Summer/Beach

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

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.

Model Mattie Maderos ain't afraid to get her hands -- and ass -- dirty with a little bit of sand.

The sometimes exes got in some snorkeling Thursday on the Big Island, and didn't seem the slightest bit concerned about the hurricane headed their way.

Brock O'Hurn isn't one to keep his dreamy locks wrapped in a man bun when he's gettin' ripped ... obviously he loses the hair tie.

We caught Brock out at the rings in Santa Monica where he got in an impromptu gym sesh -- sans his shirt. Now we know how he sculpts that bod of his for Tyler Perry's new TLC series, "Too Close to Home."

Mr. Man Bun hit some dips, pull-ups and even swung around on the rings a bit, flexing every muscle north of his belt.

Check out the vid ... #FullMoonFever.

We can't see any seashells ... but Farrah Abraham still had plenty to offer during a day at the beach.

The ex "Teen Mom" star packed her goods into a bikini, and put on a show for photogs in Malibu. After 3 boob jobs, you can see in these pics -- the struggle is real for Farrah's tops.
