Travis Kelce might've forgotten his razor at home before heading to Florida ... 'cause the NFL superstar's offseason workouts are quite the hairy situation.

The Kansas City Chiefs tight end got in a sweat sesh with buddies Ross Travis and Kumar Ferguson in Florida on Tuesday ... and as he made his way to a luxurious black car, he elected to pop his top and towel off before getting in the whip.

Kelce -- who was wearing all-black sportswear for the occasion -- appeared exhausted after the workout ... and as he lifted his shirt, he put his back fur on full display.

Flutter kicks may get the chicks, but can you dive into these before-and-after shots and guess who owns this incredible celebrity transformation bod?!

Here are a few clues: He's a country music artist who grew up in the South. He's got three precious kiddos. If you can guess who he is, then you're getting "One Thing Right."

12:24 PM PT -- Mayweather Fitness co-founder and CEO, James Williams, one of the people who the letter was sent to, tells TMZ Sports the following ... "My team and I have consistently operated Mayweather Fitness with integrity and in full compliance with all applicable laws and regulations, and we look forward to that being clearly reflected through current proceedings."

"I’ve always had a great relationship with Floyd, and want to make clear that the letter is correct in stating that I oversee and am responsible for all operational aspects of the business. Floyd is not involved in the day-to-day operations."

"My focus remains on leading the company, supporting our partners, and continuing to build the brand."

Floyd Mayweather is sending a salvo at the many fitness clubs bearing his name ... warning Mayweather Fitness to shape up or face the consequences!

TMZ Sports obtained a letter, sent last week by TBE's attorneys, demanding that the franchised health clubs fix a laundry list of alleged issues, or they'll find themselves in court opposite Floyd.

Among the 50-0 fighter's beefs, Floyd says Mayweather Fitness + Boxing, with over 50 locations in the U.S., has allegedly failed to pay their employees wages, and the legendary boxer, who says he has no control over day-to-day operations, is paying the price.

"Mr. Mayweather has not participated in the management, operations, or strategic oversight of [Mayweather Fitness]. Despite his limited involvement as a brand ambassador, your organizations have continually and improperly exploited his name, image, and likeness for financial gain while simultaneously embroiling him in lawsuits and negative press."

Actor Neal McDonough is a few months shy of his 60th trip around the sun, but the Hollywood star just took on one of the most physical roles of his career, and he says he busted his ass getting in peak shape!

In the movie, "The Last Rodeo" -- hitting theaters May 23 -- McDonough plays a retired rodeo legend who is forced back onto a bull in a desperate attempt to make money for his family.

Bill Belichick is finally opening up on that viral beach yoga session he had with Jordon Hudson ... and he's making it clear, he enjoyed it!!

Bill didn't elaborate too much on how the exercises go with his 24-year-old boo -- but he told Crowder with a smile that he's simply "trying to stay young!"

Pete Davidson's flexing a lot more than his comedy muscles these days ... proving he's got real physical ones too -- looking ripped while grabbing some delivered groceries off his stoop.

The actor was spotted in New York City outside his place Friday morning ... wearing a small white tank top which showed off his buff arms -- a pretty clear sign he's been working out recently.

Also worth pointing out ... that tattoos that used to cover his arms are super faded now -- so, it looks like the laser removal is really working for him.

Sam Asghari gave fans a front-row seat to his workout with an eye-popping fitness video -- and LBR, this will have you questioning if the only thing getting a workout in is his muscles.

In an IG clip, shirtless Sam was fully locked into beast mode -- while fans were, ahem, equally fixated ... particularly on one standout asset that had some serious airtime during enthusiastic jumping rope.

Yup, you need to see the video for some serious bounce -- 'cause honestly, it speaks for itself. But just to drive it home one last time: Britney Spears’ ex? Yeah, he’s got the whole package, no question.

The former Univ. of Florida defensive lineman, who was just picked up by the Tampa Bay Buccaneers after going undrafted last month, has found a whole lot of success while up over 400 pounds ... playing in 51 games with the Gators over the last four years.

But, he told us that while being big has its pros ... he believes slimming down could make him a whole lot quicker in the NFL.

Lizzo's going sun's out, buns out at the beach this summer ... showing off her swimwear picks in a new IG video -- and, it's certainly going to be a cheeky few months.

The singer-songwriter shared a video hyping up her Yitty swimwear brand ... kicking it off by leaving little to the imagination in a hot pink bikini.

Lizzo says the bikini is her new uniform ... talking up her tight top and bottoms that aren't too much like a thong -- but, still show off enough backside to tantalize anyone else soaking up the sun.

If you wanna roll with the A-list, you better look like you're on the roster -- and this hunk’s not just walking the walk, he’s swinging the punches too.

The streets of NYC were filled with light blue shirts and plenty of heart over the weekend as hundreds of runners and walkers came together for the 9/11 Memorial & Museum 5K Run/Walk.

Gypsy Rose Blanchard is thriving and showing off that post-baby snapback like a boss!

GRB popped all the way off on IG Sunday -- serving a snatched 25-lb.-down bod in a white halterneck and flaunting her chic short 'do to seal the deal. She even hit us with a before pic to let the glow-up speak for itself.
