Porsha Williams hit the beach in Hawaii, showing off her bikini-devouring body -- and it might be more than her guy friend can handle.

"The Real Housewives of Atlanta" star was splashing around and taking selfies with the guy, while sucking down pineapple drinks. Sources close to Porsha tell us her sand mate's name is Todd, and they're celebrating his 40th birthday.

Get ready to judge Nick Viall's skills as the new 'Bachelor' -- we got the first photos and videos of him on a one-on-one date, and it looks like he just might avoid becoming a 4 time loser.

We got Nick in action with a blonde named Danielle. He's shooting the 21st season of the show right now, and this date went down Monday night in an entertainment area called Balboa Fun Zone in Newport Beach, CA.

The couple made a flashy arrival by boat with their names in lights. After that low-key entrance they rode a Ferris wheel, then sat down for a candlelit dinner. To make things really romantic, production hired 3 off-duty cops -- for about $1,500 -- to keep away curious fans.

Unclear if Danielle scored a rose or if Nick simply scored ... but dude needs a slump buster. He already struck out twice on "The Bachelorette" and once on "Bachelor in Paradise."

French Montana threw down stacks to bling out Iggy Azalea's digits ... TMZ has learned.

Sources close to French tell us the rapper dropped about $100k on the 7 rings he gifted her earlier this week. The rings were crafted by celeb jeweler Iceman Nick, who's also done some expensive bedazzling for a bunch of other rappers.

The purchase did the trick. Iggy gave French a shout-out on Instagram, after weeks of denying they've hooked up.

Iggy Azalea is warming up to French Montana ... with a little bit of ice.

Iggy posted a pic of her fingers enveloped in 7 diamond bands.

Iggy captioned the pic, "He told me pressure makes diamonds," and tagged the rapper and his jeweler, Iceman Nick.

Iggy's played coy up to this point, calling French a "friend," despite their makeout trip to Mexico a few weeks back ... but diamonds clearly make it official.

Adriana Lima's still going strong with New England Patriots star Julian Edelman ... who doesn't seem the least bit phased by her "date" with Ryan Seacrest.

Sources close to the Pat and the supermodel tell us EdeLima is still very much a thing. In fact ... the Victoria's Secret Angel was in Boston visiting the NFL star just a couple weeks ago. We're told she hung out with him and his friends, which is always a big deal.

We're told the visit was one week before Adriana was seen at an NYC restaurant with Seacrest, but Julian's not the jealous type ... and he believes she's just friends with the host.

Julian's focused on a different kinda victory right now -- he's busy prepping to be the backup QB for Thursday's game against the Texans.

Ryan Seacrest and Adriana Lima have been hanging out and even gone on a dinner date ... but we're told it's not a thing ... at least not yet.

The rumor mill was spinning hard again after Ryan and the supermodel were seen together a few days back after having dinner in Greenwich Village.

We're told the 2 struck up a friendship during the Rio Olympics ... where they both worked for NBC.

Stay tuned.

The divorce is officially underway ... 'cause Robert Griffin III has finally filed court docs looking to end his 3 year marriage to college sweetheart Rebecca Liddicoat.

Just last month, RG3 announced he had broken things off with Liddicoat -- the mother of their 1-year-old daughter -- and had moved onto a new lady ... Florida State track star Grete Sadeiko.

But now, we've confirmed the Cleveland Browns QB has filed the paperwork seeking to formally end his marriage. He filed on Sept. 7th in Texas.

Sources connected to the former couple tell us RG3 and Liddicoat are not on good terms -- and the divorce ain't gonna be pretty.

Robert doesn't seem phased -- he already got a tattoo of his new GF's name on his arm ... and has been posting love notes and couply pics of Grete on social media.

Nick Cannon fell in line with a new woman ... Chilli ... outside a Hollywood club, and made sure to follow her lead when the relationship questions started.

Nick and the TLC singer looked very cozy as they left Warwick nightclub and hopped in their ride -- but of course someone had to ask if there's any talk of marriage.

It's an odd question since Nick just told us he sucks at being married, but check out their response.

We don't know if they're a real couple, but we know they looked pretty damn hot together in his "If I Was Your Man" music vid.

Beware, Kyrie Irving ... Kenny Smith thinks a horrible breakup song should be written about you ... 'cause the ex-NBA star says Irving should be the next man up ... to date Taylor Swift.

Smith was out in L.A. when we wanted to know if it's time for the newly single T-Sweezy to give the NBA world a chance ... since it doesn't seem to be working with the actors and singers.

Kenny says YES ... and he has just the guy ... Cleveland Cavs star Kyrie Irving, who he says would be right up Swift's alley 'cause of where he's from ... and what he likes.

Nick Young definitely has a type ... hot musicians ... 'cause his new blonde date is an R&B singer who's done tracks with Meek Mill and Snoop.

Her name is Paloma Ford -- and she can sing. She also looks damn good in a bikini.

Paloma and Nick hit up Mastro's in Bev Hills together on Thursday night -- but sources tell us it was just a date ... they're not exclusive or anything like that.

Good news ... we're told the date went well.

Now that the fat lady has sung, people who were around Taylor Swift and Tom Hiddleston are talking about their relationship or lack thereof, and a lot comes down to timing.

You'll recall Taylor and Tom were first seen together at the Met Gala in early May, right before she broke up with Calvin Harris. There was hardly a breath between her breakup with Calvin and a major public display of affection between Taylor and Tom.

It may not be coincidence that Taylor and Tom were public about their relationship as Calvin's camp was spinning stories that she cheated on him. Some people familiar with the situation say Taylor's brand is so strong and clear ... it's better to make it appear her new relationship was serious rather than just a fling.

Something happened in June that was very un-Taylor-like. A photo agency got a pic that sure looked staged ... a pic on her Rhode Island estate showing Taylor and Tom kissing.

Taylor and Tom haven't been seen together since July 27. There was a lot of talk they had broken up but no one from Taylor or Tom's camp was talking for more than a month. Finally, Tuesday, the day after Labor Day and what people call the official end of summer, Taylor's camp leaked the breakup.

So the question ... how much of this was real, and how much was just image?

Drake's dad doesn't think anything's changed between his son and Rihanna ... and tells us everyone should slow down on any marriage talk.

We got Dennis Graham at Bootsy Bellows on the Sunset Strip -- surrounded by a flock of chicks, naturally -- and he shot down the prevailing thought that Drizzy's "settling down" with RiRi.

Check out the clip -- he even has a pretty funny take on his son getting inked up for Rihanna.

There's plenty of evidence lately to refute Dennis, but if he's right ... Drake could learn a few things from Dad, based on this clip.

Lionel Richie is always awesome and open, which makes this clip all the more revealing because he wanted to talk about anything BUT his 18-year-old daughter's relationship with Justin Bieber.

We got Lionel and Sofia leaving Pressed Juicery in Bev Hills, and he was happy to talk about all things citrus, but just watch as our photog asks if he's giving the Biebs his stamp of approval.

Sofia Richie doesn't need to wear Justin Bieber's shirts to prove they're a thing ... she just rocks his pants instead.

JB's gf was out in WeHo Thursday rocking a cropped top and official Purpose Tour sweatpants.

Even without Justin, Sofia's still reppin' her boo. Keeper material?

Justin Bieber used a date night with Sofia Richie to show off his serious skills on the drums.

Biebs was at Mozambique restaurant in Laguna Beach and joined a reggae band onstage recently, but not to sing ... he was there to beat the skins.

Sam Hunt and his on-again, off-again gf, Hannah Lee Fowler, are looking very ON while they show off their toned bods in Hawaii.

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.
