Summer/Beach

Chris Hemsworth's mini-me caught a clean wave Down Under worthy of a standing O.

Thor and his wife, Elsa Pataky, took their 3-year-old twin sons, Sasha and Tristan, to Byron Bay in Australia for surfing lessons. Sasha wasted no time proving he's destined for greatness in the water ... looking every bit like a pro with a low-center of gravity and perfect stance.

Katharine McPhee's idle time looks just as good as her 'Idol' time -- in fact it looks hotter, due to her butt-hugging swimwear in Hawaii.

Kat's on vacation and Thursday she was ready to swing into the weekend ... courtesy of some chill time in a hammock. Her bf, David Foster, wasn't around, but she seemed to be in a deep FaceTime convo with someone. Based on the Blue Steel looks she was flashing ... it could've been David.

Looks like Katherine knows how to work her angles. All of them.

The real Victoria's Secret was exposed in Miami, which is that lingerie works just as well as a bikini on the beach ... maybe better.

VS models Lais Ribeiro and Cindy Bruna were doing a beach photo shoot Wednesday, and passed on the traditional swimwear ... going simply bras and panties instead.

We're sure they didn't get a single complaint from the locals. Besides, a two piece is a two piece, right?

Josephine Skriver found herself at the beach without a standard sexy-as-hell swimsuit, so instead ... she went with the pretty-in-pink lingerie look.

The Victoria's Secret Angel rocked the racy lingerie during a photo shoot near the beach in Miami Wednesday ... and she certainly stood out on some sort of stone slab.

Dakota Johnson and Chris Martin are going public -- the new couple strolled on the beach over the weekend, packed on some PDA and, for good measure ... hung out with Kenny G.

Chris and Dakota have been dating for a few months, but previously took great measures to keep it private. That all changed Sunday in Malibu ... where the "Fifty Shades of Grey" star and Chris looked inseparable.

They had some unexpected company on the beach when Kenny G popped up, sadly without his saxophone. So, no Coldplay-Kenny G collab.

That Dakota's a lucky woman.

Models Candice Swanepoel and Doutzen Kroes are on vacation in Bahia, Brazil together and still bringing their VS A-game to the beach even with a bun in the oven.

The on-hiatus VS and former VS model are no strangers to posing in the sand in tiny bikinis and over the weekend, they both did it with a ton of arm candy.

Swaenpoel brought her son along for the ride, while Douzten was there with DJ/husband Sunnery James. Sure, that may sound like a buzzkill ... until you see them in their bikinis.

Britney Spears is taking a load off in Hawaii after ending her residency in Las Vegas -- and we are so thankful for the break ... and the view.

Brit was spotted rockin' a yellow bikini on a Hawaiian beach Wednesday -- just a few days after she performed her last residency show in Vegas for New Year's Eve.

She went out with a bang then, and it looks like she's still banging now. Britney's toned figure was on full display ... and, Lordy, does she look good.

The holidays are over for us normies, but not for UFC star Anthony Pettis and his smokin' hot fiancee ... who are out in sunny Aruba getting their safari on!

It ain’t just any average trip -- Anthony popped the question on NYE at the Aruba Ritz-Carlton ... and Lisette said yes!!

Since then, the future Mr. and Mrs. “Showtime” have been living it up on the island -- exploring ancient ruins, off-roading at a safari and hitting the beach with flamingos are just a few of the activities they've been getting into.

Not like Anthony really cares -- anything with Lisette is winning.

Congrats!!

Mark Wahlberg's swole body should be motivation to hit the gym -- at least until you quit your New Year's resolution in 3 weeks -- but his diving form might need some work.

Mark's been vacationing in Barbados with his wife and 4 kids and having a blast ... as you can see in these pics of the action star attempting a dive off a doc into the Caribbean.

Take off was strong, but midway Mark looks like he's heading for an awesomely painful belly flop.

Diddy's girlfriend needed a little sun before a little bubbly for New Year's -- and she definitely got it ... on all sides.

Paps got Cassie hitting the beach in Miami hours before her guy threw a blowout of a NYE party at their house -- where Diddy ended up helping a drunk woman who'd passed out.

It might not snow in L.A. but bet your ass Nicole Williams still knows how to turn a beach into a winter wonderland.

The 'WAGS' star was struttin' her stuff on a beach in Santa Monica where she wore the hell out of a mesh one-piece from her Nia Lynn swim collection. This attire's quite the switch-up from what we're used to seeing her in -- usually very little to nothing at all ... not that we're complaining.

Arianny Celeste and her equally hot homegirls are knocking out the beaches in the Bahamas right now ... and tops are optional.

Unclear where the UFC Octagon Girl's hangin' loose in the video ... but Arianny and friends are clearly feelin' themselves, jammin' out to Manu Chao's old-school track about loving life (and weed).

If you like what you hear, Celeste -- an aspiring recording artist -- says you can cop her new single that drops on Friday.

Or ... you can just drink in her other talents. Your call.

Matthew McConaughey's just a beach bum these days ... who happened to find his way on stage with Jimmy Buffett to dance along to one of his legendary island jams.

The Oscar-winning actor's in Miami shooting for his upcoming film, "The Beach Bum" ... and showed off his groovy moves while Buffett played his hit song, "Volcano," during one of the scenes.

McConaughey plays a rebellious stoner named Moondog in the Harmony Korine film, and judging by the vid ... Moondog's in paradise when Buffett's rocking out.

"The Beach Bum" comes out in 2018.

David Beckham's beach bod is unlike any dad bod you've ever seen ... you're welcome.

The 42-year-old -- cool dad status in full effect -- hit up Malibu Sunday with a bunch of his kids to cool off after a blistering weekend in Los Angeles. A little boogie boarding did the trick to cool the brood in the ocean.

Perhaps the only disturbing thing we see in this family outing -- using a beach volleyball as a futbol.

There's no doubt Jason Momoa was born to play 'Aquaman' ... he was like a rock in the surf, making sure his fish wife played by Amber Heard didn't get swept away in between takes.

Jason and Amber filmed scenes for the upcoming blockbuster on the Gold Coast in Australia.

They've been down in Oz for months but this is the first look of them together in Aquaman's natural habitat. Jason held his ground even with out Aquaman's trident.

Aquaman vs Ocean ... 1-0.

Seasons change, but Johnny Manziel's future wife, Bre Tiesi, doesn't change (out of her bikini) ... 'cause she's still killin' the 'gram with super hot, nearly-naked photos, even though it's nearly Fall.

We were just casually browsing Bre's social media when we noticed she's gone on a bikini barrage the last couple weeks, and we thought the fair thing to do was to bring it to you guys.
