Harry Styles is either an honorary family member to Cindy Crawford and Rande Gerber ... or just a great drinking bud.

The trio did lunch -- with Cindy and Rande's daughter Kaia -- at one of their restaurants ... Cafe Habana.

No word what was on the agenda for this sit down, but 22-year-old Harry's been in with the 50-something Gerbers for a while. He scored a few boxes of Rande's Casamigos tequila for his birthday in January. Maybe the kid wants a piece of the agave game, or maybe he just needs a fresh case.

Rob Kardashian is so out of his shell now ... he's even passing up the full service pumps during his outings with GF Blac Chyna.

Rob opted for pumping petrol himself Wednesday afternoon in Bev Hills, and did it with a huge smile. In addition to being back into the public eye, he's also back in with his family.

Yep, all signs point to Rob having a very happy 29th birthday on Thursday. Just lay off the green beer, bro ... not good for the diet.

Julianne Hough and her 3 sisters are having a kick ass Mexican vacation -- bikinis, sun, cervezas and ... projectile vomiting off a boat!

The former "Dancing with the Stars" judge and pro is down in Cabo San Lucas on a family girls trip -- Mom's there too -- and they all set sail Tuesday. Looked like a ton of fun at first ... and then las hermanas y madre turned their stomachs inside out.

Unclear if the illness was booze or wave induced, but Julianne comforted everyone by making sure to capture their puking on her iPhone.

Viva Mexico!

50 Cent got framed by a photo agency, literally ... he was framed up in a shot with a Mercedes-Benz dealership, making it seem like he was new car shopping but that just ain't the case.

Here's the deal ... the photo agency, AKM-GSI, that was peddling the Fiddy pics and video included a caption that went on about the financially-challenged rapper scoping out an expensive ride. Seemed weird, considering 50 Cent's bankruptcy issues.

Well, turns out the agency was wrong. 50's people tell TMZ ... instead of spending wildly, he was talking biz with his agent -- discussing his hit TV series "Power." The agent's office is in the same building as the Benz dealer, which is how the pap got the shot.

AKM-GSI has apologized for the error.

So, the bankruptcy judge can chill -- 50 Cent was actually making cash in Bev Hills, not blowing it.

Heather Locklear and Richie Sambora's little girl is ... NOT a little girl anymore -- Ava Sambora is now a full-fledged model.

18-year-old Ava did a photo shoot on the beach in Malibu -- and clicking through this gallery should answer all your questions about how DNA works. She's kind of a genetic sure thing -- and probably a great guitarist too.

Richard Simmons says his maid is not holding him hostage, but judging by this pic she's definitely holding down the fort.

Simmons called BS on reports his longtime housekeeper, Teresa Reveles, was keeping him isolated from friends and business associates. Teresa was all business Monday as she kept guard at Richard's Hollywood Hills house.

The biggest names from Hollywood and Washington, D.C. descended on Simi Valley Friday morning for Nancy Reagan's funeral.

Among those honoring the former First Lady ... Michelle Obama, President and Mrs. George W. Bush, Hillary Clinton, Arnold Schwarzenegger, Larry King and more.

The usually flawless Jennifer Lopez finally made a questionable wardrobe decision during a recent taping of "American Idol."

The color screams failed bridesmaid dress -- and it's way too loose on her -- but thankfully the curves underneath are still 100% Jenny from the block.

Elin Nordegren's tycoon boyfriend Chris Cline has earned his stripes with Tiger Woods' ex-wife ... in a BIG billionaire way.

The two jetted off for a ski trip to St. Moritz, Switzerland -- it's where the rich go to ski -- and looked real cozy on the mountain ... after arriving by helicopter!

36-year-old Elin met Chris, who's 21 years older, when she started building her post-divorce, mega-mansion in Palm Beach ... right next to his beachfront palace. They split in 2014, but got back together late last year.

You know what they say -- couples who ski together, do NOT golf together ... especially with their exes.

Carrie Underwood is celebrating her 33rd birthday while on the road, but a fan made sure she didn't miss out on the festivities.

Carrie was leaving a "BBC Breakfast" interview Thursday in London when a fan surprised her with a cake outside the studios. She seemed to love the sweet gesture ... but chances the country superstar actually bit into it are slim.

As they say ... never take candy from a stranger. Same goes for cake or pie.

Here's Nicole Murphy at some TV premiere event in West Hollywood ... where we guarantee no one was talking about the show once she arrived.

It's like when a wedding guest looks better than the bride.

She's about to be suspended from the court ... but Maria Sharapova still has the beach -- and today, she grabbed her racket to hit some balls on the sand.

Despite the fact Nike suspended her deal in the wake of her failed drug test, Maria was sporting Swoosh pants and shoes on an L.A. beach Wednesday afternoon ... with a smile on her face.

Maria admitted she tested positive for a banned substance at the Australian Open back in January -- and the International Tennis Federation has announced she'll be provisionally suspended starting March 12th.

In the meantime, might as well get a tan right?

Jason Derulo and Daphne Joy did their own version of "Baywatch" ... flaunting their ridiculous bodies while vacationing in Mexico.

The couple hopped on an ATV, tried their hands at surfing and frolicked on the sand outside Casa Aramara, Joe Francis' celeb-friendly estate in Punta Mita.

Bradley Cooper and his supermodel girlfriend Irina Shayk aren't hiding their relationship anymore ... in fact, they're swapping spit for all to see.

Bradley and Irina finally made their red carpet debut as a couple Tuesday night at the L'Oreal Red Obsession Party in Paris.

It's been a long time coming ... they first began seeing each other last May, but tried to keep things on the hush hush.

Mazel.

Some people will do anything to score Rosie Huntington-Whiteley's phone number.

Okay, we doubt that's what actually happened, but the stunning model did get rear-ended Tuesday in Beverly Hills. The accident appeared minor ... especially considering the size of her SUV, compared to the other car.

Rosie exchanged info with the other driver before driving off, but we're guessing her personal cell was not part of the transaction.

Worth a shot.

Rob Kardashian and Blac Chyna want you to believe he's in the throes of a crash diet, but get a load of his carbo-load and the booze to help wash it down.

Rob and Chyna hit up Benihana in Encino for lunch Tuesday ... and our Far East sources tell us they wolfed down a "whole bunch of sushi," as they sipped on a couple rounds of sake and mimosas.

Rob's had issues with substance abuse, and Chyna's fresh off a daytime arrest in Texas after getting wasted at the airport.

That said ... it looks like Rob's losing a bunch of weight.

The Benihana diet. Who knew?
