Summer

Single mom life seems to be treating Irina Shayk well so far -- VERY well based on how incredible she looks on a family vacay in Spain ... with Bradley Cooper nowhere in sight.

The supermodel's enjoying some yacht and beach time in Ibiza with her daughter, Lea De Seine, Tuesday and it looks like Irina's mom, Olga, was part of the girl squad too.

Irina stood out like she normally does, but even more so thanks to a sexy lime green swimsuit accentuating her figure ... as she hopped off the boat and took a dip in the sea. Wonder if she was inspired by Rita Ora?

We're told Irina and her family had yachts of fun for a few hours before heading back to land and calling it a day.

As we've reported ... Shayk and Cooper agreed last month to share custody of their daughter and live in the same city. Looks like Bradley's might have to step up his vacay game when it's his time with Lea.

The ex-couple started dating in 2015 and had their baby girl in March 2017.

This summer is looking ab-solutely scorching hot!!!

These sexy stars are making their way outdoors to to burn up the Hollywood scene by doing cool things like hiking, beaching and taking a dip in the pool ... the tops are coming off and the shirtless selfies are taking over social media.

See all the flexin' fellas ripping things up this season by flipping through our gallery of hot summer stomachs -- Get a really good look at the celebs showing off their six packs and pecks -- then see if you can guess which jacked star is responsible for the real heat.

Model Cat Kennedy's new bathing suit definitely hits the spot ... to purrrfection.

Cat was spotted -- haha, spotted -- showing off her beach bod in a leopard print bathing suit for a little fun in the sun next to the world famous Santa Monica Pier. Lots of moods to appreciate for sure ... from pensive and playful to mysterious and chill.

Jennifer Lopez -- who regularly steps out in only the bare essentials -- covered her entire bod in the sweltering NYC heat, but it may be a brilliant marketing ploy.

It was 90 degrees Friday in the Big Apple, but felt north of 100 because of humidity. That's why walking out in Guess threads from head to toe would certainly draw attention.

You may recall ... less than 2 months ago Guess announced a J Lo "It's My Party" line. Camo is not part of her line, but it could be.

Henry Cejudo wins again!!!

The UFC superstar is down in Mexico on vacation with a smokin' hot lady on his arm ... and by the looks of things, he's having a GREAT time!!!

Triple C (two UFC championship belts and an Olympic gold medal) was spotted out in Tulum with a new lady friend.

We're told the mystery lady is a soap opera actress from Brazil named Sandra -- and by the looks of it, we're guessing she also does some modeling (if not, she should).

Our Cejudo sources tell us the two are vacation together (it's not like he met her down there) but they're not an official boyfriend, girlfriend thing just yet.

As one source put, "He's still single man. He's having fun."

Cejudo is having one hell of a year in 2019 -- he defended his UFC flyweight belt in January against a juiced up T.J. Dillashaw and then in June he starched Marlon Moraes for the bantamweight title.

Will Smith and his family are in full vacation mode on a breathtaking Italian island ... golfing, swimming, boating and hopping on jet skis for some summer fun overseas!!!

Will brought the gang with him to Sardinia ... and they added a new guest to the bunch, Willow's boyfriend Tyler Cole.

The only thing more beautiful than the Smith clan ... the sparkling blue waters. Willow and Tyler dove right in, while Will and Jada Pinkett Smith stayed on land and hit the links for a competitive round between husband and wife.

Joe Jonas and his bride, Sophie Turner, are still honeymooning under the Southern Italian sun -- and even though they're two weeks deep ... they're treating each day like it's their first.

The couple was spotted Sunday near the shores of the cliffside village of Positano -- and as they made their way down a set of stairs to board a boat ... Joe made sure to capture all the moments.

Sophie had his back too -- he was looking one way firing off shots of the coast, and she was keeping watch on the other side ... making sure he didn't miss anything. Teamwork makes the newlywed dream work!

Before their boat ride, Sophie and Joe enjoyed themselves a couple refreshing spritzers with some smooching in between. It's like they just left the altar!

