UFC prez Dana White tells TMZ Sports ... Brock Lesnar wants to RETURN to the Octogon ... and White says he'd LOVE to have him back.

Dana was in NYC today getting ready for UFC's Super Saturday ... and told us Brock's still bummed his fighting career ended short due to injury ... and says "he'd like to take another run" in the UFC.

The former UFC heavyweight champ left the world of MMA in 2011 ... after a string of losses that he chalked up to his battle with a potentially life threatening case of diverticulitis (a digestive disease).

Your mom's Zumba class just got HARDCORE ... 'cause TMZ Sports has learned, UFC face-smasher Mark Munoz is taking up dancercise -- and we dare you to crack a joke (at least to his face).

Munoz -- who's currently ranked #7 in UFC middleweights -- hit up the LA Fit Expo on Saturday ... where he fulfilled his New Year's Resolution of (that's right) learning Zumba.

And guess what -- Mark says he loved the class so much ... he's actually considering using some of the moves in his regular MMA workout routine.

50 Cent has SERIOUSLY upgraded his personal security team ... 'cause one of the guys watching his back is UFC Hall of Famer (and ex-WWE superstar) Ken Shamrock!!!!

49-year-old Shamrock was spotted on the rapper's personal protection detail at the CES convection in Las Vegas yesterday ... and afterward, Ken confirmed he's now working for a company that does private security for several "high-end clients," including Fiddy.

After the convention, Ken tweeted that it was a "pleasure" working for 50 ... and said the rapper is, "By far one of the classiest gents I have ever worked with."

As for Ken's fighting career -- he may not have given up on the ring entirely ... just last month, he appeared in a wrestling event in Costa Rica.

But for now, don't screw with Mr. Cent ... or you might end up in a nasty ankle lock.

Hours after retaining his championship belt and possibly ending Anderson Silva's career ... UFC Middleweight champ Chris Weidman continued his campaign of destruction -- by decimating a double bacon cheeseburger.

Weidman partied at Surrender nightclub -- washing down his burger with a cold Miller Lite.

UFC's other big winner Ronda Rousey also feasted in celebration ... she went with family and friends to Wolfgang Puck's restaurant at the MGM for her usual post fight chicken wings.

America!

Georges St-Pierre cut a $737k check to his former manager -- after the woman sued the UFC champ for screwing her out of her contract ... and according to court docs, she could still be in line for a MULTI-MILLION DOLLAR payday.

TMZ Sports has obtained documents filed in Clark County, NV which show GSP was sued by ex-manager Shari Spencer after the two parted ways in 2011.

According to another manager who worked with GSP, Georges' relationship with Shari ended "very badly."

Shari clearly felt she helped build GSP's career and therefore deserved a cut of his fight earnings and sponsorship cash.

The court docs show ... the judge agreed with Shari and ordered GSP to cut a check for $737,066.35 -- which the fighter paid back in April.

But there's more ... the judge also ordered GSP to pay Shari's management company the following:

-- 20% of future revenue on various UFC Pay-Per-View fights
-- 20% of royalties earned under a 2008 UFC merchandising contract
-- 5% of future revenues from sponsorships she apparently helped him earn (including Affliction and RUSHFit).

A source familiar with the case tells us ... Shari's final cut could be worth several million dollars.

GSP's had a rough year -- as we first reported, the UFC champ is already stressing out over his sick father and an unplanned pregnancy.

First order of business ... turn my bedroom door into a Gucci shrine!!!

We'd say it looks lame ... but Rampage is really strong.

UFC heavyweight champion Cain Velasquez didn't let a busted face stop him from celebrating his victory last night -- the guy partied hard, bandages and all.

Cain and his crew hit up a club called The Mark in Houston, TX following Cain's epic win over top contender Junior Dos Santos at UFC 166 -- and despite the injuries, Cain kept a smile on his face.

In case you missed it, it was an awesome match. Velasquez eventually won out with a brutal TKO in the 5th round, but not without taking some damage himself.

UFC newbie Andre "Touchy" Fili has a secret weapon for his debut fight tonight -- stained, old green underwear ... and the fighter is pretty confident it'll give him an edge.

