We broke the story ... Arenas was pulled over by the California Highway Patrol on June 27 for speeding ... and during the bust, cops say they found more than 100 pounds of fireworks.

Arenas was arrested -- and now, we've learned he's been charged with misdemeanor possession of dangerous fireworks without a permit.

Law enforcement tells TMZ ... because he had more than 100 pounds of bang bang, he faces up to 1 year in county jail and up to $10,000 in fines.

TMZ cameras were rolling during the bust -- as the LAPD bomb squad (carefully) removed the explosives from Gilbert's Ford truck.

Arenas is due in court for the matter next month.

Chris Brown took his bad-neighbor ways on vacation ... throwing a huge house party inside his rented Hawaiian mansion ... and pissing off a slew of neighbors in the process.

CB was in the Aloha state last week for a gig -- plus some graffiti fun -- and rented a sick pad in Honolulu. Check out the pics ... we're talkin' 5,100 square feet, pool and spa for $2,450 per night.

But CB didn't start out the best tenant ... sources connected to the situation tell us the first night Chris was in town he threw a giant shindig -- and neighbors were so pissed they called the owner of the house to complain.

The landlord took note, but didn't give Chris the boot. Did we mention the $2,450/night? We're told Chris and his entourage were at the house for a week and there were no further incidents.

As we reported, right after Chris got back from Hawaii ... his L.A. neighbors also complained about noise, but they called cops.

Dina Lohan may not have encountered 15 men on a dead man's chest at a Labor Day party, but it sure looks like she found that bottle of rum.

Dina, who played Tennille to a very eccentric Captain -- millionaire Sir Ivan Wilzig -- partied Sunday at Ivan's estate ... which people call the Playboy Mansion of the East Coast.

Several party-goers tell TMZ ... Dina went full bore, slurring her speech and at times zoning out, as she bragged that Oprah was interviewing her today for the Lindsay Lohan docu-soap.

We're told Dina was telling people at the party -- billed as "Sailors and Sinner Soiree" -- she was a good mother. She also said there was nothing ever wrong with Lindsay.

Now we know why things have been so quiet in Calabasas ... turns out, Justin Bieber's been on vacation with his pal Lil Za in the Bahamas... where they splashed around with an entire shiver of sharks and TMZ has the pics.

Fun Fact -- a group of sharks is called a "shiver" ... like a "murder" of crows or a "pod" of whales. Weird, right?

Anyway, Bieb and Za stripped down to their swim suits (Za appeared to be in his undies) and played in the turquoise water at the Staniel Cay Yacht Club ... where they hung out with some local Nurse sharks.

Don't worry ... there was no real danger -- while Nurse sharks can grow up to 14ft and weigh over 700 lbs, they generally don't attack humans ...

... unlike some other people we know.

Justin Bieber is wise enough to know when a gift needs givin' ... but he didn't have a box -- so he covered his junk with a guitar and jammed out a naked serenade for one lucky lady fan -- HIS GRANDMA!

TMZ has obtained photos of a completely nude Biebs strumming away on his big wooden instrument ... at his grandmother's home in Toronto during Thanksgiving back in November 2012.

And why, you ask, did Bieber go ass naked for g-ma?

Our sources tell us JB had been staying at his granny's house during the holiday ... and slept in a little too late on Thanksgiving morning.

Bieber finally woke up after hearing family and friends stirring around the house -- so he thought he'd prank 'em ... by grabbing his guitar and playing a naked set a la Jenny from "Forrest Gump" ('memba that?).

We're told birthday-suited Bieber went right up to his grandma and started belting out some impromptu lyrics ... like, "I Loooove you grandmaaaa ... how are youuuu ... helloooo grandma."

We're told G thought it was pretty funny -- and everyone in the home was cracking up -- but granny begged the pop star to get back in his room to put some damn clothes on, stat.

Thanksgiving -- they go balls out.

Lindsay Lohan has booked a one-way ticket to Europe ... set to depart as soon as she finishes rehab ... because everyone knows an overseas vacation is the best way to keep your nose clean.

Sources close to LiLo tell TMZ ... after her 90-day-court-ordered rehab finishes up she'll head to London for some R&R ... as the first stop on a European adventure.

We're told a gal pal of LiLo offered to take her as a gift for a "job well done in rehab". And since LiLo has some time before her OWN docu-series begins filming she jumped at the opportunity.

Our sources say she booked a one-way ticket and has no return date set (yet), but hopefully it's before she's scheduled to film.

Lindsay believes the trip will give her some privacy during her post-rehab days.

Plus, it's Europe ... what could go wrong?

So much for Selena Gomez being a good influence on Justin Bieber ... TMZ has obtained a photo of the underage singer boozing at a 4th of July party in L.A. -- and Selena just stood by and watched.

The photo was snapped at a Hollywood Hills house -- where the drinking age is still 21 -- and as you can see, Bieber is cradling a beer bottle (Dos Equis to be exact) ... squishing his crotch against Selena.

As we first reported, Selena gave Bieber another shot ... reuniting with him on the condition he clean up his act, and cut the antics -- pot smoking, speeding and bucket peeing -- with his buddies.

Apparently, 20-year-old Selena -- like almost every single college-aged kid -- is still cool with underage drinking though.

As for his taste in brew -- Justin Bieber doesn't always drink beer, but when he does ... he prefers to wear shorts made out of salvaged traffic cones.

Stay thirsty my friends.

WARNING: Never pass out drunk at a Paris Hilton party ... because her immature friends will dress you up in embarrassing clothes and then take photos of you.

The above pic was snapped at Paris' 4th of July bash in Malibu ... and as you can see, some poor schmuck obviously had a little too much to drink and fell asleep on a beach chair.

Thankfully, Paris and her friends let him snooze peacefully until he woke up. Just kidding, they dressed him up in a bikini top and gave him a purse and sunglasses. Then took photos.

As far as we know, no markers were involved ... those are this guy's actual tattoos ... but still, HILARIOUS.

Except not really.

As most people celebrate Independence Day weekend with a bar-b-que, ball game and some fireworks -- we'd like celebrate by paying homage to an often overlooked staple in this great nation.

With great anticipation we present Nicolas Cage... our "National Treasure."

For everyone currently eating themselves into a hot dog coma at their 4th of July barbecues, don't feel too bad -- competitive eater Joey Chestnut just downed 69 FRANKS at the famous Nathan's Hot Dog Eating Competition on Coney Island ... a new personal record.

Chestnut won the competition last year with 62 dogs, but this year he went above and beyond ... taking home the $10,000 grand prize and a mustard-yellow championship belt. Chestnut's previous personal best was 68 hot dogs.

He obliterated the competition too ... the 2nd place winner Matt Stonie only ate 51 hot dogs.

As for the women, Sonya "Black Widow" Thomas came in first with 37 hot dogs ... pretty damn scary.

Heidi Klum just posted this on Twitter ... and we have TWO fun facts:

1) Klum was born in Germany but obtained her American citizenship in 2008.
2) Who cares? She's in a bikini.

Check out which stars felt sweet freedom ... from their proverbial ball and chains ... over the last year and are celebrating their independence this 4th of July as single stars!

We've gone ahead and swapped the faces of some of Hollywood's elite with their loving patriarchs.