The couple's been in Italy for at least 14 days now -- they got hitched in late June over in France ... and then jetted down to Italy to soak in some rays ... like just about every other famous traveler, it seems. The also-freshly-married Kat McPhee and David Foster were also honeymooning on a nearby yacht.

It's that time of year again ... Cristiano Ronaldo is launching his new CR7 underwear line -- and shocker, he's thrusting his own man junk front and center of the new campaign! 

The soccer superstar stripped down to his skivvies to showcase his new High Summer collection of his CR7 undies ... and yeah ... they make more than his eyes pop.

Ronaldo says the design was inspired by summer sunsets, saying, “Summer is my favourite (he spells it weird because he's European) season and I love the time of day when the sun goes down and the sky is vivid."

"I wanted to capture that feeling in my HS19 campaign, using intense colour (again with the weird Euro spelling) that’s bold, rich and compliments my new collection. I wanted the campaign to have a really relaxed feel. Summer is the time of year when I have some time to chill out, so I wanted to reflect that.”

Ronaldo takes his looks about as seriously as his game ... and the dude is on a quest to make the most stylish underwear out there.

"Essentially, I want to create underwear that looks so good that I want to wear it on the beach, rather than covering it up with my swimwear!”

In case you're wondering ... Ronaldo's underwear usually costs about $38 for a 3-pack. 

Kylie Jenner is killing two birds with one hot, steamy stone -- celebrating both the launch of her summer skincare line ... and, apparently, National Nude Day. Yay to multitasking!!!

Ms. Jenner and a bunch of her girlfriends flew out to Turks and Caicos Saturday night in a pimped-out private jet that was decked in white and pink 'Kylie Skin' signage -- with branded pillows, sleeping eye covers and even flight attendants. Oh, and did we mention the matching custom sweat suits? Yeah, everyone got one of those too.

The occasion ... Kylie's dropping few new products for a her skin line later this month -- a coconut body lotion and scrub, as well an SPF 30 body oil. They're available July 22.

She brought along a handful of her BFFs -- including Draya Michele, Anastasia Karanikolaou, Yris Palmer, Sofia Richie and others -- not to mention Travis Scott and baby Stormi.

When the ladies (and Trav) touched down, they got the five-star resort treatment, with hired handlers greeting them with carved-out 'Kylie Skin' coconut drinks, robes and anything else you might need on a luxury vacation. At one point, Kylie got an itch to get nakey.

Unclear if she knew Sunday was THE day to disrobe in America, but she definitely made the most of it by partaking ... snapping this sexy shot, posing in her birthday suit. 

Katharine McPhee and David Foster are putting themselves in serious contention for best honeymooners in this summer of newlywed celeb love ... just look at them!!!

KM and DF are soaking up the sun during their post-wedding getaway off the coast of the gorgeous Italian island of Capri. Yacht style, the only way to go! Kudos to the groom ... not for his swimwear, but for getting Katharine to say, "I do." Her beige bikini highlights what we already knew ... she's an absolute spettacolo di fumo (that's Italian for smoke show)!!! 

Kat started out in a sun dress, and then stripped down to her two-piece as she laid out on the boat ... eventually even going topless while tanning next to her hubby. 

BTW, Dave and his new bride appear absolutely gaga for each other under the Italian sun -- like we said, Chris Pratt and Kat Schwarzenegger might have some competition on the most affectionate couple in Hollywood. Joe Jonas and Sophie Turner too, for that matter ... who also happen to be honeymooning in the area.

Jason Momoa looks super chill as he lounges poolside in Italy ... proof even Aquaman needs some time away for a little R&R. 

As you can see from his bulging biceps ... Jason still has his superhero bod in full swing after playing the king of the sea on the big screen ... and he's taking some time off in Venice following a busy weekend in France. 

Jason and his wife, Lisa Bonet, have been on some family business in Europe, travelling overseas for the wedding of his stepdaughter, Zoe Kravitz.

Chris Pratt got burnt to a crisp on his honeymoon ... and he wants you to see it from top to bottom. 

