Jeff Bezos and Lauren Sanchez are in a state of bliss post-wedding, floating like a water taxi through Venice ... and locking lips on a ship as hundreds of photogs snapped pics.

JB and LS were spotted in the city Saturday ... and, they gave paparazzi a show -- full of smiling, waving and, eventually, a big old kiss.

The two are dressed to the nines in the pics ... clearly headed to the next big event of their wedding week.

Jeff Bezos and Lauren Sanchez are kissing like there’s no tomorrow -- playing lovestruck teens while cruising to their fairy tale wedding rehearsal in Venice … while all the world watches.

The PDA was full throttle -- the couple were smooching and waving like royalty from their water taxi Thursday, with Jeff grinning ear to ear and Lauren beaming just as hard ... looking surprisingly comfortable for someone dripping in extreme, skintight couture

Lauren was serving bombshell -- rocking a sculpted off-the-shoulder midi with a metallic bodysuit that snatched her waist to perfection. If there was a pre-wedding health kick, it definitely did the job!

The woman in the viral video with Ja'Marr Chase says their awkward hug is being blown way outta proportion ... claiming she and the NFL star are just "old friends."

The lady at the center of the interaction addressed the noise on Monday ... shortly after TMZ Sports published a video of her and the Cincinnati Bengals receiver's cringeworthy moment in front of photographers in New York City.

In case you didn't see it, Chase -- who signed a $161 million deal in March -- was walking out of Zero Bond when the woman tried to hug him, but he gave her the cold shoulder.

Lana Del Rey’s still deep in that honeymoon haze -- 'cause she hit pause mid-performance not for a water break, but to maul her man with one heck of a kiss.

Yup, it all went down Monday night at Cardiff’s Principality Stadium -- Lana was mid-serenade with "Stars Fell on Alabama" when she suddenly veered off stage ... to lay a full-blown PDA ambush on hubby Jeremy Dufrene.

This wasn’t some cute little peck -- it was a full-on makeout sesh that felt way too private for the side of a stage. Like ... get these two a room, stat!

Jennifer Garner can't keep her hands off her boyfriend -- or her lips -- 'cause she was caught sucking face with him at a Los Angeles charity event.

The actress and her lover, businessman John Miller, popped up Sunday at a fundraiser for Save The Children, which helps feed starving children.

After completing a one-mile run, Jen was photographed sharing a smile with John while putting her arm around him -- and planting a big kiss on his lips!

As for the hungry kids ... Jennifer talked all about how she was trying to save them in an Instagram post five days ago.

Jen said she's been running one mile a day for 67 days to raise a dollar each day because "just $67 can help bring a child back from the brink of starvation." She said Sunday marked her final one-mile run -- and she certainly made the most of it with John, who was there to lend support.

The two are going strong despite recent rumors that Jen and her ex, Ben Affleck, had rekindled their previous romance. You may recall ... Jen and Ben looked cozy together at a paintball outing following Ben's split from ex-wife Jennifer Lopez.

Chrishell Stause and G Flip took part in the Dodgers Pride Night festivities ... and now we know they took full advantage of the atmosphere with a little make-out session on the field.

The couple posted a series of snaps Thursday from the game that took place last Friday ... including a few with them packing on the PDA for all in attendance to see.

Along with their lovin' snaps ... CS posted pics of her with friends and fans -- making sure to give GLAAD a shoutout. Among the slew of shots ... CS included the Dodgers org message that federal agents were denied access to the stadium parking lots on Thursday -- clearly spurring her Pride post.

Josh O’Connor’s been grinding since "The Crown" -- but now he’s pressing pause for some seaside smooches with his GF, Alison Oliver.

The sun was scorching -- and so was their chemistry. Josh couldn’t take his eyes off Alison, who stunned in a chic bikini, totally carefree and soaking up the love.

Marcus Jordan was back in Miami Beach on Sunday ... and while he hit the sand with a different woman than Saturday -- the results were largely the same.

Michael's son and his new gal pal were all over each other -- this despite Marcus having a similar afternoon with an entirely different woman some 24 hours prior.

