Hot Bodies

Model slash entrepreneur Dolly Castro's best muscle is in her smile -- KIDDING!! Although it's open for debate.

Louisiana-bred model Lindsey Pelas doesn't need a lifeguard watching over her as she wades in the Pacific.

Spencer and Heidi Pratt are closer than ever ... based on the hip to hip action they're getting down in the Caribbean.

The ex 'Hills' couple looks to be having a blast jet skiing and hanging on the beach in the Bahamas. No one thought they'd last, but check 'em out almost 10 years later still together ... still as thirsty as ever.

Justin Timberlake proves yet again he can look dapper in just about anything -- vintage lifeguard swimsuit? Check.

Justin rocked the wardrobe on a lifeguard stand in NYC while shooting a Woody Allen film.

Lady Gaga looked like she was hittin' a club instead of Tony Bennett's 90th birthday tribute -- still, we're willing to bet there were no complaints.

Gaga showed up to Tony's birthday celebration Thursday night at Radio City Music Hall with a see-through black dress ... hiked right up to her crotch.

She looked awesome, but that's a dangerous outfit to wear around the elderly.

Taking a hint from her name, sunshine and hotness go hand in hand ... or, in this case, cheek to cheek for model Sommer Ray.

We got Sommer and her pooch at the beach this week soaking up -- and washing off -- the L.A. heat.

Mom, boob, a butt tuba -- all things you might relate to Kim Kardashian, and much like her ... they all look the same from front to back.

Ok, enough fun with grammar ... what's important here is Kim's front and back were on display in lingerie Thursday in Miami -- and yes, the paps got great shots as she came and went.

There's really no wrong way to look at these pics.

Model Victoria Brown got her stretch on ... then stripped down to a bikini and did some splashing around.

The Wilhelmina model and fitness guru looked very flexible in Playa Del Rey. Her workout musta made her a little sweaty though ... because she hopped in the ocean to rinse off afterward.

Joe Jonas looks like he's shaping up to be a fine fighter ... emphasis on fine.

We got Jonas Bro #2 out in Bev Hills where he was practicing his hook and uppercut against women's boxing champ Ava Knight, showing off his sculpted bod in the process.

He's been training hard lately, and so has Nick. So we gotta ask ...

Actress Lyssa Roberts -- the Wimbledon streaker from "7 Days in Hell" -- has at least part of a backside grab mastered.

Not hard to figure out which part, once you take a look at her coasting along the Playa del Rey beach boardwalk.

Instagram model Analicia Chaves got a little sand on her backside while enjoying a day at the beach. Luckily for her ... it was easy to rinse off.

Liziane Gutierrez doesn't need Chris Brown or Jason Derulo to party it up -- she can get wet and wild all by herself.

We got the Brazilian model in Marina Del Rey, where she jumped right into the water in her thong ... and a see-through top.

'Bachelor' alum Samantha Steffen is used to the sand after a stint on "Bachelor in Paradise."

Arika Sato snaps swimsuit selfies by the seashore ... try saying that 10x fast.

Lady Gaga's full of crop tops in London, which means she's letting almost everything hang out.

Gaga left Capital London early Friday morning with a giant denim wedgie -- and cup of coffee.

She's got a new song out, and if this is how she's gonna promote, we say ... keep plugging away, Gaga!

Stephani Costanza is usually speeding around tracks in fast cars -- but lucky for us ... she took her sweet time soaking at the beach.

We got the former Miss Toyota Grand Prix model out in Venice, where she laid out to sunbathe and eventually got wet in the waves.
