Summer/Beach

Jennifer Flavin and her 20-year-old daughter, Sistine, are a lethal combination ... especially in bikinis.

Sly Stallone's wife and his middle daughter slipped into bikinis aboard a fancy yacht sailing off the South of France. This family affair wasn't just about soaking up the sun and enjoying the views. There was also important business, like ... selfies!

It would be pretty easy to mistake Mom for one of Sistine's 2 sisters ... who are also on the trip, btw.

While the international soccer world freaks out over rumors Cristiano Ronaldo will leave Real Madrid for Juventus ... CR7 couldn't be more relaxed -- chillin' on a beach in Greece.

TMZ Sports has photos of Ronaldo on Monday afternoon outside a 5-star resort in Messinia, Greece ... where he caught some rays with his girlfriend (maybe fiancee?), Georgina Rodriguez.

Witnesses tell us Ronaldo and his crew had their own private area -- complete with a massive, private security team.

We're told it appears Cristiano is with 15 to 20 people ... including several family members and his kids.

One source says CR7 is staying at a massive private villa on the beach -- and, when he's not tanning on the sand, he's being chauffeured around in golf carts (like a boss!).

According to reports, Ronaldo's move to Juventus could be announced any day now -- ending his 9-season run with Real Madrid.

The move is estimated to cost Juventus around $450 MILLION to sign Ronaldo through 2022 -- but, experts say it could be worth it because Ronaldo is the most bankable athlete in the world.

Selena Gomez seems to be taking the news her on-again-off-again ex, Justin Bieber, is engaged to Hailey Baldwin quite well. And why not? She's living her best life ... on a boat.

Selena surfaced Sunday in a friend's social media post, where she's seen in a bikini and in open waters near NYC. She's all smiles too ... no signs of distress after the Biebs got on bended knee for another woman, despite so much history with the dude herself.

She hasn't been spotted cozying up with anyone as of late, so it's possible Selena's enjoying some solo personal time post-Bieber ... and post-Weeknd, too. Good on her.

TMZ broke the story ... Justin proposed to Hailey Saturday night during their trip to the Bahamas. His security team made onlookers put away their phones before he popped the question ... and she said yes.

Remember ... Justin and Selena were together at Jeremy Bieber's wedding in Jamaica this past February, where the then-couple couldn't keep their hands off each other.

Guess the marriage bug bit JB harder than it did SG. To each their own, we suppose ... ¯\_(ツ)_/¯

Celebs, they're just like us ... in that they too hate the grossly hot weather in L.A. this week.

Lots of stars tried beating the crazy heat wave by either getting near a pool or beach, or just getting the hell out of town. Can't blame 'em -- temps were well into the 100s all over L.A. county, and stayed high through the night. Tough weekend for Angelenos.

Some of the A-listers who were spotted near agua this week included J Lo and A-Rod, David Beckham, Emily Ratajkowski, Kourtney Kardashian, Kendall Jenner, Rachel McCord and Eva Pepaj, as well as Hilary Duff and her brood.

Blake Griffin stripped down to his niftiest trunks for a beach day this weekend, but might've been one-upped by his own GF's swimwear ... yeah, bikinis are kinda her thing.

The Pistons power forward hit up a beach in Malibu Saturday with Francesca Aiello -- founder of Frankies Bikinis -- whom he's been seeing since at least last month. Unlike their last 'Bu outing, this time they got in the water ... and showed off their killer bods.

Yes, Blake was looking good in his pink shorts -- but, truth be told ... Francesca seems to have the edge over him here. That just us, though.

Leonardo DiCaprio got patriotic on the 4th of July by serving his country ... as well as serving his guests during a volleyball game that he was REALLY into.

The Oscar winner co-hosted an Independence Day shindig Wednesday in Malibu with his pal, Sean Penn, and got down for a save during a friendly match. Sean appears to have stayed out of the sand, but it's all good -- Leo had it under control. Kind of ...

He gets off to a rough start by knocking the ball into the net, but eventually finds his groove and makes a wicked dive to keep the rally alive. It ends up going out, unfortunately, but dude definitely gets an A for effort.

As if you haven't seen Josh Brolin enough on the big screen this summer, here he is again for the 4th of July ... getting his cornhole on with pro surfing legend Laird Hamilton.

The actor -- who's been in 3 blockbusters so far this year -- was out at a beach in Malibu Wednesday celebrating Independence Day with a good old-fashioned game of throw-this-sack-in-that-hole. Based on how damn happy he looks, we're guessing he scored well.

