Richie Sambora has walked away from the current Bon Jovi world tour because of "personal issues," the band said.

Although many assumed that "issues" was a code word for substance abuse problems, which Sambora has had in the past, TMZ claims this is not the case. The website reported it's just a matter that Sambora has had enough of Jon Bon Jovi.

Well, who could blame him? A guy names his band after himself, he's probably pretty intolerable.

Sources directly connected to the band supposedly told TMZ tensions between the two have been running high for years, and things have finally erupted. One source said "It's a classic Jagger/Richards blowup."

Uh ... yeah. I think that's about the only way anyone could ever compare Bon Jovi/Sambora to Jagger/Richards.

TMZ's sources say Bon Jovi constantly belittles Sambora. And they're also fighting over money.

Sambora didn't show up at the band's show in Calgary on Tuesday night. He posted on the Bon Jovi website that he was pulling out because of "personal issues."

Bon Jovi told the audience ,"I had two choices: pack up and go home or give you everything I got ... Richie Sambora won't be performing for a while. If there's ever a night I need you, it's tonight, Calgary!"

Bon Jovi is scheduled to perform in San Jose on April 25 at HP Pavilion. As of late Wednesday afternoon, there was no word on what the band would do to replace Sambora.

Sambora has been spending time with his daughter. TMZ said the pair were on vacation in Hawaii last week.

MEN WHO PLOTTED TO KILL JOSS STONE CONVICTED: Two men have been convicted of plotting to kill singer Joss Stone.

Kevin Liverpool, 35, received life imprisonment with a minimum term of 10 years and eight months, while the sentencing of 32-year-old Junior Bradshaw was delayed pending psychiatric reports, according to the BBC. It took a jury just four hours to made its decision Wednesday, at the Exeter Crown Court in London. Liverpool and Bradshaw were arrested in June 2011 near Stone's home in Devon, after neighbors became suspicious and called police. They possessed a sword, hammer, knives, gloves, and black bags.

What ... no chain saws?

Prosecutors said the men planned to decapitate the singer and dump her body into a river.

I don't think I want to be famous anymore.

Stone's mother, Wendy Joseph, told reporters outside the courthouse, "Joss would like to thank everyone for their support and all their good wishes. The whole family is relieved the trial is over and these men are no longer in a position to cause harm to anyone."

'GLEE' STAR PREGNANT: "Glee" star Heather Morris is pregnant with her first child.

A source close to the 26-year-old actress told Us Weekly. "She's a little more than three months along and starting to show." The dad-to-be is Morris' longtime boyfriend Taylor Hubbell, whom she met in high school.

"It was totally unexpected, but they are incredibly happy and excited," the source said Us.

Morris, who plays ditsy cheerleader Brittany on the FOX show, has long said she wants a family with Hubbell, even if it means shutting down her career.

"I want to marry Taylor and have kids with him," Morris told Fitness magazine in 2011. "I love acting, but if it affects my relationship, then I won't continue."

A second source told Us the pair has no plans to get married yet, though "I see it in their future."

AMANDA BYNES MISSES COURT: Amanda Bynes missed her court date on Monday in Southern California.

To be fair, Mondays are optimum days to spend smoking pot, driving rental cars without a license and sending bizarre tweets.

E! News reported the actress missed a hearing on her misdemeanor case for driving with a suspended license because she hasn't given her lawyer the signed papers for the plea deal they worked on.

Byne's attorney Richard Hutton was advised that his client would only be granted one more continuance on the case.

Burbank District Attorney Denny Wei said in order for the court to accept a plea deal the defendant must fill, notarize and send out a few forms waiving certain rights.

That sounds like a lot of work.

E! said that could be happening, as a now redheaded Bynes was spotted Tuesday running around New York City with a FedEx envelope.

Judge Margaret Oldendorf told Hutton she expected to wrap up the case promptly as it's been pending since September, when Bynes was charged for driving with a suspended license. Bynes pleaded not guilty.

CLARK GABLE'S SON ARRESTED: Clark Gable's son Jon Clark Gable was arrested for suspicion of DUI on Tuesday in Malibu after supposedly fleeing the scene of an accident, then smashing into six parked cars.

Six? That has to be some sort of record.

Citing law enforcement sources, TMZ reported the 52-year-old is suspected of initially rear-ending another car on Pacific Coast Highway in Malibu. Then he allegedly fled that scene and crashed into just about every other car in Malibu.

He was arrested Monday afternoon by Sheriff's deputies. A source told TMZ "It appears alcohol and/or drugs were involved."
