Summer/Beach

'Bachelorette' star Kaitlyn Bristowe and her fiance, Shawn Booth still aren't hitched, but they look like they're practicing for their honeymoon.

The couple are on a romantic getaway in Hawaii .... stand up paddleboarding, drinking and such.

They've been engaged since last July's season finale -- so, as of now, they're one of the rare couples from the show that could actually be the real deal. For now.

Rihanna is a multitasker even on vacation ... rinsing the sand from her crack and chugging a brewski all at once!

RiRi cooled off in the Caribbean before the European leg of her tour kicks off next week. BFF Melissa Forde managed to snap these photos for the scrapbook and, we gotta say, did a pretty good job.

Sports Illustrated cover girl Ashley Graham was back in a swimsuit, although this one had more coverage than her S.I. shoot ... in certain areas, anyway.

Ashley hit up famed Muscle Beach in Venice for a photo shoot where she showed off just what a versatile model she is, and looked beautiful doing it.

Charlotte McKinney's latest sizzling bikini shots will have you running for the border ... 'cause she's down in Mexico.

Kate Hudson made sure she got plenty of sun where it normally don't shine during her Hawaiian vacation.

Kate's on Oahu for a girls trip with mom Goldie Hawn.

LeAnn Rimes locked up "Wife of the Year" -- just an educated guess -- by sucking face with a smoking hot girlfriend in front of Eddie Cibrian.

The couple was hanging in Malibu on Monday for a family BBQ, but their family fun probably looked much different from yours. LeAnn and a redheaded bikini-clad chick went on a selfie-fest on the beach, complete with full mouth kisses. No clue who the friend is, but they're VERY close.

LeAnn and her husband hugged a little bit too ... if you're into that.

Hailey Baldwin got a head start on her tan lines by hitting the beach on Florida's panhandle ... in a couple of bikinis that scream #wcw.

Hailey's frolicking on Rosemary Beach, just up the coast from Panama City. She and her sister, Alaia, are kicking it down there in a vacation home ... a short drive from the beachfront.

Kelly Rohrbach is totally comfortable in that classic "Baywatch" one-piece, and just as comfortable out of it ... based on the nip slipping that went down during a photo shoot.

Kelly was posing Monday in Malibu for a Vogue spread that looked like a big promotion for the "Baywatch" movie -- and also for her amazing body.

Heidi Klum adhered to an age-old adage -- when in France, do as the French do.

Klum and BF Vito Schnabel had some fun in the sun Wednesday in the Gulf of Saint-Tropez. Vito was pretty grabby as they soaked up some rays and took a dip in the Mediterranean Sea.

He's out of the NFL, but ex-NY Jets safety Kerry Rhodes is still in game day shape -- and flexed his physique this week during some beach football with his actress fiancee.

BTW, Rhodes is engaged to actress Nicky Whelan -- the hot chick Owen Wilson almost banged in "Hall Pass."

One day Louis Tomlinson is changing diapers, the next he's sippin' Pacifico and taking off his girlfriend's bikini top in the Mexican sunshine.

Louis took a break from dad duties with 4-month-old Freddie for a vacay with girlfriend Danielle Campbell, who needed his help getting rid of her tan lines.

Vita Sidorkina's making one hell of a case for Victoria's Secret to keep its swimwear line.

The 22-year-old Russian model was one of several VS Angels flaunting their talents Tuesday in Miami Beach ... as the lingerie giant rolls out its swimwear line in time for summer.

Joanna Krupa's ridiculous body proves yet again she's the finest Polish export ever -- sorry, smoked sausage.

The model and ex-Real Housewife hit Miami Beach in a smoking hot sequined bikini. Her husband, Romain Zago, was there too 'cause apparently Joanna needed something to climb in the water.

If there's one thing Kristen Wiig learned from shooting "Ghostbusters" it's ... NEVER cross the streams -- unless, of course, a tall dark mystery guy offers his stream on a romantic beach in Hawaii.

Beats getting slimed. We imagine.

The mystery guy is Avi Rothman. People says she's been secretly dating the writer/producer for a few months.

It was sunny and 75 in Los Angeles Tuesday ... so UFC superstar Paige VanZant hit the beach.

Model pose? Check.

Bathing suit handstand? Check.

Butt selfie? Check and mate.

BTW, don't be jealous of the weather ... it's only supposed to be sunny and 69 today.

Ellie Goulding took her flawless bikini bod to Miami's South Beach the day after taking in Beyonce's Formation concert -- where she had a killer view.

Speaking of which ... no need to ask why you got Ellie on your mind. That's kinda obvious.
