MMA fighter Muhammed Lawal -- known as King Mo -- wants to kick some serious ass this summer when he joins TNA wrestling ... so much so he's reaching out to some MAJOR ring legends for advice.

The former Strikeforce champion tells TMZ ... as a lifelong wrestling supporter, he doesn't want to disappoint any fans when he steps into the ring. So in order to prepare ... he called wrestling stars Hulk Hogan and Sting for some pointers.

We're told Hulk and Sting imparted their wisdom by telling Mo "just to learn and have fun" with it.

For those unfamiliar with the world of wrestling ... Mo is breaking barriers by fighting with two different companies -- Bellator (which is MMA) and TNA Wrestling -- simultaneously in a joint deal.

Icing on the cake ... Mo tells us several other MMA fighters have reached out to him with interest in crossing over as well.

We smell a battle.

Brooke Hogan is following in her father's giant yellow footsteps ... TMZ has learned she just inked a deal to join the TNA Wrestling family.

TNA President Dixie Carter tells TMZ ... Brooke is NOT going to be a wrestler ... but rather an executive who will be tasked to develop female talent.

We're told Brooke's duties will help up and coming she-wrestlers develop their characters, help with backstage promos and even consult on entrance music.

Obviously, 24-year-old Brooke has been around the wrestling world her entire life ... and believes she can help improve the organization. It doesn't hurt that her father also works for TNA.

Carter tells us, "Brooke is such a great talent who's really sharp and will make a great addition to the TNA family."

Hulk Hogan is freaking OUT over screengrabs of his alleged sex tape that have leaked onto the Internet -- and now, the wrestling legend's taking legal action ... sending in his lawyer to clean up the XXX mess.

The black-and-white pics -- which appear to show a naked Hulk doing the nasty with an unidentified female -- surfaced on TheDirty.com last week ... and more pics followed.

But Hulk isn't taking the affront on his knees -- unlike a certain unidentified female -- in fact, his lawyer just fired off a cease and desist letter to TheDirty.com editor Nik Richie, demanding Nik take down the pics forthwith ... or face a lawsuit.

The lawyer writes, "As you know, should a sex tape or photographs of Mr. Bollea exist, they were taken without his consent and therefore the same would constitute a felony in the State of Florida."

We're told Nik and TheDirty.com have no plans to remove the pictures in question. Stay tuned ...

Count Linda Hogan among those who want to see Hulk Hogan's sex tape -- but get your mind out of the gutter ... it's because she thinks it will help her defense in Hulk's lawsuit against her. 

As TMZ first reported, a sex tape featuring the wrestling legend is being shopped to Vivid Entertainment ... a tape Hogan says was made without his knowledge. 

Sources close to Linda tell TMZ she'd like to get a look at the tape because she feels it could be a key piece of evidence in Hulk's defamation lawsuit against Linda. Hulk sued Linda last year ... claiming she was lying when, in her book, she alleged Hulk was abusive and cheated on her. 

We're told Linda would like to figure out when the tape was made because it could help her prove Hulk was a cheater. According to our sources, if Linda can figure out who has the tape, she'll attempt to subpoena them for her case.

Hulk told TMZ this week he has been faithful to his current wife Jennifer, so the tape is at least five years old.

The kingpin of porn has reached out to Hulk Hogan in an effort to entice him to change his mind about the sex tape that has surfaced featuring the famous wrestler.

Steven Hirsch from Vivid Entertainment has sent Hulk a letter, which touts his company's stable of stars who include Kim Kardashian, Kendra Wilkinson, Tommy Lee and Jimi Hendrix.

After we broke the story that Hulk is front and center in a videotaped sexual encounter with a mystery brunette, he was adamant that he had no idea he was being taped and he would go after the people behind the tape both civilly and criminally.

Hirsch tells Hulk in the letter ... he admires what Hulk has accomplished and then says he saw a "teaser" of the tape and believes there would be a "huge demand."

Huge or not ... Hulk and his lawyer could not have been clearer on TMZ Live yesterday ... they don't want that tape to see the light of day.

