Hot Bodies

It's only April ... but bikini season is officially underway ... so sayeth Johnny Manziel's smokin' hot fiancee, Bre Tiesi.

Bre did a little bikini modeling at Posh Shop in L.A. -- showing off her insane physique.

Johnny and Bre got engaged back in March and no wedding date has been set -- but here's one lady who clearly doesn't need any of those bridal boot camps.

Instagram hottie Jen Selter took her famous ASSets on a beach vacation, and it looks like she took a new bf too ... Big Time Rush singer James Maslow.

Selter and Maslow were down in Tulum, Mexico over the weekend. She's renowned on social media for her butt ... but James is pretty easy on the eyes too.

No word if they're actually dating, but check out the pics -- they seem, at the least, very friendly.

Maslow actually performed at the Maxim Spring party, so it might have started as a work trip -- but based on these pics he's mixing in plenty of pleasure too.

We know this ... "WAGS" star Nicole Williams and her hot model girlfriends won't come home with many tan lines -- her bachelorette party is tops optional.

Nicole, who's marrying ex-NFL star Larry English, is over in Hawaii with her crew (including Natalie Halcro and Olivia Pierson) and when they took to the high seas Thursday ... some bikini tops dropped.

Models Shanina Shaik, Angelica Lee and Sharina Gutierrez and many more are on hand.

Justin Bieber knows the ole saying ... when in Brazil, find a smoking hot Brazilian model.

The Biebs is making the most out of his tour stop in Rio de Janeiro by spending a lot of time with Luciana Chamone. They were all up in each other's biz in the backseat of his ride Thursday.

Can't blame him. If he's smart ... there's a promoter working on extending the South American swing of this tour right now.

One in every port.

Halle Berry's happy to give you a glimpse of herself topless ... if ya got a bag o' chips.

Halle just posted this shot on her Instagram with the caption, "Me when someone says I'm coming over and I've got snacks."

Two things: Thank you, Halle. Also, 50 never looked so hot.

Oh, one more thing: Us, when Halle Berry says she wants snacks ...

It's good to be a professional athlete ... at least judging by the beach pics of their reality star wives and girlfriends!!

A bunch of the women from the "WAGS" show flew to Hawaii for Nicole Williams' bachelorette party -- as she gears up for her wedding to ex-NFL linebacker Larry English.

Nicole was joined by supermodel Shanina Shaik -- along with her "WAGS" co-stars Natalie Halcro and Olivia Pierson. Models Sharina Gutierrez, Tamie Tran and Angelica Lee were also on hand.

They tanned, they drank ... they took butt selfies.

Tarek El Moussa's flaunting his best fixer upper yet, and it ain't a house -- it's his ripped bod.

We're told the "Flip or Flop" star was super motivated to get fit after battling 2 cancers, recovering from debilitating back problems and, of course, his troubles with Christina.

Tarek wanted to show off his progress and posed for these seriously shredded pics. Dating site profile pic material?

Ireland Baldwin's butt quickly turned Malibu's beach into a scorcher.

The 21-year-old model showed off her bikini-ready curves during a photo shoot, and we gotta say ... dayummn!

Finally, some GOOD Dallas Cowboys news!

The entire Cowboys cheerleading team donned their hottest bikinis and hit up the Bahamas for their annual calendar shoot ... and it's just as awesome as you hoped it would be.

They went snorkeling, fishing, checked out sharks ... good times had by all.

Brandon Marshall could hardly believe it when we told him Jay Cutler posed for a nude pic on the beach in Mexico ... but when we SHOWED him, the NFL star lost his mind!

It's hilarious ... especially since Brandon has known Jay since they were drafted to the Broncos together back in 2006 and clearly didn't expect the QB to do anything like this!

Marshall even calls his wife over to look at the pic while laughing uncontrollably and ends with a funny message to Cutler.

Kelly Rowland's hanging out in Australia, and so is much of her ass.

Kelly put on her own kinda show on a beach in Sydney. Her one-piece was riding up a bit, but she's making it work. She's Down Under to judge the new season of 'The Voice.'

Jon Gosselin will make his debut as a stripper at a club in Caesars Atlantic City.

Management at Dusk Nightclub tells us ... the former reality TV star got involved through friends who are running the show -- called "Untamed Male Revue."

We're told it's burlesque-style, a la "Magic Mike" and "Thunder From Down Under." It's not a "hump your face" kind of thing.

Jon will be stripping down to his undies ... sorry ladies.

Jon's been rehearsing for a few weeks, even working out.

By the way ... the show debuts on April 1, Jon's birthday. No, not a cruel joke.

Ashley Graham looked off the hook, especially from behind, during a photo shoot in Hollywood.

Ashley was shooting photos Thursday for her new swimsuit line.

She nailed it ... hook, line and sinker.

Arianny Celeste is vacationing in Mexico ... and it looks like tops are optional at her beach of choice.

The UFC Octagon Girl and model let her girls free while enjoying the sunshine in Tulum ... and one of her friends even joined her.

And yes ... the buns were also out.

Ashley Graham made breakfast more fun for everyone when she used 2 bagels to cover up in a topless video, and it turns out ... that was precisely her mission.

We got the supermodel at LAX and asked her about the bagel bra ... she said she was just enjoying her morning, as we all should. As for what food she'll cleverly pose with next ...

Or maybe she'll just ditch it all and go full frontal.

Here's Usher lookin' smooth in Mexico ... without a single hair on his body!

The singer/Cleveland Cavs minority owner hit the beach with his wife, Grace Miguel, in an ultra-exclusive private estate resort in Costa Careyes ... on the south coast of Jalisco.