Fili knows the underwear might turn some people off ... however Touchy's convinced they'll bring him luck -- since he wore them during his most intense amateur fights.

Sadly, Fili won't actually be wearing the crusty briefs -- they're too long for his new gear ... but Andre says they will hold down the fort in his hotel room during 166.

As for the drizzle stains ... he's had 'em a long time.

Bellator CEO Bjorn Rebney says he's not interested because, "Risks already exist for the courageous, world class fighters who enter the Bellator cage; without adding further unnecessary risks into the mix."

Sucks for Rousimar -- since a handful of former UFC stars have made the switch to Bellator like Rampage Jackson and Tito Ortiz ... who fight on Pay-Per-View later this month.

Bjorn adds, "Fighter safety is paramount to me and my team."

McGregor tweeted photos of he and "Nasty" Willie Roaf hitting up The Library Thursday night in Las Vegas ... and the no-touching policy obviously wasn't in effect.

Fun Fact: Willie's mom was the first black woman to serve on the Arkansas Supreme Court ... and his sister is an Episcopal Priest.

We've all seen athletes do regular push ups. And clapping push ups. And diamond push-ups ... but have you ever seen anyone do BACKFLIP PUSH-UPS?!

Meet UFC fighter Chad Mendes ... who showed off his acrobatic workout skills at a media event for his upcoming fight against Nik Lentz at "UFC on Fox 9" in December.

For good measure, Chad also knocks out a "clapping behind the back" push-up.

Last time we saw anyone pull off push-ups like these ... was right before we turned off "Don't Mess with the Zohan."

Jon Jones is no match for Wladimir Klitschko or his brother Vitali -- so claims Joe Rogan ... who tells us the UFC champ's goal to beat one of the Ukrainians is laughable.

Joe couldn't have been clearer before blowing out of  LAX ... Jones wouldn't stand a chance in the boxing ring with either Klitschko -- both world heavyweight boxing champs.

Rogan says Bones WOULD have a better chance in an MMA fight ... but one Klitschko would still have a serious edge.

UFC Hall of Famer Chuck Liddell fought an intense battle in L.A. this week -- no octagon ... just octonauts.

The Iceman waded through hoards of children at the Topanga Mall -- daughter in tow -- to check out "Octonauts! Live" ... a stage production based on the popular Disney show.

The kiddie crush was all smiles as they gazed at Captain Barnacle and Kwazii -- but by the look on Chuck's face, he just took one for the team.

Watch the show open and listen to the theme song ... you'll understand.

Jon Jones may have had his face bashed in at UFC 165 last night -- but that didn't stop the light-heavyweight champ from flashing his extremely swollen face for a photo after the fight.

Jones' opponent Alexander Gustafsson posted the gnarly pic this morning online -- showing a beat up moment of respect between the two fighters inside a Toronto hospital after the pay per view.

UFC badass Miesha Tate says she won't rest until she BREAKS Ronda Rousey's face ... telling TMZ she doesn't just wanna win when they fight -- she wants to knock Ronda's ass out cold.

Tate -- who's currently a coach on Fox Sports 1's "The Ultimate Fighter 18" -- was out in NYC yesterday when she told us how she plans to defeat Rousey when they face off at UFC 168 in December.

"I'm just going to smash her," Tate told us ... "I want her to wake up and see the ceiling and the headlights and me standing over here with the belt on already."

It ain't gonna be easy ... Rousey's undefeated in the world of MMA ... and she's pretty handy with the arm bar.

Still, Tate's confident -- telling us, "I would love nothing more than to break her jaw."

Here's some video of Tate in action -- she's a BEAST!!!

Soooo ... Joe Rogan works out.

The UFC announcer went shirt-off at the beach in Hawaii this weekend ... proving Carrot Top ain't the only comic who knows his way around the weight room.

Fun Fact -- Rogan also happens to be a black belt in Brazilian jiu-jitsu ... which is why we're immediately issuing the following apology for comparing him to Carrot Top.

Sorry Joe.
