Law enforcement sources tell TMZ Dr. Conrad Murray's baby mama will testify before the L.A. County Grand Jury tomorrow at 11:00 AM.

Nicole Alvarez, the mother of Dr. Murray's 7th child, has not been cooperative with LAPD detectives. We have already reported that we have heard Dr. Murray was living with Alvarez during the time he was supposedly staying with Jackson. Law enforcement sources tell us they believe Dr. Murray was living with Alvarez but have not been able to confirm it.

If Dr. Murray was regularly around Alvarez during that critical time, she may have information that could be highly relevant to the investigation.

The UFC fighter hit up the Key Club after his "Dancing" debut last night -- where he was caught knocking back a few drinks inside and macking on a busty blond, who he later left with.

Maybe she was helping him with his horizontal mambo.

Federleezy has packed on the pounds of late -- see Exhibit XXL above -- but he's on a mission to reduce the rolls. Earlier today, a TMZ employee watched Britney's ex saunter onto the Simi Valley, CA set of the VH1 weight-loss reality show.

As TMZ first reported, Bobby Brown, Nicole Eggert and Kevin's other baby-mama Shar Jackson will also join him in trimming the fat.

We've learned Plaxico Burress arrived at Rikers Island jail in New York at 1:20 PM ET, this according to Deputy Commissioner for NYC Dept. of Corrections Steve Morello.

We're told Plax's stay will be a short one -- he'll be shipped off tomorrow to his next destination ... Fishkill Correctional Facility.

While Plax is behind bars at Rikers, we're told he'll be staying in an individual cell -- meaning no cell mate -- which includes a mattress, sheet and blanket, drinking cup, faucet, toilet, toilet paper and soap.

Also, we're told Plax will shower separately because of his celebrity status -- so he can drop the soap all he wants.

Gina Gershon's former agents have just unleashed an extremely nasty attack on the actress -- claiming she "thumbed her nose" at the agency when they sent her the bill.

The Fortitude talent agency is suing Gershon because they claim they hooked the actress up with a sweet gig on Broadway but never got their 10% commission on the deal.

But the best part of the suit, filed today in L.A. County Superior Court, is how Fortitude unloads on Gershon's character -- saying the actress is a "user" who "chooses to forget about those people who help her in her career."

The agents claim Gina has made "several hundred thousand dollars" from the play ... but they haven't seen a penny.

They are suing for an undetermined amount.

Gina's people gave us this statement:

Tom Brady and Gisele Bundchen have been sued by a pair of photogs who claim the superstars' bodyguards shot at them after a wedding celebration in Costa Rica earlier this year.

The photogs claim they got proper clearance to take photos from a nearby property -- but one of Brady's security guards approached the snappers anyway and demanded a camera and memory cards.

One photog claims he "managed to run off and escape" but the other says he was "grabbed by the bodyguard, his arm twisted behind him and immobilized."

In the suit, filed today in federal court in NY, the photogs claim 5 other men joined in -- and refused to let the one captive snapper go.

Eventually, the photog claims he was allowed back into the SUV and allowed to pick up the other photog -- but security demanded the two drive up to the Bundchen residence for further discussions.

In the docs, the men claim they tried to speed away from the security team, and that's when, "the Brady/Bundchen bodyguards opened fire with pistols."

The men claim the bullets "shattered" the rear window of the SUV" and "narrowly missed striking the heads" of the two photogs.

The photogs claim Brady and Bundchen were negligent in hiring and training the security team -- and allowed the hired muscle to "discharge firearms with intent to kill or wound."

The photogs are seeking more than $1 million in damages.

Reps for both Tom and Gisele have yet to comment.

The New York Giants gave us the following statement:

"This has been a tragic, sad, disappointing situation from the beginning. Our concern has always been for Plax's welfare, and for his family, and that continues to be our overriding feeling."

Plaxico caught the Giants' game-winning touchdown in Superbowl XLII -- when they beat the undefeated New England Patriots.

Several people who worked with her on the movie "Labor Pains" -- which was shot last year -- tell TMZ they saw Nick Prugo hanging out on the set with Lindsay. One person who worked on the set estimates she saw them together at least 10 times.

Prugo -- who is 18 -- was arrested for cocaine possession last February. He pled guilty and was placed in a drug diversion program. He was also arrested last month for DUI.

