Dem Franchize Boyz lost one of their own this weekend -- Gerald "Buddie" Tiller passed away from what appears to be cancer, according to the group itself.

DFB posted the sad news Sunday, writing on Instagram ... "R.I.P. Buddie you Will be Missed #demfranchizeboyz." Jermaine Dupri -- who signed the group to his So So Def label in 2005 and pretty much put them on with their smash hit "Lean wit It, Rock wit It" -- also spoke on Buddie's death, and seemed to suggest he'd died from cancer.

On his own IG page, the hip-hop mogul made reference to a line from Buddie's verse on 'LWIRWI,' writing ... "'They call me Doctor Doc I prescribe what a n**** need' #ripbuddy may your soul rest easy #demfranchiseboyz #f***cancer."

Other rappers offered up their condolences as well -- including Da Brat and fellow DFB member Parlae.

Dem Franchize Boyz are perhaps best known for their two hits, "Lean wit It, Rock wit It" and "I Think They Like Me," both of which appeared on their debut album "On Top of Our Game." They did a mash-up of 'Lean wit It' with Korn called "Coming Undone Wit It."

Kendrick Lamar may be small, but the man is mighty -- that much we can tell by the way he trains in the ring.

The Grammy-winning rapper has been getting his box on lately at a gym in Northridge, CA -- about 20 minutes north of L.A. -- and TMZ Sports got a hold of what appears to be the only footage of Kendrick in the ring doing his thing. This clip is from earlier this year.

Dude's from Compton, but it seems he's been looking to keep an even lower profile than usual ... 'cause we're told this specific facility is pretty dang discreet.

As for what Kendrick has been getting into inside, welp ... take a looksy for yourself. As it turns out, Kung Fu Kenny's got hands -- you can see him doing a vigorous round of focus mitt drills with a trainer ... and we gotta say, KL could go toe-to-toe with any Joe there.

We're told Kendrick went about four rounds of mitts on this outing -- and he looked sharp all the way through. It's unclear what he's training for -- maybe he's just keeping fit?

Either way, the MC is no stranger to combat in his art. During his "DAMN" tour, he embraced the martial arts aesthetic in a video that accompanied his set, and homeboy could move.

Whether it's boxing or kung fu fighting ... Kendrick has made major strides from the way he used to throw down (jokingly, of course).

Your favorite rapper's go-to spot for the freshest bling in NYC is probably gonna be closed for a sec ... 'cause the place got held up at gunpoint in the middle of the day.

The robbery went down Sunday afternoon at Avianne and Co. in Midtown Manhattan, when at least three guys who were posing as customers whipped out handguns and cleaned the place out. And, by cleaning 'em out, we mean making off with tons of high-valued goods.

Law enforcement sources tell TMZ ... the robbers bounded the employees with zip ties and then emptied out a safe and cleared out a good amount of their display cases. It's unclear how many jewelry pieces (or how much cash) they left with, but safe to say ... it's worth a lot.

Rappers like Blueface, Kodak Black, Big Sean, Offset and other Migos, Lil Pump, Lil Uzi Vert, Fetty Wap and a bunch of other famous folks have walked out with intricate custom pieces from this joint that are valued at tens (if not hundreds) of thousands of dollars.

We doubt Avianne and Co. would have such pricey products out in the display cases, but an authentic Cuban link chain from a store like this could run thousands of bucks alone.

Based on all that, it's likely the guys who pulled off the heist walked away with quite the bundle.

Ariana Grande is coming back to Manchester to spread love more than 2 years since her benefit concert following the bombings there -- now doing a show for Pride.

The pop star will be in Manchester Sunday, where a live concert is being put on ... this following two days of other festivities, including a parade. Ariana is set to take the stage in Sunday's lineup, which includes other artists like Pixie Lott, Tulisa and Becky Hill. It's unclear what time exactly she'll come on -- she's the headliner for Sunday, so probably late.

This will be the first time AG has stepped foot in the city since June 2017, when she hosted the One Love benefit concert a couple weeks after a bomber detonated a homemade device that sent a bunch of nails flying in the rotunda area of Manchester Arena.

Ariana's concert at the time was winding down, but at least 22 people were killed nonetheless ... with several others being injured. It caused a massive panic inside.

The free benefit concert she put on afterward, which was organized with the help of her manager, Scooter Braun, drew tons of people and raised a lot of cash, upwards of $3 million.

Ariana was joined by other music acts like Justin Bieber, Katy Perry, Coldplay, Black Eyed Peas and others -- which made for a really sweet moment in the city.

We'll be on the lookout for her performance. Stay tuned ...

The audience loved it.

