What happens when you fall off your bike in a gnarly motorcycle crash? YOU GET YOUR ASS BACK ON ... especially if you're "Big Time Rush" star
Logan Henderson.
TMZ has learned ... the Nickelodeon actor is back up on two wheels after a frightening crash in Hollywood back in December that he luckily escaped from with only scrapes and bruises.
Henderson's motorcycle was badly damaged in the wreck -- when he was cut off by another driver and thrown from his bike. But Henderson was determined to ride again ... and had the bike repaired.
The final bill -- $8,000 ... but luckily for Logan, we're told the other driver's insurance covered the cost.
After the repairs, Logan was so pumped to get back on his bike -- he rode it to set for the taping of the season 3 finale of "BTR" ... and don't worry, he made it there safely.

If
Justin Bieber continues to trust Lil Twist with his ultra-expensive cars, then he deserves what he gets, because TMZ has learned Twist had yet another mishap, and this one involves a hit and run.
We've learned Lil Twist was driving Justin's chromed-out Fisker Karma Tuesday, just after 6PM, when he crashed into cement poles protecting a wall at a San Fernando Valley liquor store ... damaging the poles and badly damaging the front-end of the car.
Sources tell us ... either Twist or one of his passengers told an eyewitness, "Do you know whose car this is? It's Justin Bieber's car."
We're told a few minutes later, a BMW roared up to the parking lot and the driver told Twist and the passengers, "Get all the pieces from the car [that fell] and put it in the car [the BMW]." After putting the Fisker parts in the BMW, the 3 men took off in the BMW, leaving the Fisker behind.
Sources say one of the 2 passengers was Chris Brown. His reps have not confirmed or denied.

FYI -- it's a crime to leave the scene of an accident that causes injury or property damage without exchanging info with the victim -- in this case the liquor store owner. We're told this was NOT done.
You'll recall ... Twist also caused
thousands of dollars worth of damage when he bottomed out Justin's Ferrari in the Four Seasons Hotel parking lot. And Twist was
speeding in Justin's Ferrari January 1st when he was stopped by the CHP. A photog died while taking pics of the scene.
Justin -- don't be an idiot. Cut him off.
8:17 PM PT... Chris Brown's people just got back to us and said he wasn't in the car and wasn't even in town the day of the crash.
The charges against
Paulina Rubio were so minor, Miami police didn't plan to take her to jail yesterday -- but according to the police report, the final factor in their decision ... Rubio told cops she had to get home to breastfeed her child.

According to the report, after Rubio got into a car accident, the first officer on scene instructed her to get out of her car and onto the sidewalk. Rubio refused to get out of the car, the report states, at one point cursing at the officer in Spanish.
Once the officer told Rubio she was under arrest, got her out of the car, and placed the handcuffs on her, Rubio screamed out, "Help! Help! I didn't do anything! Look what they're doing! Help! Abusers! You bunch of liars! Help!"
The report says Rubio continued to yell at the officers even from inside the patrol car. An hour later, according to the report, Rubio calmed down and apologized. The officer says he issued her a summons to appear in court, and didn't take her in to jail, because she claimed to have "an extenuating circumstance (she breast feeds her 6 month old child)."
As TMZ first reported, Rubio
was charged with disorderly conduct, obstruction of justice and refusal to obey a lawful command.
A rep for Rubio had no comment.
Paulina Rubio was arrested by police in Florida on Saturday afternoon after she got into it with cops following a small car accident -- but she was not taken into custody ... TMZ has learned.

Law enforcement sources tell TMZ ... Rubio was involved in an accident just blocks away from the ocean in Miami.
According to law enforcement, the accident was relatively minor -- and Rubio was not at fault -- but she got into some kind of argument with officers on scene and was subsequently arrested.
We're told she was busted for disorderly conduct, obstruction of justice and refusal to obey a lawful command -- but the charges were small enough that Rubio was not taken into custody. Instead, she was issued a summons to appear at a later date.
Calls to Rubio's rep were not immediately returned.
"
Real Housewives of Beverly Hills" star
Lisa Vanderpump tells TMZ she just got attacked by a lumber truck driver in Beverly Hills.