The 'Avengers' actor posted a photo Saturday of his entire backside -- ass crack included -- which was sunburned to the max ... minus his pale white cheeks, of course. He and his new bride, Katherine Schwarzenegger, just got back from their Hawaiian honeymoon, BTW.

Chris captioned the pic, "Suns out guns out I might have got(ten) a toouuuch crispy on the honeymoon" ... adding "#Aloe." You can say that again ... this looks mighty painful. 

Luckily for him, one of his Hollywood pals already has a solution to his hot mess of a problem -- Gwyneth Paltrow commented on his post, writing ... "I've got some goop for that." Kat also responded to it, throwing up a bunch of flame emojis. 

Chris and Kat have been in Lanai -- a separate island right off the coast of Maui -- since at least Wednesday, celebrating their marriage two weeks after tying the knot. 

They held off embarking on their honeymoon for a bit ... opting for some gym sessions in L.A. instead. Looks like they've done the deed though, and now they're back in the homeland.

It's definitely not summertime until some float photos start flooding your feed!

Stars such as Jesse Tyler Ferguson, Bella Hadid, Lindsey Vonn, Kendall Jenner, and Shay Mitchell are getting into the spirit of the season by soaking up the sun on their buoyant birds.

These famous floaters are taking full advantage of the weather and making sure they have some fun while they are at it!

Get a glimpse at the faces lounging in style by diving right into our gallery of celebrities on flamingo floats ... See up close and personal who is flocking towards some sunshine!

G-strings ain't just for chicks ... just ask golf superstar Brooks Koepka! 

The #1 ranked PGA player in the world decided to thong out for a friend's birthday party in Florida on Friday -- and it's clear ... dude ain't shy about it!!!

The 29-year-old butt-flossed up and bared his bod while drinking beer on a PonTiki boat in South Florida ... and tested the thong durability when he jumped off into the water.

The theme of the party seemed to be some sort of redneck vibe -- at one point, Brooks was rockin' a shirt that read, "Save a Horse, Ride a Cousin."

BK's hot girlfriend, Jena Sims, got in on the costume fun -- sporting a bathing suit inspired by that neon green man-thong from "Borat."

Blake Griffin and Chandler Parsons are LIVING UP THE SINGLE LIFE ... partying with a whole bunch of insanely hot bikini-clad women on a yacht in Ibiza -- and the pics are AWESOME!!!

The two NBA stars were all smile on the booty boat ... and it's pretty clear why -- it looks like fun!

Besides being young, ripped and pro athletes ... Blake and Chandler are also super rich!!

Blake's reportedly made close to $200 MILLION in his NBA career -- and Chandler's around $127 MILLION.

As we previously reported, Parsons recently broke up with his longtime model girlfriend, Cassie Amato ... so he's looking to rebound -- and it seems he's doing pretty well!

Between the two of 'em, Chandler and Blake have dated some of the biggest stars in Hollywood ... from Kendall Jenner (Blake) to Bella Thorne (Chandler) to Toni Garrn (Chandler) to Arianny Celeste (Chandler) to bikini mogul Francesca Aiello (Blake).

Cindy Crawford's daughter, Kaia Gerber, truly got it from her mama -- which couldn't have been more clear than in these matching vacay views.

The supermodel is vacationing with her hubby, Rande Gerber, and their kid right now down in Miami, where mom and her little girl (who's 17, BTW) wore similar swimwear ... black bikini tops, revealing their great figures and spectacular family genes.

Like her ma, Kaia is also a well-established model in her own right. She's done campaigns for Chanel, Prada, Jimmy Choo, Alexander Wang and Marc Jacobs, among others. Definitely following in her parent's footsteps ... no question about that.

Just to drive the point home, check out the position they were both in at one point while relaxing by a pool. Interestingly, Cindy and Kaia both seemed to be a bit distracted as they laid out -- making it that much more obvious ... Kaia's a chip off the old block.

Considering how incredible Cindy still looks at age 53, ya know Kaia's gotta like her chances at a long and prolific career. Not too many mother-daughter combos that can do it like this.