Mark Zuckerberg's summer of Man vs. Wild 2019 is in full swing up in Lake Tahoe -- where he's now a boating captain ... with a little assistance from the crew, of course.

The Facebook founder and CEO was at one of his two new Tahoe waterfront estates Saturday -- properties he reportedly dropped around $60 mil for this past winter -- and Zuck was getting briefed on a new operating system ... it's called HowToSteerVessels 2.0™.

Eyewitnesses tell us Mark and some pals were being taught how to steer this boat, and that he even got behind the wheel at one point as it drifted away from the dock.

It must've been a successful outing, 'cause we're told Mark and co. had the boat out on the water for a few hours before returning to shore. Now, it's unclear if MZ owns this thing -- it's possible he's just learning how to drive on it and someone was doing him a favor.

Ya gotta imagine when he gets it down, he'll shell out for something a bit nicer -- dude's worth an estimated $66 billion, after all. He can afford to be among Tahoe's finest, no doubt

It's interesting too ... Mark's been getting in the water A LOT over the past year or so, including what look like some cool ventures there in Tahoe this summer as well. He posted a photo last month of him paddle boarding on the lake and taking in a gorgeous sunset.

Stipe Miocic stepped out of the Octagon as the big winner, and then stepped right into this club a week later an even bigger birthday boy.

The MMA fighter celebrated winning the heavyweight card at UFC 241 against Daniel Cormier last weekend by raging at Cleveland's Barley House Saturday night, where he was met with a massive bottle of Luc Belaire bubbly ... which he promptly started drinking.

Nothing says 4th-round TKO victory like champagne to the face.

The party served two purposes as it turns out -- Stipe was also celebrating his 37th birthday, which had just come around this past Monday. That's why you're seeing cake here too.

The pastry came courtesy of Colossal Cupcakes, and it ended weighing in at 20 lbs. of pure edible gold in the shape of a UFC trophy. Looks like Stipe was diggin' lickin' it.

The Cleveland native was joined by some good friends, including Browns player Myles Garrett, whose team has looked pretty solid this preseason, but lost on Thursday night.

Kanye West is in Dayton, Ohio right now, presiding over his Sunday Service to honor those who died and were injured during the mass shooting earlier this month.

The service is going down at the RiverScape MetoPark to a large crowd.

Kim Kardashian and at least 2 of their kids -- Saint and North West -- are on hand for the event. They were all dressed in white as they headed to the service. We don't know if Chicago made the trip. We're told Dave Chappelle and Chris Rock are also in attendance.

Chappelle eventually took the stage to tell the large crowd that even after going through a tough time -- including tornadoes, Klan rallies and shootings -- "we're still here and we're still strong. And the only way, but not the only way, but the BEST WAY that we can honor our fallen is by getting up better than we were before." He finishes by thanking Kanye for coming out and reminds him that he and Dayton have his back.

Chappelle is also in Dayton for an event later in the day ... The Gem City Shine, a benefit concert, again honoring the victims of the latest American massacre. We're told around 20,000 people are expected to attend.

Speaking of Dave, Kanye led a rendition of "Happy Birthday" to him Saturday night inside what appears to be a hotel lobby. Dave turned 46. BTW, Kanye didn't sing -- he led his choir in a melodic rendition of the Stevie Wonder version. Dave toasted the crowd with a brewski.

David and Victoria Beckham are flexing their British roots with some of the best company the UK has to offer -- Sir Elton John is onboard with the couple on the same yacht.

The Beckhams and their children are riding on a luxury yacht right now with the legendary singer, his husband David Furnish and their kids -- where they're all enjoying the steady waters in the South of France ... and diving in feet first when the mood strikes, it seems.

Well, Dave is anyway -- he was snapped holding hands with his daughter, Harper, and one of Elton's boys ... jumping off the side of the yacht into the ocean as a group.

Based on what we can see here, the wife had a little something for him when he came back up dripping wet. Yes, you can feel the love today with these two ... it's as strong as ever.

As for boat wear ... DB went with the classic shirtless look, Victoria rocked a sun dress and Elton was in a floral design getup ... rockin' his shades too, per usual. Looks like he kept Victoria company at one point while Dave was splashing around with the kiddos.

Chris Brown's adding a lil' Breezy to his family ... TMZ has learned.

CB and and his ex-girlfriend, Ammika Harris, are expecting their first child together, and sources in the know tell us ... it's a boy.

The child will be Ammika's first, and a half brother to Brown's 5-year-old daughter, Royalty, whom he shares with Nia Guzman.

We're told Chris and his baby mama -- who are no longer together -- are getting along well. She's happy with the way Chris is treating her ... financially, medically and emotionally.

News the former couple is having a child together broke in June, but fans had their suspicions as early as May 8 when Chris commented on one of Harris' photos, "BM BAD" ... the BM assumed to be code for "baby mama."

