes commitment on his part."

With a trainer at his side, Big Daddy worked up a sweat at a gym in Indiana on Wednesday.

According to sources close to Gary, he's going all Jared with a Subway diet -- ordering foot-long grilled chicken sandwiches with water and apples ... and saving half for later.

We're told Gary also plans on cutting back on the bad stuff ... greasy fried foods, eating late, etc ... and stocking up on salads, fruits, and veggies.

Although the two arrived to the Indiana court separately -- the on-again off-again parents quickly joined forces after the judge modified the existing order ... finally allowing the couple to hang out as they please.

But as we first reported, there's a slight catch -- Amber and Gary still can't be in the same room with their daughter Leah ... unless they're trading custody.

But there's still one major catch -- TMZ has learned the judge is refusing to allow Gary and Amber to be around their daughter Leah at the same time.

We're told the three of them are only allowed to be in the same room while trading custody of Leah.

Amber still faces two felony counts of domestic battery, one felony count of neglect of a dependent, and one misdemeanor count of domestic battery for allegedly beating the crap out of Gary in front of Leah ... and MTV cameras.

According to a police report filed in Anderson, Indiana last week -- Amber called cops after receiving 24 calls from a blocked number between 11:56 PM on February 3 and 5:21 AM on February 4.

Amber claims she could recognize the voices as Gary and his friend Ashley Williamson.

Amber told police she could hear Ashley threatening to kick her ass during the calls -- and she also says Gary was repeatedly saying "sexually vulgar" things to her. Amber claims the comments were SO vulgar, she refused to be more specific when speaking to police.

Law enforcement sources tell us, Amber filed a police report around 5PM -- saying someone claiming to be Gary had been harassing her over the phone ... and wouldn't leave her alone.

But Gary insists it wasn't him -- in fact, when the alleged phone calls took place, he tells us, "My ass was sleeping."

Maci was out with her best friend in NY last night -- and explained, "I was on vacation and Bentley wasn't with me and I was having a beer."

She adds, "It's obviously something I don't do anymore because I've grown up since then."

No word on when exactly the alcohol-infused party pics were taken -- but thankfully, Maci doesn't look pregnant at the time.