Laird was spotted on the beach alongside Thanos/Cable/Matt Graver too ... but he eventually made his way into the water and did what he, quite literally, does best -- surfed his heart out. This time, on an electric surfboard!

Joseph Baena celebrated the Fourth of July with a little red, white and blue ... and a tall drink of a blonde bombshell.

Arnold Schwarzenegger's son hit the beach Wednesday in L.A. with some friends and his smokeshow of a GF ... model Savannah Wix. They took a dip in the ocean, laid on the sand and soaked up some rays. Joseph and Savannah have been dating for at least a year. They seem to be pretty crazy about each other ... the proof's on his Instagram. He shows her off in a bunch of his posts, and ya can't blame the kid.

And while Joseph was in the ocean, Arnold was shaming us all ... hitting up a nearby Gold's Gym with Hugh Jackman. Arnold continues to be the picture of health. Just 3 months ago, he underwent emergency open-heart surgery for a catheter valve replacement.

Gigi Hadid and Emily Ratajkowski certainly pack a punch while on vacation -- ya know, the old one, two ... as in one and two-piece bathing suits. Whew!

The two models were spotted among a bunch of other babes soaking up some sun on a yacht Sunday near Mykonos Island, Greece. Emily appeared a bit less shy at the front of the boat with her poses. Booty and middle finger out, her 2-piece on full display ... well done.

Gigi, meanwhile, was changing in the back -- slightly shaded, but still smokin'.

RED ALERT!! Karrueche Tran's got major wheels in the sand ... and the alert is necessary because she showed off her speed while rocking a very small bikini that was hanging on for its life.

Karrueche's in Cancun with a friend, and the ladies decided to go head-to-head in a race on the beach. Again, ZERO tracksuits were worn during this athletic competition ... which is exactly why you should start clicking through the gallery.

Olivia Culpo and Danny Amendola are vacationing in Spain together ... and when we say the views are spectacular, we ain't talkin' the Torre de Savinar.

The on-again, off-again couple are getting some quality time on the Spanish islands this week ... but Olivia ditched the dudes for an all-girl yacht trip with friends.

So, what are they up to? Taking lots of photos of each other in sexy poses ... and for good reason, they're all insanely hot models.

As for Amendola, the two were spotted at dinner together the other night -- not the greatest body language -- but couply enough.

At least his tan looks great!

Remember, the two broke up back in March after dating for 2 years -- but they started hanging out again at a friend's wedding earlier this month ... and now, boom -- European vacation.

Totally back together, right?

Model Joy Corrigan is the kind of show-off we can get on board with ... especially when it involves several wardrobe changes.

Joy showed off her #SummerGoals body during a Poema bikini photo shoot down in Miami. She made a splash wearing a pastel-ish bikini, and not just literally. Joy -- who has also appeared on the cover of MAXIM in France -- changed into a burgundy outfit and that was also a hit.

Kourtney Kardashian and boyfriend Younes Bendjima have taken their love fest overseas ... literally.

The two were spotted on a private boat in Capri, Italy Friday soaking up some sun and enjoying the scenery too. The pair even got in the water for a quick dip.

Kardashian and Younes have been dating for well over a year. Younes -- who is just 24 years old -- was Kourtney's first serious relationship since officially cutting ties with baby daddy Scott Disick.

As for Scott, he's been steady -- for the most part -- with Sofia Richie who, like Younes, is very much his junior at just 19 years old.

Kara Del Toro, Josie Canseco and Delilah Hamlin are officially ready for summer ... and that collective sound ya just heard was the rest of America screaming, HELLLLLLL YEAH!!

Kara, Josie and Delilah -- along with a bunch of other hotties -- threw on some bikinis and walked the runway for Frankies Bikinis fashion show in L.A. Kara -- forever our favorite Carl's Jr. girl -- wore the hell outta her outfits ... hell, even those safety ogles. Sorry, goggles.

North West was just like any other kid enjoying a day at the beach, except she was there under the watchful eye of two nannies and a bodyguard.

Nori, who just turned 5, looked like she was having a swell time Wednesday in Malibu after spending her birthday earlier this week in the Big Apple with mom and dad.

Kim and Kanye weren't at the beach ... they're in Paris currently supporting Kanye's BFF, Virgil Abloh, at his first Louis Vuitton runway show.

Alec Baldwin might be popping out babies with his new wife, Hilaria, but his first born, Ireland, is one hot babe.

Ireland Baldwin, who's 22, hit the beach and lifeguard stand Thursday in Malibu for a modeling shoot. She had several swimsuit changes.

Ireland's mom is Kim Basinger and it looks like she got more of her mom's looks than her dad's ... because in some of the shots she's a dead ringer for Kim.
