Teen Mom

According to the police report obtained by TMZ, the officer was concerned about a couple arguing inside of a Silver Dodge parked near the police station around 1:30 AM ... so he approached the vehicle.

The officer says Gary introduced himself and Amber as the couple from "Teen Mom" -- and that's when the cop asked for some ID. The officer ran a check on Gary's license -- and it came back suspended, so he ordered Gary out of the car.

According to the report, "I placed Mr. Shirley in two sets of handcuffs due to his size." Gary was taken to a nearby jail and his bond was set at $3,000. He has since been released.

Gary's lawyer, Jeff Lockwood, tells us ... "I am not concerned about him being sentenced to a jail term. It's a traffic violation and Gary doesn't have a previous criminal history."

According to reports, Amber Portwood's baby daddy was arrested at 1:34 AM for "driving while suspended" -- a Class A misdemeanor.

Custody was awarded to baby daddy Gary Shirley instead -- after an Indiana judge decided he was a more suitable parent ... at least for the time being.

But it wasn't because Amber's an unfit mother -- according to court testimony today, Child Protective Services recommended that Gary have primary custody because of recent vandalism to Amber's house and car.

CPS was nervous about Amber's living conditions -- so both parties agreed it would be best for baby Leah to stay with Gary until further notice.

And they said it wouldn't last.

Jo Rivera -- who goes by the rap moniker N.I.C.K.B. -- has released a music video for his song, "Unthinkable Remix" ... in which he tries to seduce an older woman.

But not everyone is a fan of Jo's career -- his baby mama, Kailyn Lowery, tells us, "I think he has his priorities mixed up right now. He should be spending quality time with his son while he’s not working."

19-year-old Evans -- who's currently on probation stemming from a drug-related conviction -- was surrounded by beer and beer drinkers at Yaupon Pier in North Carolina Thursday.

Good news for Jenelle though -- prosecutors are giving her a chance to clear her record ... by performing 24 hours of community service, at which point the charge will be dropped.

Jenelle was arrested back in October with her boyfriend, after the pair allegedly broke into some abandoned North Carolina house to smoke pot ... and were busted with a bag of marijuana and a pipe.

Brittany Maggard claims Jenelle only got up the guts to fight Britany Truett -- the eventual ass-beat victim -- because Maggard, Maggard's sister, and their friend Nick had her back. Maggard says Nick had the video camera.

After the fight, Maggard claims she and Nick came up with the idea to sell the video -- and Jenelle not only thought it was a "good idea" ... but SHE called "someone she knows at a [photo] agency to purchase the video."

According to Maggard, they sold the vid for $5,000 -- and Jenelle wanted a bigger cut because, as she said, "You wouldn't get any money if I wasn't famous!"

Britany Truett -- whose bruises have healed -- left her attorney's office this morning in North Carolina, along with her baby daddy. They proclaimed, "there will be legal action" against both Evans and Brittany 'The Pusher" Maggard.

Brittany -- who is on probation for a separate assault case -- got on the wrong side of her probation officer, who found out about the "Teen Mom" fight first posted on TMZ. After Brittany's arrest this week, the Department of Corrections of North Carolina set the wheels in motion to have her popped for violating probation -- which requires her to obey all laws.

Brittany is bitter, telling TMZ it's not fair she's in more trouble than the other girls in the fight and all she did was push Jenelle. She says she's "terrified."

Brittany Maggard -- who's been charged with misdemeanor affray -- says yeah, she regrets instigating the fight alright, but only because she wishes she would have done it for a better friend.