Turns out, they were right!!!

Sofia Richie had the 21st birthday just about any 21-year-old would want ... a Vegas blowout.

Sofia and a bunch of her friends partied hard at the XS nightclub on the Strip, and it looked like a blast.

Scott Disick was there, but took a back seat to the action as Sofia danced wildly with friends. She went onstage with The Chainsmokers and just kept dancing.

There was the obligatory cake -- in this case, 6 tiers.

Sofia got some pretty awesome presents earlier in the day. Scott presented her with an Aston Martin and a Range Rover. Yep, 2 whips. When the cars were safely garaged, they jetted off to Vegas. Kylie was waiting at the airport where they all boarded the private jet.

In case you lost track, Scott and Sofia have been dating for about 2 years. They seem super serious ... she even hangs out with his kids, and she and Kourtney clearly get along. They've even all gone on vacay together.

Taylor Swift tripled down in an interview that aired Sunday, saying she's determined to get her OG music back, one way or the other.

Taylor appeared on CBS' "Sunday Morning," and made it clear ... she's going to rerecord the songs that made her famous. As we reported, Taylor surrendered any claim to the masters for her 6 original albums. The masters are owned by Big Machine, and she went ballistic when she found out Scooter Braun bought the company for $300 million.

Taylor made it clear ... she had no idea Scooter -- with whom she has a big problem -- was going to plunk down the cash for BM. She says she learned about the sale when the news broke online.

Kim Kardashian has now joined Kanye West's in Ohio ... and they're doing cheesecake for dinner.

Kim and Kanye were spotted leaving a Cheesecake Factory restaurant Saturday evening in Beavercreek, OH -- a city about 15 minutes outside of Dayton -- where they were ushered into a waiting SUV with security nearby.

We're told their son Saint, and daughter North, were with them for the hour-long dinner, which got started 6 PM. No word on what they chowed down on, but it's Cheesecake ... they got a lot of options (no specials though, apparently).

Anyway, Kim and Kanye definitely weren't trying to stay on the down low -- check out our video. You see them interacting with the crowd outside ... from a safe distance, of course. Kim said hi to some fans, and Ye flashed a peace sign.

Kim's appearance here comes a day after Kanye was seen roaming the streets of Dayton with other family members, including what looked like some of his kids.

Disney's new Tramp, in the upcoming live-action remake of "Lady and the Tramp," didn't slum it for too long before catching his big break ... we've learned the pup went from kill shelter to shelter before becoming a huge movie star.

Monte, the 2-year-old terrier mix had a rough start to life. He was on the verge of being euthanized at a kill shelter before the folks at HALO Animal Rescue in Phoenix scooped him up, saving him from death.

So, now's the terrier's big break ... Mark Forbes, the animal trainer for "Lady and the Tramp," was on the hunt for a scruffy canine, and Monte must have worked his magic at HALO because the trainer saw potential ... a potential movie star!!!

Forbes adopted Monte -- after the pooch spent just 7 days at HALO -- trained him well, and Disney execs fell in love ... i.e., Monte nailed the audition.

Good on the folks at HALO, because they wanted to make sure Monte didn't become one of the has-beens that litter the streets of Hollywood. The org made Forbes promise Monte would become a family pet once filming was over.

Forbes agreed, and he now lives with the fam and even has a newborn baby and pet raccoon to keep him company.

Monte's making his film debut on the new Disney+ streaming service this November ... and HALO hopes his story will lead to more adoptions for dogs in shelters across the globe.

'Baywatch' hotties Donna D'Errico and Krista Allen got a super sweet offer -- $300,000 to fly to Dubai and make a quick speech -- but turned out to be too good to be true ... because it was courtesy of the same scammers who tried to rip off Dog The Bounty Hunter.

Here's the deal ... reps for Donna and Krista were contacted by people purporting to be from the office of Sheikh Mansour bin Zayed Al Nahyan -- the Deputy Prime Minister of United Arab Emirates -- offering the ladies a fat payday in exchange for speaking at an economic empowerment convention for small business owners in July and rubbing elbows with dignitaries.

Donna and Krista's people got contracts emailed to them with all the deets, and it looked legit on its face ... but once the women signed, things got super sketchy.

Organizers in "Dubai" said they had difficulty wiring funds to Donna and Krista and started asking for more personal information. Huge red flag. Another catch -- organizers were asking Donna and Krista to donate half of the funds back to the organization.

Donna and Krista slowly started putting the pieces together, feeling something was off ... and they eventually got cold feet.

Fortunately for them ... the 'Baywatch' babes never gave up their personal info, dodging a huge bullet ... just like Dog.