34-year-old MJ and the Larsa Pippen lookalike -- who was wearing a tiny, baby blue bikini -- hugged on one another ... and passionately made out in the ocean as they enjoyed several hours in the South Florida sun.

Marcus Jordan ain't missin' his ex Larsa Pippen one bit ... 'cause he's hangin' with his Larsa lookalike and they're turning up the heat in the hot Florida sun.

Michael Jordan's son and a mystery woman are now definitely an item after they were first seen out together last year following Marcus' break up with Larsa.

Check out photos and video, obtained by TMZ, which show Marcus and the woman in major PDA mode while kicking back at the beach in Miami Saturday.

Eva Longoria was living la vida luxe -- flaunting her killer beach bod while soaking up the Spanish sun with hubby José Bastón in tow.

The actress turned heads in a dangerously low-cut peach swimsuit that hugged every curve -- and judging by the PDA, José couldn’t take his eyes -- or hands -- off her.

One thing about Eva -- she wasn’t just sunbathing pretty. She was all in ...ocean frolicking, PDA-flashing, full of laughs and living her best beach life.

Jennifer Garner's got one guy on the brain -- longtime BF John Miller -- and the two were caught locking lips like horny teens outside his L.A. pad.

There was no glam, no red carpet -- just Jen and John in their everyday getup, sharing a sweet, low-key moment that showed them completely wrapped up in each others' arms, and in their own world.

Singer-Songwriter FINNEAS scooped up his GF Claudia Sulewski and brought their PDA overseas -- the cutesy duo recently hit Berlin and Amsterdam to join Billie Eilish on her "Hit Me Hard and Soft" tour.

Boating on the waterways of Berlin, 27-year-old FINNEAS and 29-year-old Claudia snuggled up to each other and posed for a photo-op sesh.

Claudia shared this lit pic of FINNEAS joining his younger sister onstage for an epic performance -- the sibling duo jammed out with their electric guitars and brought the fire to the entire arena!

JoJo Siwa’s not just soft-launching anymore -- she’s full-throttle flaunting her romance with Chris Hughes, declaring she's head over heels and rubbing her cheeks 'cause she’s smiling so hard.

The former "Dance Moms" star, who started a platonic connection on "Celebrity Big Brother UK," has now developed a beautiful connection -- and even her family's clocked how much happier she's been compared to recent years.

JoJo clapped back at rumors of a PR stunt to The Guardian, basically telling the haters they’ve clearly never been around her and Chris together. And while she’s not speaking for him, she says her happiness is so real, it’s radiating off her.

JoJo Siwa and Chris Hughes are taking their coupling from the streets to the sheets ... snuggling up to one another in a new pic -- and, it's hard to tell if they're wearing clothes!

Hughes shared a photo of himself and JoJo lying back underneath the covers. Her arms are wrapped around his chest, and she's resting her head on his broad shoulders.

In return, Chris is smooching JoJo's forehead as he takes the selfie -- writing, "Sleeepinnn beauty" underneath the pic as a caption.

Timothée Chalamet brought along his good luck charm Kylie Jenner for the Knicks-Pacers playoff game Thursday night, but they didn't seem to catch much of the on-court action because they were too busy making out.

The famous couple -- and diehard Knicks fans -- had some of the best seats in Madison Square Garden for Game 5 of the Eastern Conference Finals -- although it didn't really matter since they were mainly focused on their own personal activities.

Check out the shots of  Kylie sucking face with Timothée, which practically went on all night. Every time a camera zeroed in on the lovebirds, it appeared they were locking lips. A video was also posted to Instagram by Page Six that showed Kylie and Timothée smooching with their hands all over one another.

As for their fondness for the Knicks, Timothée wore a blue and orange jacket to match his favorite team's colors. Kylie was sporting a Knicks cap at one point in the night with a tight white shirt and black leather pants.

Despite all their PDA, the pair didn't miss the entire Knicks' 111-94 victory over the Pacers. Photos showed them periodically watching and rooting for their team.

This isn't the first time Timothee brought his good luck charm to a Knicks game. You may recall, Kylie and her sister, Kendall, joined Timothée at the Knicks-Celtics semifinal game earlier this month -- and the Knicks ended up with the big win.