Lisa tells TMZ ... she was driving on Benedict Canyon Drive when some lumber from the truck in front of her fell off. Lisa tried to avoid the wood by attempting to quickly pass the truck, but she says the truck driver intentionally tried squeezing her to the curb.
Lisa says the truck actually attached to her Bentley, causing "serious damage."
And Lisa tells us, "I'm not feeling so good. I'm going to see a doctor."

Lisa's "Real Housewives" co-star
Kyle Richards showed up at the scene to help.

She says she's not going to file a police report.
After the accident, Lisa's husband
Ken Todd told us some great news ... their dog
Jiggy wasn't involved in the crash.
Tara Lipinski just scored a perfect 10 in her legal battle against a dude who claims the former Olympic gold-medalist wrecked his car and caused him "serious injuries" -- in fact, girl got off the hook scot-free.

The guy in question -- named
Bryan Fuller -- sued Lipinski for $7,500 in July, claiming she backed into him with her SUV while he was exiting an L.A. parking lot last year ... and as a result, he suffered "serious injuries to his neck, back, left shoulder, left arm" ... and the list goes on.
Dude claimed his medical bills totaled $2,279 after the incident -- not to mention "at least" $1,223.02 in damages to his vehicle -- but clearly the judge wasn't buying his case ... because when the gavel came down earlier this week, Mr. Fuller was awarded jack squat.
Lipinski has a history of sliding by.
Jesse James had a total breakdown during an off-road race in Primm, Nevada this weekend -- and sources who know nothing about cars have determined the whole thing is
Harvey Levin's fault.

As we
previously reported, James threw a HL decal on the side of his badass custom-built racer ... despite multiple warnings that Harvey has a
terrible history with cars.
So when the truck was set to make its official debut -- everything went to hell ... meaning the car broke down mid-race and never crossed the finish line.
He may be the size of a leprechaun ... but he's clearly no lucky charm.
A TV chef who barely survived
Gordon Ramsay's kitchen is once again lucky to be alive ... after he was involved in a nasty hit-and-run crash that left the cook seriously banged up.

TMZ spoke with
Chris Spradley -- one of the culinary competitors on Ramsay's upcoming show "
MasterChef" -- who tells us dude was driving home from the
House of Blues on the Sunset Strip last week when some dumbass in a minivan blew a stop sign ... and the two vehicles collided.
Spradley -- creator of a beer cheese soup that Chef Ramsay considers "
the most disgusting f**king soup I've ever tasted in my life" -- suffered injuries to his ribs and ankle ... but nothing life threatening.
Law enforcement sources tell us the four passengers in the other vehicle were all intoxicated -- and they claim the driver of the van fled the scene. So far, no arrests have been made.
LeAnn Rimes -- no stranger to ramming into things she's not supposed to -- was at it again today ... but this time the victim was an un-married golf cart.

According to witnesses at the scene, LeAnn was backing out of a parking spot at
The Commons shopping center today in Calabasas, CA when she collided with a security golf cart.

We're not sure who was at fault -- but we do know there were no injuries and the matter was taken care of privately.
Michael Phelps may not have been at fault for his car accident this week, but he wasn't exactly squeaky clean, either.
Phelps will be cited for driving with an expired license, which was from Michigan, the
NY Post is reporting. Phelps will have to appear before a judge, though no date has been set so far.
Phelps also admitted to police he had a beer about an hour before the crash. He was not given a Breathalyzer test on scene.
Phelps was involved in a two-car accident in Baltimore on Thursday. It was ruled the other driver ran a red light, causing the wreck.
Have you thought about telling your boss to shove it, selling off all your stuff, and hitting the open road with Paris and Nicole's Airstream trailer? Time to go!

That's right, the same 25-foot 2004 Airstream trailer that Paris nearly crashed in "The Simple Life" is up for sale on eBay. Paris put the ding in the rear panel ... long before she was
in the ding herself!
