Eight years after marrying Britney Spears for 55 hours in Vegas, Jason Alexander is in the best shape of his life.

The yoked 30-year-old is now training to be an MMA fighter and by the looks of it he definitely has the goods for it.

Unlike K-Fed, breaking up with Britney does the body good.

"Seinfeld" star Jason Alexander pulled a John Travolta and showed up to an event in L.A. this week  (left) with much longer locks than he had on his bald head just three months ago (right).

Not that there's anything wrong with that.

Britney Spears has just learned .... it pays to have a conservatorship, and pays VERY well.



TMZ has obtained legal documents in the conservatorship case, showing that in December 2008, the assets controlled by Britney's conservators totaled $2,826,362.68. 

Now get this ...TMZ has learned ... exactly one year later -- in December, 2009 -- the assets controlled by the conservators swelled to $27,500,000 ... almost a 10 fold increase in 1 year.

Most of the gains came from Britney's wildly successful Circus Tour.

As for the assets at the close of 2008, there's an interesting breakdown.   Britney's "furniture and equipment" was valued at $1,551,026.  Her jewelry, furs and antiques totaled $264,988.

Now the figures are deceiving.  The conservators only control a portion of Britney's total estate.  She has a lot of money and property in various trusts and other business entitites, which the conservators do not control.

Britney Spears just lashed out against her ex-husband Jason Alexander -- and both of the publications responsible for publishing a phone call allegedly featuring her voice -- advising them all to "Kiss my lily white southern Louisiana ass!"



As we previously reported, Britney claims the person on the tape is not her -- and her lawyer has already threatened legal action against everyone involved in its release.

A highly-respected audio expert tells TMZ ... Jason Alexander's recording of the woman he claims is Britney Spears "has been electronically stepped on."



Tom Owen of OWL Investigations, and Chairman of the Audio Engineering Society Standards Committee of Forensic Audio, tells TMZ, the tape was "doctored" to such a severe extent, there's no way to conduct a meaningful voice-recognition test.

Owen says the tape has been "stepped on at least 3 times." With noise reduction, equalization and removal of voice qualities such as natural timbre, sibilance and tonal qualities, it's impossible to determine whether Britney's voice is on the tape.

Owen says Britney has a "very vanilla voice" and that with manipulation it wouldn't be that difficult to make someone sound like her.

A certified audio expert who has analyzed the purported recordings of Britney Spears speaking to Jason Alexander tells TMZ ... he believes the female voice is not Britney.



Arlo West, who is a certified forensic audio expert, tells us, "In my opinion, it's not her voice in the recording."

West, who compared the recordings with a half dozen interviews Britney has done over the years, says "Listening to the phonetics, it doesn't appear to be authentic," adding, "the mannerisms in her voice just don't match up."

The audiotape reportedly featuring Britney Spears saying that she was beaten by her boyfriend is 100% FAKE -- this according to one of Britney's co-conservators.



TMZ spoke to Andrew Wallet who told us, "Every aspect of the story published by Star Magazine is completely and utterly false."

He continues, "Star Magazine was informed of the falsity of the story before it was published.  All the statements attributable to Jason Alexander [in the Star Magazine story] are completely fabricated."

Wallet continues, "The audio recording posted on RadarOnline is a fraud and it is NOT Britney.

The audio they are allegedly relying on between Britney and Jason Alexander is obviously fake and ridiculous -- it is NOT HER.

Jason Trawick has never abused her.

They have defamed Britney Spears and we will be taking appropriate legal action."

Britney Spears complained to her first husband that her current boyfriend beat her ... this according to Star magazine.


According to the mag, Jason Alexander secretly taped Britney when she called him on October 10, complaining about Jason Trawick.  Jason says Britney "...told me that he hit her so hard it gave her a black eye."  Alexander adds, "She said she couldn't even leave the house for a week because of the bruising."

In the secretly recorded tape, Jason says, "I thought he proposed to you or something at the beach."
The woman purported to be Britney responds, "Before or after he beat on me."

The tape also references Britney allegedly saying, "My dad has a shotgun and he's just waiting to use it."

Trawick could not be immediately reached for comment.

 

TMZ has obtained the 911 call made after "Seinfeld" star Jason Alexander was involved in a car vs. bike accident with a young boy in Los Angeles back in April.



The call was made by a woman who had just witnessed the accident -- she says a "nurse" had rushed to the scene to attend the injured boy.

According to the caller, Alexander was driving a Prius at the time of the incident.

As TMZ first reported, the 14-year-old on the bike only suffered a slight laceration on his head -- and law enforcement sources tell us Alexander "acted responsibly" after the crash ...staying with the boy until paramedics and police arrived on scene.

Jason Alexander might be the best celebrity to get into a car accident with -- because the "Seinfeld" star tells us he's kept in touch with the 14-year-old bike rider who crashed into him last month.


As TMZ first reported, Alexander was involved in a car vs. bike collision in L.A. back in April -- cops quickly determined that Jason was not at fault.

As for the kid's condition, the kid suffered minor lacerations -- but Alexander tells us the boy is now doing "absolutely fine."

UPDATE: Law enforcement sources tell TMZ Alexander was not "at fault" for the accident.

As for the condition of the kid, we're told he has a slight laceration on his head -- but he'll be OK.

TMZ has learned "Seinfeld" star Jason Alexander was involved in a car vs. bicycle collision in L.A. this morning -- but fortunately, no one suffered any major injuries.

Law enforcement sources tell us the bike rider is a 14-year-old boy who was on his way to school -- when he collided with Alexander's vehicle.

We're told the kid fell off his bike and suffered a few bumps and bruises. An ambulance arrived to the scene -- but the kid's parents decided they wanted to drive him to the hospital for evaluation.

We're told speed was not a factor in the collision -- neither were drugs or alcohol. Jason was not cited for the incident.

We're told Alexander "acted responsibly" after the crash -- and exchanged information with the kid's parents.

We spoke to Alexander's rep, who told us "Jason stayed with the cyclist until the paramedics and police arrived and all indications are that the injury was minor."