We don't know if Prugo had been to Lindsay's house prior to the break-in.

No comment so far from Lindsay's camp.

Sources close to the situation tell us every member of Lamar's team got an invite to the "secret" wedding -- including Kobe Bryant. We're also told all of the Lakers coaches were invited to the event.

Legendary porn star Jenna Jameson is accused of stiffing her former lawyers -- and not in a good way.

In a lawsuit filed today in L.A. County Superior Court., Jameson's former divorce team -- Hersh, Mannis, and Bogen L.L.P. -- claims Jenna never forked over $72,312.36 for work dating back to 2006.

In the docs, the lawyers claim they were hired to rep Jenna in her nasty divorce from porn kingpin Jay Grdina -- but after they obeyed her every command ... Jenna left the lawyers high and dry when they demanded a check.

"Octomom: The Musical" has been playing sold out shows in L.A. since mid-June, packing in audiences tighter than 8 babies in one uterus. Though the play was only supposed to run for a month, it shows no sign of stopping -- and is now moving to a larger venue.

The PR director for the musical tells us after this Saturday's show, they're closing up shop at The Fake Gallery and moving to "accommodate the growing audience and demand for tickets." We're told the show will re-open in October -- the new venue has yet to be announced.

We contacted two of the ticket brokers for the show -- Goldstar and EventBrite -- who confirmed it ... demand has been as crazy as Nadya herself.

Don't go blaming the Khloe Kardashian-Lamar Odom whirlwind wedding on the bride -- TMZ has learned this whole thing was Lamar's idea.

Sources close to the situation tell us it was Odom who was putting the rush on the "I do" swapping because the Los Angeles Lakers star wants to tie the knot before his NBA season begins.

David Hasselhoff says he wasn't drunk yesterday -- he wasn't even drinking and yesterday's drama was all a misunderstanding over an ear problem.

As we first reported, paramedics went to Hasselhoff's home yesterday and took him to the hospital -- this, after his daughter Hayley called her mom and sounded an alarm. Pamela says she was told David had been drinking and one of her friends then called 911.

Hasselhoff's people tell us he was being treated by his family doctor for an ear infection and was taking Antivert. Hasselhoff was also taking Antabuse, which prevents alcoholics from drinking. The Hoff's camp says the combination of drugs messed up his equilibrium, he was feeling sick and wasn't able to reach his family doctor.

Team Hasselhoff says when paramedics arrived David decided to go to the hospital -- not because he was drinking but to help with the equilibrium problem.

Hasselhoff's people say he was released an hour after being treated at the hospital.

TMZ has learned David Hasselhoff was taken to the hospital Sunday night after his daughter sounded an alarm that he had been drinking to excess.

We've learned 17-year-old Hayley Hasselhoff -- who was at home with David -- called her mother Pamela, claiming David was extremely drunk. One of Pamela's friends called 911, paramedics arrived at the family's home in Encino and took him to the hospital.

We're told the hospital was supposed to release David Sunday night.

No comment yet from Hasselhoff's reps.

Sources connected with John Travolta tell TMZ the actor's testimony in the extortion trial over his son's death will focus on two issues -- John's interaction with a paramedic/defendant as they tried to save his son ... and John's emotional reaction to the alleged plot.

As we first reported, Travolta will travel to the Bahamas and take the stand this week in the trial of paramedic Tarino Lightbourne and former Senator Pleasant Bridgewater. The pair is accused of trying to extort $25 million from Travolta by threatening to go public with a document that could have relieved medical responders of liability. Ironically, the document had no relevance.

Sources say Travolta will testify about his interaction with paramedic Lightbourne, who tried to revive Jett Travolta after he suffered a massive seizure at the family's Bahamian vacation home.

We're told once the extortion demand was allegedly made, Travolta had no direct contact with any of the alleged extortionists. But sources say prosecutors will ask Travolta about his reaction once he learned of the plot just days after his son's death. This will almost certainly be the most dramatic and emotional part of the trial which could have enormous impact.

Our sources say Kelly Preston will not testify.

Merriman was at the club again this past Friday -- less than two weeks after a night of partying there led to an alleged altercation with reality queen Tila Tequila.

The San Diego D.A. decided there wasn't enough evidence to charge Merriman.
