Gisele Bundchen frolicked around on the beach Tuesday in Costa Rica ... crawling around in the ocean with her adorable dog Lua.

In search of someone who could help protect him should Orlando Bloom strike again, Justin Bieber hung out Wednesday on a yacht in Ibiza with none other than Michelle Rodriguez.

There's nothing romantic going on here -- at least not in these photos -- and besides ... MRod's been hanging with a completely different skinny and often shirtless guy in Zac Efron.

If it came down to it, we feel pretty confident Rodriguez could take Bloom ... and Bieber ... and even Efron in a fight.

Miranda Kerr did NOT sleep with Justin Bieber after the 2012 Victoria's Secret fashion show ... so Miranda claimed at the time as did her lawyer.

Miranda's lawyer sent out a letter at the time rumors swirled that Miranda and Justin hooked up at a hotel after the show ... when she was still with Orlando Bloom. The letter calls such claims "false and defamatory."

We're told Kerr was as adamant as her lawyer at the time ... that she did NOT hook up with Bieber.

Apparently Orlando Bloom didn't buy the story. The couple separated the following year. And it's very clear from the story we posted Tuesday night ... there's beef between Justin and Orlando over Miranda.

As for Justin ... sources connected with the singer say he got all braggy when he talked about Miranda ... which of course does not necessarily mean he was telling the truth.

Miranda posted a photo this afternoon on Instagram of herself topless in a bathtub ... just in case you forgot what all the fuss was about.

8:30 AM PT -- We're getting different versions of what incited Orlando, and people are taking sides. One account is Justin extended his hand to Orlando, who refused it, and when Justin asked what's your problem ... Orlando mentioned Miranda. Justin then tried to walk away and that's when Orlando swung.

A second version -- Justin said something to the effect of, I had sex with your wife ... and THEN Orlando swung.

Orlando Bloom threw a punch at Justin Bieber early Wednesday morning in Ibiza ... and Justin fled the restaurant -- this according to 2 eyewitnesses.

The eyewitnesses tell TMZ ... Orlando was in Cipriani restaurant which was packed with celebs, including Paris Hilton, and Diddy.

You don't see Orlando swing, but the eyewitnesses tell us that's exactly what happened. We're told Justin ducked the punch. That's where the video starts and you hear Justin scream, "What's up bitch?"

We're told when Bieber left the crowd applauded.

The backstory is almost legendary ... Justin partied with Orlando's then-wife Miranda Kerr after a 2012 Victoria's Secret fashion show in NYC and they got very VERY close. And in April of this year, Orlando was hanging out with Justin's on-and-off GF Selena Gomez. So the bad blood is flowing.

Hours after the fight ... Justin threw gasoline on the fire by posting -- then quickly deleting -- this pic of Miranda.

The sister of "Big Brother" contestant Jocasta Odom is tearing cast member Frankie Grande to shreds ... for saying Jocasta "can kill herself."

Frankie's back stab stung hard ... because Jocasta -- a pastor -- just performed a memorial service for his recently deceased grandfather.

Maranda Chelsea, Jocasta's sis, tells TMZ, "It was an ignorant statement and the little respect I had for him just went out the window." And the parting shot, "It shows the lack of maturity he has."

Miranda isn't the only one pissed off -- so are the fans ... @JrAguja1997 tweeted "I don't f**king care if your sister sings good, you're a s**tty person Frankie. Calling Jocasta to kill herself. Argh."

"The View" producers will give potential replacement co-host Lauren Sanchez her shot at one of the coveted seats when she sits in for Wednesday's episode.

TMZ has learned Sanchez got the call last week, and was told she would be co-hosting with Whoopi Goldberg, Jenny McCarthy and Sherri Shepherd.

Our 'View' sources tell us producers will be watching for Sanchez's "chemistry" with Whoopi -- which makes sense since she's the only one who will be back next season.

As TMZ first told you ... producers are on the hunt for 2 new co-hosts -- one conservative and one Latina. Sanchez -- a former news anchor and 'Extra' host -- was nearly hired in 2000, but they went with Lisa Ling instead.

As Barbara Walters herself put it, Lauren was "thiiis close" to getting the gig back then.

Scott Disick returned to the scene of the crime last night with a wine glass in hand as he partied with French Montana and Fat Joe at J.Lo's 45th birthday bash.

Interesting that Lord D posted the pic himself. We can't tell what's in the glass, but it seems Scott has gotten over the night of severe boozing in the Hamptons about a month ago that sent him to a hospital with alcohol poisoning.

As we told you ... that incident got Scott on the wagon -- sources told us he hadn't had a drink since.

Selena Gomez and Cara Delevingne are back from their sun-drenched trip to St. Tropez and when they arrived at LAX Thursday ... they received a welcome home crush.

The pair, now famously photographed hanging on a yacht in their bikinis and showering together, are the hottest "couple" around these days ... even if they aren't ... ya know. Selena was nuzzling with a muscly guy during the trip.

Anyway, they were bombarded with questions about their friendship, but they remained tight-lipped.