Hulk Hogan just can't seem to identify his female co-star in the sex tape that just surfaced -- telling TMZ, he banged so many chicks after he left his ex-wife ... the woman could be one of MANY possible conquests.

Hulk called in to TMZ Live moments ago ... claiming he went on a 4-month alcohol-fueled lady-screwing bender between the time when he left his ex-wife Linda ... and met his current wife Jennifer.

Hulk tells us, "During that time, I don't even remember people's names, much less girls."

Hulk says he hasn't had sex with another woman since meeting Jennifer 5 years ago -- so the tape has to be at least 5 years old.

Hulk still has no idea who's selling the tape or how that person acquired it -- but Hulk's lawyer says, "If anyone goes forward with this thing, we're gonna find 'em and we're gonna prosecute."

Hulk Hogan says the sex tape being shopped to porn companies was "secretly filmed" WITHOUT his permission ... and claims the footage is nothing less than an "outrageous invasion of privacy."

TMZ broke the story ... the grainy video which has already been shopped to Vivid Entertainment features Hulk and a mystery brunette. It's unclear when the tape was shot.

Now, Hulk's lawyer David Houston has released a statement ... saying, "Terry Bollea is appalled at the unauthorized release of a secretly filmed video."

He adds, "[Hulk] neither approved of the filming nor the release of the same.  It is clearly an outrageous invasion of privacy and breach of trust if it is genuine.  We will take all necessary steps to enforce both civil and criminal liability.”

A sex tape featuring legendary wrestler Hulk Hogan has surfaced -- and TMZ has learned, it's currently being shopped to a major porn studio.

We've seen a portion of the grainy footage -- featuring Hulk getting undressed and a naked, unidentified brunette lying on a bed. The woman is NOT his ex-wife Linda or his current wife Jennifer McDaniel.

In the clip, Hulk pulls his shirt off and brags to his companion, "I started to work out again." Hulk then runs his hands through his blonde hair like he always does.

The best part ... Hulk's thong-shaped tan line.

It's unclear when the tape was shot -- but Vivid honcho Steve Hirsch tells TMZ, he was approached with the tape very recently by a third party.

So far, no word on whether Hirsch or anyone else has made an offer to buy the tape.

Hulk did not have an immediate comment. 


Hulk says the tape was "secretly filmed" without his permission -- and now his lawyer's on the rampage ... claiming, "We will take all necessary steps to enforce both civil and criminal liability.”

Former WWE superstar Chyna is finally getting back in the ring ... taking on 9 dudes at the same time ... except it's for a porno movie.

TMZ has learned ... Chyna was totally serious about pursuing a XXX career ... and just wrapped up on a Royal Rumble-inspired flick in which she locks up with a bunch of dudes who all look like famous wrestlers ... including a wannabe Hulk Hogan, wannabe Triple H, wannabe Ric Flair and more.

Weird thing is ... Chyna and the REAL Triple H actually dated for a while before he married Stephanie McMahon back in 2003.

The WWE obviously has no affiliation with the Vivid Entertainment flick. We called the wrestling titans for comment, but haven't heard back yet.

Hulk Hogan's decision to shave that iconic handlebar mustache is a devastating blow to the world's collective upper lip. Condolences to the stache's loved ones -- aka ... everyone!

Angels will DIE if Hulk Hogan shaves his mustache ... so says the leader of a powerful mustache organization.

TMZ spoke with Dr. Aaron Perlut -- Chairman of the American Mustache Institute and self-professed doctor of "nuclear mustacheology" -- who says he's particularly upset with Hulk's plan to shave ... since he is "seen as a longtime leading figure in the sexually dynamic Mustached American community."

Perlut says, "Not only would the removal of his lower nose foliage cause angels in heaven to die and fall to earth -- as is written in biblical texts -- but it would send a poor message to young people of Mustached American descent who wish to embrace the Mustached American experience."

"We do hope that Mr. Hogan, for whom we have great reverence, reconsiders shaving his upper lip shading device as millions of those he has inspired would be greatly let down, leading to mass chaos and deep bouts of depression in the Mustached American community.”

Neither Hogan nor his mustache could be reached for comment.
