Nickelodeon

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.

Nickelodeon is brainwashing your kids to think Italians are all bootlegging mafiosos and it MUST be stopped -- so says a pissed off Italian-American advocacy group, demanding parents BOYCOTT Nick's new flick.

The Italian-American One Voice Coalition -- a major national org. fighting against negative Italian-American stereotypes -- is peeved over the TV movie, "Nicky Deuce" ... set to bow on May 27th.

FYI :The flick is about a dorky Italian-American teenager who transforms himself into a mobster (to be cool, duh) ... just like his Italian-American uncle, who has mafia ties. Like "The Sopranos" with kids.

But One Voice tells TMZ ... this "trash television" is an affront to their culture, meant to "brainwash a new generation with an insidious and hurtful stereotype of Italian Americans."

"It is beyond reprehensible that Nickelodeon would so grossly abdicate any semblance of corporate responsibility and target young children with a biased, stereotypical movie."

They add, "We are appealing to all parents to not have their children watch this garbage."

Now here's the trailer. You decide ...

Nickelodeon star Drake Bell just took a beating in court -- because the actor/singer has been ordered to cough up $42,787 to Selena Gomez' music producer ... for crappy songs Bell allegedly never paid for.

TMZ broke the story ... producer John Fields -- who's produced songs for Selena, Jimmy Eat World, and the Jonas Brothers -- sued Bell for $36,000, claiming Bell commissioned 9 songs from Fields for his new album ... but only paid for 5.

Fields claimed Bell agreed to pay $9,000 per song -- and since Bell failed to pay for 4 of them ... he sued for the outstanding balance of $36k.

Now, Fields is getting all that and more -- because a judge has issued a default judgment against Drake for failing to respond to the lawsuit.

According to the court docs, Drake's been ordered to pay the full amount plus interest and attorneys' fees -- totaling $42,787.

Don't count on ever seeing the "Kenan and Kel" reunion you always hoped for -- because Kel Mitchell tells TMZ, Kenan's dropped him like a hot potato ... and is actively avoiding him.

Kenan Thompson -- who starred with Kel in a million different Nickelodeon projects back in the day -- is currently developing a new comedy pilot with NBC, so we reached out to Kel to see if he'd be making a cameo.

BUT OUR DREAMS WERE DASHED TO PIECES.

Kel tells TMZ, “The truth is Kenan does not want to be seen with me in any form of media, or even have my name mentioned around him.”

Kel says he nearly reunited with Kenan for an interview with a popular magazine but Kenan pulled out at the last minute ... and he thinks it's because Kenan's still trying to separate himself from his old co-star.

But Kel's not bitter, explaining, “I have not been upset about this. I respect his choice of wanting to make a name for himself solo.”

“There is no bad blood on my side, I’m not declining a reunion, I know the fans love the show and would love to see some type of appearance with us … I just don’t see that ever happening because of how he really feels.”

We reached out to Kenan's camp multiple times -- but our calls and emails were not returned.

President Obama's peeps say Mitt Romney is gonna be sorry for blowing off a bunch of kids who participated in the Nickelodeon show, "Kids Pick the President."

The premise of the show -- kids submit questions to each candidate and based on the answers they make their pick for leader of the free world.

Obama answered the kids' questions, but Romney said he didn't have the time.

Deputy National Press Secretary Adam Fetcher tells TMZ, "It's no surprise Romney decided to play hookey. Kids demand details, and I'm sure they want some answers on why Romney could increase their class sizes, eliminate their teacher's jobs, raise taxes on their families and slash funding for Big Bird."

"Big Time Rush" star Stephen Kramer Glickman says he got royally screwed on "Cupcake Wars" as a guest judge ... because the cupcakes he reviewed were TOTALLY GROSS.

Our photog caught up to the Nickelodeon star in Hollywood Friday night and he told us that being a celebrity judge on the Food Network show about AMAZING cupcakes -- was anything but.

Not only did he say the cupcakes were disgusting, he says he informed producers of a very particular food he absolutely could NOT eat. But come show time ... that's EXACTLY what they gave him.

Rottman, who starred in "Gigantic" but may be even more famous for dating Victoria Justice, jumped the curb as he was driving in Hollywood. His bad luck ... cops saw it all, pulled him over and then
smelled a strong odor of alcohol ... so say our law enforcement sources.

After giving Rottman a field sobriety test, they arrested him on suspicion of DUI.

We're told Rottman blew a .19 ... well over twice the legal limit.

He was taken to jail, booked and released a few hours later without having to post bail.