"Big Brother" producers broke the news to Ariana Grande's brother late Wednesday that his grandfather passed away -- and the whole 'BB' house is rallying around him.

TMZ broke the story earlier today ... Frankie Grande's grandpa died on Tuesday, but Ariana obeyed his final wish -- to let Frankie continue on 'BB" despite his illness.

But this evening producers passed a note to Frankie from his family ... which revealed the sad news.

According to bloggers watching the 'BB' live feed -- Frankie broke down in tears and shared the news with everyone else in the house. Some of the other house guests are crying too.

Frankie's grandfathers death has hit Zach. Zach is crying in the lounge alone. Zach: "This sucks!" #BB16

"Big Brother" is now keeping a deep secret -- something that could derail the show if revealed too soon -- and it involves the death of one of Ariana Grande's relatives.

Ariana's grandfather died Tuesday. He's also the grandpa of Ariana's brother, Frankie Grande, who's a contestant on "Big Brother."

It seems just before he died the grandfather knew Frankie might bail from the show if he found out, so one of grandpa's last wishes was to keep his death a secret from Frankie.

Ariana was chronicling her grandpa's illness ... recently posting pictures with him in the hospital. But Frankie never saw them per the rules of the show.

Ariana made her grandfather's wishes clear, tweeting, "asked grandps last week if he wanted us to pull frankie off bb & he said "no way! he's gotta play the game even tho i don't understand it"

It seems from the "Big Bro" live feeds ... Frankie is still in the dark over his grandpa's death.

7:00 PM PT -- Producers just told Frankie about the death.

Naya Rivera's marriage to actor Ryan Dorsey came out of nowhere for everyone, except Naya -- who actually co-opted a lot of the ceremony from her planned wedding to Big Sean ... including the date.

Rivera and Dorsey tied the knot in Cabo San Lucas over the weekend. The longtime friends began dating right after Rivera broke off her engagement to rapper Big Sean in April.

According to our sources, the wedding date -- July 19 -- was the exact same date Naya and Sean were supposed to tie the knot. We're told Naya picked the date back in October when she and Sean got engaged.

The similarities don't end there ... according to reports, Rivera was married in a Monique Lhuillier gown -- which our sources say is the same designer of the dress Sean bought for Rivera for their wedding.

One more thing -- Rivera never gave back Sean's engagement ring, according to our sources. However, we don't know if she found a way to re-purpose that.

Mazel?

Ryan Dorsey's dad, Arnold, tells TMZ ... the date of the wedding might have been the same as the Rivera/Big Sean wedding ... but it also happens to be Dorsey's birthday.

Arnold says he found out about the wedding six weeks ago and while he was initially surprised, he said, "We didn’t question him. We are very happy for him. We trusted them and want what they wanted."

Arnold also said the wedding was small, about 12 people total, and consisted of Naya’s family and Ryan’s family.

Cesar Millan couldn't stop one of his gigantic clients -- a Great Dane -- from attacking a neighbor during a training session yesterday ... TMZ has learned.

Sources tell us the 'Dog Whisperer' star was walking a group of dogs, including the Great Dane, near his home in Studio City, CA -- and none of the dogs were leashed.

We're told one of Millan's neighbors was out walking his own dog ... and when the neighbor reached out to let the Great Dane sniff his palm ... the dog suddenly bit the man's hand and forearm.

We're told Cesar followed the man to the hospital where he was treated and released. Unclear, at this point, how badly he was injured.

A rep for Millan confirmed the attack, and says Cesar was walking a "troubled dog" as part of its training, when it got "spooked by a neighbor." The rep added, Cesar is still caring for the dog.

We don't know yet how big this dog was -- but adult Great Danes range from 100 to 120 pounds.

A source close to the victim tells us "he's healing," and is following up with a physician today.

It's Selena Gomez's birthday, but we're getting the gifts -- behold Selena and Cara Delevingne showering ... together ... in bikinis ... on a yacht.

Our favorite new BFFs made the sexiest pitch for water conservation while continuing SG's bday week celebration in St. Tropez -- but this time they had company in the form of Tommaso "Tommy" Chiabra.

In addition to ruining an otherwise perfect moment ... Chiabra has been seen with Gomez a lot recently, and has also been linked to 'Gossip Girl' Jessica Szohr.

Hate him. Love the pics.

Notorious friender Cara Delevingne has a new gal pal ... Selena Gomez, who celebrated her 22nd birthday with Delevingne aboard a yacht in St. Tropez.

Forget posing for a pic with model Tanz Watson, if Selena really wants to make Justin Bieber jealous ... this is how you do it.

Sofia Vergara and her significantly younger new man Joe Manganiello are officially out of the cage.

The 37-year-old "True Blood" star was out and about this weekend in Studio City showing off his prize catch ... five years his senior.

This is nothing new for Sofia, who's just coming off a similar situation with boy toy Nick Loeb ... they were together for almost 4 years, got engaged and split up last May.

We're not worried about Joe, of course ... if anyone can keep a cougar at bay, it's wolf man.

Happy hunting, Joe.
