Great bodies like these don't just HAPPEN!

Justin Bieber and Hailey Baldwin work their BUTTS off working out! The pair didn't even take Memorial Day holiday off -- they hiked it to the gym for a sweaty workout and it's definitely paying off ... check out Hailey's long, slim stems in yoga pants as she headed to the gym and check Justin's shirtless selfie from the studio yesterday. #ThirstTrap!

Britney Spears seems to have been making a statement -- lunching ALONE in a cute off-the-shoulder top with skinny jeans and platform heels, her bikini top peeking out from underneath. Where was boyfriend Sam Asghari?

Spears was escorted by her bodyguards, one of whom was holding an umbrella at one point to shield Brit from our lenses, and it looks like she'd been enjoying the holiday by the pool -- with her sun-kissed skin pink and pretty. But why'd she go out to lunch by herself on Memorial Day???

What's a guy to do when he can't find a parking spot on Rodeo Drive?! Well, Travis Scott just parks his custom Range Rover wherever he wants and runs into Cartier to buy his girl some drip!

Scott got in trouble with Beverly Hills police for parking in a red zone when he made a mad dash inside the luxury jeweler to buy something for "wifey" Kylie Jenner. Looks like he avoided a ticket, though!

Justin Bieber doesn't go unnoticed when he's shopping for bling in Beverly Hills!

Biebs drew quite a crowd when he made a trip to Cartier and to Rolex yesterday on Rodeo Drive. Poor dude could hardly walk down the sidewalk without being mobbed -- fans taking selfies with him without even asking, people Snapping the whole thing, girls gawking, dudes trying to get his attention ... leave the poor guy alone!

Two things to note about this: 1) Justin can hardly keep his pants up and 2) Hailey's a lucky girl getting all this drip from her hubby!

Mrs. Bieber, in an all-black sweatsuit and Vans, headed back to the couple's Lamborghini Urus SUV before the shopping trip was over because she was feeling a little overwhelmed by all the attention. But Bieber had one more thing to do at the Rolex store and he didn't leave empty-handed! While Hailey had her Cartier bag, Justin had his Rolex sack. Looks like everybody got a treat yesterday!

After the shopping trip, JB headed to the recording studio with Hails, as he does every day. We feel new music coming soon and we can't wait!!!

Sweet! Kanye West surprised hubby Kim Kardashian with their first vacation since the birth of their baby boy Psalm on May 9.

Kim Instagrammed some pix and video of what was one of Celine's last performance dates at her eponymous residency, captioning one, "He surprised me with a date in Vegas with @celinedion." And, "5 years ago today I married my best friend ... KIMYE 4 EVA."

Meanwhile, Kim has been working on a side project ... her friend Paris Hilton's music video for the single, "My Friend's Ass." Gee, wonder what her inspiration was for that! We LOVE this f-ing song!!!!

Justin was in such a good mood on Friday -- we love when he's like this! Our respectful photographer kept his distance and didn't bug Bieber and wife Hailey Baldwin as they stopped for frozen yogurt at Pinkberry.

Hailey was wearing the "Bieber" cap she got when the two were engaged in the Bahamas last year. She sported a sports bra/crop top with sweatpants and Vans high tops. Justin was in tight jeans with an oversized tee and denim jacket, accessorized with Yeezys and a beanie.

As Jailey returned to his Lamborghini, Justin made the last-minute decision to give some cash to a man who appeared to be homeless. He left his gull-wing door open and sprinted over to the man on the Melrose Ave. sidewalk, handed him what appeared to be a $100 dollar bill, and ran back to the car.

Check out the video -- when we asked the man what Justin gave him, he says, "A $500 bill!" Wow!

Justin Bieber and Hailey Baldwin aren't just focused on Justin's mental well-being, they're focused on their physical fitness, too -- and hey, the two go hand-in-hand. So the husband and wife teamed up for a workout, on Friday, going to a private gym in West Hollywood to get their sweat on!

Seems Hailey is getting LOTS of swag from Adidas -- Hailey wore the 3-strip yoga pants with matching crop top and brand new white kicks while Justin wore a muscle shirt revealing his TONS of tatts.

These two look absolutely amazing and you may think, because they have celebrity genes, that they don't have to work to look as good as they do, but I bet they'd argue otherwise! Trips to the salon, the stylist and the gym keep these two in tip-top shape!

One might think Britney Spears, recently released from a mental health treatment facility, might be letting boyfriend Sam Asghari, or maybe her parents, "take the wheel," as it were ... but no, Brit's in the driver's seat!

Sam rode shotgun yesterday as the pair made their way back to Brit's Thousand Oaks estate. Queen B was laughing and talking to Sam as he appeared to be watching a video on his phone. Wonder what these two talk about???
