The Summer Olympics in Rio are less than a week away, but the hottest contest down there is Miss Bumbum 2016 -- and all signs point to a stiff competition.

Kiss-tiano Ronaldo????

Seems someone has finally tamed the tan stallion ... because Cristiano Ronaldo was getting VERY up close and personal with a hot blonde in Miami this weekend ... and even planted a kiss on her!

The two were all about the PDA -- holding each other in the pool ... and literally getting on top of each other on the deck chairs.

At one point, a smokin' hot friend came over and began smackin' the lady on her butt -- and no one complained.

Despite all the attention, Ronaldo has yet to put her on his Instagram page -- so, it's not official ... at least not yet.

11:09 AM PT -- MYSTERY SOLVED!!!

The woman is Cassandre Davis -- a Florida-based fitness model who's racked up more than 500k instagram followers due to her ass-centric workout videos.

Jay Z and Beyonce are running the best damn summer camp EVER for Blue Ivy ... latest stop -- Monaco!!!

The Carters hit the Mediterranean with their daughter and some friends over the weekend. Check out the pics ... Bey looked flawless while Hova rocked a Gilligan bucket hat.

This trip came just a few days after Blue was sleeping in Mom and Dad's $19,000/night suite in Paris.

Kylie Jenner got her birthday party started early -- and she did it partially nude ... naturally.

The soon-to-be 19-year-old rolled deep Sunday night with her whole 'KUWTK' krew into The Nice Guy for a huge party ... 10 days before her actual born day.

Kim Kardashian showed up with a new short 'do ... and Tyga also showed up, but the birthday girl could not be upstaged.

KJ was the sheer winner.

Lindsay Lohan is just barely holding it together ... and the 'it' we're referring to is her rack.

LiLo had way too much confidence in a strappy black wrap Saturday as she ventured out on the island of Sardinia. She's still yachting around Italy with friends during her getaway from fiance Egor Tarabasov.

As we first told you ... Linds thinks they can work things out after their blowout fight in London, and you can see she's still flashing her engagement ring.

No doubt, it's gonna be a struggle ... for those tassels! Damn.

"Love and Hip Hop: Atlanta" star Althea Eaton is a free woman again after spending just over a week behind bars.

Althea cruised out of an ATL jail Friday ... already rocking her heels and looking like she's ready for the weekend.

Althea was reportedly jailed after a restraining order hearing -- her estranged fiance, Benzino, was getting one against her, and she allegedly made contact with him after court. Major no-no ... and the judge locked her up for it.

We're not really sure why Irina Shayk even bothered with this bikini.

The supermodel was on vacay with Bradley Cooper -- they moved on to the Italian isle of Sardinia.

Looks like Irina was solo on the beach as her butt was devouring a micro bikini. Bradley? For some reason he was playing tennis.

Julia Roberts said it best ... big mistake, Bradley. Huge.

Gigi Hadid's patriotic outfit is a smoking reminder that EVERY day should be the 4th of July.

Gigi modeled the hell out of a red and white striped swimsuit Thursday in L.A. for a Tommy Hilfiger photo shoot.

David Guetta's got major dirt on his GF, and she's got it on him too ... 'cause it's just what ya do in Ibiza.

The EDM superstar and Jessica Ledon went mudding on one of the islands near Ibiza ... just like Kate Hudson did a couple weeks ago.

Egor Tarabasov put himself back in the danger zone as far as Lindsay Lohan's concerned.

Her millionaire fiance hit up London's Chiltern Firehouse Thursday night -- the first time we've seen him out on the town since his blowout fight with Lindsay ... which led to her fleeing the country.

The Firehouse is like Craig's in West Hollywood -- celebs only go when they wanna be seen.

Lindsay Lohan's definitely showing ... mixed signals.

She's still hanging with friends on a yacht in Sardinia, Italy ... and this time we see what appears to be a bump ... of sorts.

You'll recall Lindsay went on a social media tirade -- and teased on Twitter she's pregnant -- after her blow-up with fiance Egor Tarabasov. Last time we saw her, Lindsay was smoking a cig, which is a major no-no when there's a bun in the oven.

News she's pregnant hasn't been confirmed ... and for all we know she coulda just been trying to stick it to Egor with a guilt trip. Interestingly enough ... sources tell TMZ Lindsay has privately told some family members she's preggo.

We'll anxiously wait for the second trimester.

Tinashe NEEDS a cameo in the new "Baywatch" movie looking as good as she does from a lifeguard tower.

Behold ... BOLT IS IN BRAZIL!!!

The fastest man EVER landed in Rio Thursday morning -- and greeted the fans with an "I am here" pose.

Bolt was greeted by fans and media -- but didn't say a word ... just gesturing with his hands before being whisked off in a private car.

Bolt's gunning for a "triple-triple" at the 2016 Games -- looking to win gold in all 3 of his events (100m, 200m and 4x100m) for the 3rd Olympics in a row.

But Team USA sprinter Justin Gatlin says he ain't gonna let it happen -- telling "TMZ Sports" he "guarantees" victory over his Olympic rival.

Should be fun!!!

Lindsay Lohan is getting by with a little help from her friends ... and a yacht captain doesn't hurt either when you're dealing with a broken engagement.

Lindsay popped up on board a boat in Sardinia, Italy on Tuesday, clearly looking to put some space between herself and fiance Egor Tarabasov. As we've reported, she fled London after the weekend blow up where she accused Egor of strangling her -- and police responded to their apartment.

LiLo admitted she made a mistake when she exposed the fight -- she called it "private matters" -- by blasting it all over social media. She says she's now taking time for herself ... all while staying in touch with her 7 million followers.

Eddie Murphy was a proud Beverly Hills pop at the premiere of his daughter Bria's new movie, "Amateur Night" -- proud of her and of his choice in women.

Ed was smack in the middle of what might be the hottest family photo op ever ... with current gf and baby mama Paige Butcher, Bria, his ex-wife, Nicole, and their other daughter, Shayne.

It's Bria's first feature film role. We don't know how the movie is, but it made this pic happen, so it's already worth it.

Try not to feel too bad if your modern fam doesn't look like this.
