Bohan Involved in Altercation Before His Arrest

BMX star Corey Bohan might have gotten off easy the night he was arrested -- because before he was popped for public intoxication, he was involved in a fight ... this according to law enforcement.

As TMZ first reported, Bohan (who sometimes dates Audrina Patridge) was busted on the misdemeanor charge early Friday morning.

But according to police, Bohan was first discovered by cops in the middle of a "physical altercation" in which he was allegedly the aggressor. However, cops say no one wanted to press charges for assault -- but because Bohan was showing signs of intoxication, "he was arrested for the safety of himself and others."

Police say he spent a few hours in jail and was released without incident ... once he sobered up.

Christina Aguilera: It's Hard Under the Microscope

Two weeks after being jailed for public intoxication (beau Matthew Rutler was charged with a DUI the same night), Christina Aguilera was in a cheerful mood while promoting her new show, The Voice, in L.A. Tuesday.

As son Max, 2, snuck Oreo cookies from the snack table, the singer, who will act as judge and mentor for the NBC singing competition, talked openly about the pitfalls of fame. "We're only able to be seen through the microscope of the media and what people gossip about," Aguilera, 30, told Us Magazine during her first public appearance since the headline grabbing arrest.

Yet the singer, whose recent booze-fueled outings have raised eyebrows, didn't let anything dampen her mood.

She yukked it up with fellow judge Adam Levine and played with son Max throughout the interview. Added Aguilera, "You take the good with the bad. It's by telling our stories, sharing our experiences and really giving a first hand look at us as human beings [that shows] who we really are apart from what we seem to be."

A lesson she's eager to pass on to the aspiring superstars on the show. "I am ready to share it all so I'm really excited," she gushed. "I hope we can find the next biggest thing. But I'm not looking for vocal acrobatics. I really sincerely want to be moved by raw talent."

Though, don't be mistaken, this isn't anything like those other singing shows, insists the star. "The Voice isn't about tearing people down," said Aguilera. "I want to bring people up. I want to empower them and give them all the tools I had. I love that I get to be apart of that."

Spencer Pratt -- I Was Arrested in Costa Rica

We're not vouching for Spencer Pratt, but his people tell TMZ Spencer was busted at an airport in Costa Rica for illegal possession of a firearm.

As the story goes ... Spencer was on his way out of the country when he was busted for felony possession. We're told he was booked and processed at a local jail and later released after turning over the weapons and signing a confession with the DA. Yes, we're skeptical, too.

So far, we haven't been able to confirm any of this. But we do have this bizarre statement from Spencer himself:

"As part of my spiritual cleansing I've spent the last week living alone in the jungle, reflecting on my past transgressions, and working to become a better person. I had to live off the land, and hunt to survive. As I departed the country this morning to continue my spiritual journey, I mistakenly brought my hunting weapons to the airport. It was an honest mistake, and they sent me on my way. On an unrelated note, I'm not allowed in the country anymore -- but that's because of the chicken incident."

UPDATE: As it turns out, Spencer Pratt was in fact arrested in Costa Rica yesterday. He was cited and released.

We've gotten our look at an arresting document from Costa Rica -- and even though it's in Spanish, it does have his name on it and includes words like "guilty," "charged" and "prosecution."

Heidi's name is in there to, listed as his spouse.
