When you're Sofia Richie and your dad is Lionel Richie and your boyfriend is Scott Disick and your bestie is Kylie Jenner, this is what your 21st birthday celebration looks like!

It starts with a private jet to Las Vegas, a high-roller penthouse suite at the Wynne Resort & Casino, then a pool party in your honor with life-sized cardboard cut-outs of YOU, DJ'ing by Alesso at the Encore Beach Club, then on to XS Nightclub with a performance by The Chainsmokers.

Then, at 4:45am, you post to your Instagram Story, "And it’s over people," as you board your private jet back to LA wearing boyfriend Scott's Talentless sweats like the ones you've gifted to your ride-or-dies who braved Vegas with you to celebrate 21.

A rescheduled concert date after Mick Jagger's emergency heart surgery, the Rolling Stones are still alive and kicking! Though memories may be fading a bit, they still know how to start up a concert with "Start Me Up." Jagger said to the crowd on Thursday night, "It’s been 25 years since we played the Rose Bowl! And it’s been 55 years since we first played L.A.!” Uh ...

Fellow aging rockers were in attendance including Billy Idol, with his kids Willem Wolf and Bonnie Blue, Bruce Springsteen, Motley Crue's Nikki Sixx and others. Robert Downey, Jr. opening the gig with this scientific tribute -- announcing the nearby Jet Propulsion Lab had named a rock on Mars after the band: "While landing on the red planet’s surface [the InSight spacecraft] displaced a rock that rolled a fair distance in view of its onboard cameras.” Get it? Rolling Stone. Jagger followed: "I want to bring it back and put it on our mantelpiece."

And so they roll on ... how much longer Jagger, Richards, and gang will be able to deliver as they roll into their late 70s is anyone's guess for for now, the show goes on!

How many outfits can a girl wear in one day?! If you're Hailey Baldwin, at least 4 or 5!

The model wore an adorable lime green gingham-checked ensemble with neon Off-White Nikes on the way in and a bright peach oversized blazer with baggy jeans and a cinched, belly-bearing top. Both cute!

Hailey's been ramping up visits to her stylist's showroom now that she and Justin Bieber have set their wedding date for Sept. 30. Obviously there are lots of fashion moments that'll happen - travel to South Carolina, rehearsal dinner, days of golf and being on the lake, of course the wedding dress and reception dress and then the day after. So much to think about!

Meanwhile, Hailey and bestie Kendall Jenner were seen boarding a private jet just after these photos were shot -- believed to be on their way to Idaho's Gozzer Ranch where both ladies vacationed separately recently and where it's believed they're celebrating Hailey's bachelorette!

Talk about sexual tension! Kourtney Kardashian isn't afraid to party with her exes and look HOT while doing it!

The mother-of-three hit up The Nice Guy, on Friday, with sisters Kylie and Kendall Jenner AND with ex-boyfriends Younes Bendjima and Luka Sabbat also cozying up to the clan in a VIP booth! Awkward? Nah! This lady's used to run-ins like this, as the insular family keeps their friends close and their exes closer!

Kourt sported a tight dark-brown tank with matching leather pants and strappy heels -- one of her favorite go-to looks.

The group was there to celebrate the birthday of Kendall's podcast partner Daniel Chetrit. Speaking of Kendall ... HER ex, baller Ben Simmons was there, too!

Kylie seemed to be the only one without a former love interest in attendance (but who knows, right?!), as she kept it on the DL for a rare night out with pal Stassie Karanikolaou, wearing a dark brown D&G mini-dress (is this the new on-trend color?) with chunky white sneakers, Stassie looking like her fashion twin in a black hoodie, black biker shorts, and matching chunky white sneakers.

But why hid, Ky?! We need to see your pretty face!

It must be love! Scott Disick tied a big red bow around a $200,000 Aston Martin and gave it to his lady love Sofia Richie for her 21st birthday today!

The 36-year-old gifted his just-legal girlfriend the shiny black with camel leather interior ride on this monumental event -- the day she can finally LEGALLY drink those glasses of rose, Champagne, and prosecco that she sipped all summer in Italy!

The little Richie girl also posted to her Instagram story that she received a new Range Rover, too -- maybe that was a present from dad Lionel. He and Scott should have coordinated on their gift-giving! How embarrassing that they both gave the same present!

We hear wedding bells! Actually we don't, but some other media outlets do and we're gonna pull alllll the info together and give it to ya here!

• Justin and Hailey sent out Lichtenstein-inspired wedding invites with a comic-like drawing of the two stars for a Sept. 30 wedding date in South Carolina!
  
• The couple will host their nuptials at the Montage Palmetto Bluff in Bluffton, SC.
  
• The resort has Sommerset Chapel (above) on the property, specifically for weddings.
  
• Jailey were spotted at the resort Aug. 12 and they own Montage residences in Laguna Beach and in Beverly Hills.
  
• The entire resort is fully booked Sept. 29 and 30 (which happens to be the Jewish holiday of Rosh Hosanna).

Guests will stay at the Montage which features its own lake, a Jack Nicklaus Signature Golf Course, a nature preserve and even two of its own villages with shopping and dining options.

The ceremony will be "super small" with fewer than 100 guests, a source tells Us Weekly. Check out the gallery below to see all the amenities of this beautiful property where Justin and Hailey will finally make their love official with their family and friends!

Bethenny Frankel tied the knot?!

Just a day after announcing she's leaving the hit Bravo series Real Housewives of New York, the star of the show (let's be honest) Tweets that she had to leave because she's the only castmember who's MARRIED???!!!

This morning, the Skinnygirl founder Tweeted: "To my NY hwives: GO GET EM! I had to go since I’m the only one that is actually married...that’s how crazy this ride is. You are all amazing, beautiful and strong. Spread your wings and fly! Xoxo." So girlfriend went and married her boyfriend Paul Bernon!

Bernon's a film producer and he's in real estate back east in Massachusetts; he's divorced with kids like Bethenny, and he's a Boston native. The pair have been dating since October.

Let's not forget, Bethenny's ex-boyfriend Dennis Shields died of a drug overdose just a year ago and he'd reportedly proposed to Frankel in April.

It was just Wednesday that Frankel announced she's leaving HER show "to move on and focus on my daughter, my philanthropy and my production partnership with Mark Burnett." So she won't be leaving TV -- thank GOD! -- and her new endeavors will be as a married woman, apparently! Congrats, Bethenny and Paul!

To my NY hwives: GO GET EM! I had to go since I’m the only one that is actually married...that’s how crazy this ride is. You are all amazing, beautiful and strong. Spread your wings and fly! Xoxo @ramonasinger @CountessLuann @TinsleyMortimer @SonjatMorgan @dorindamedley

Worship time is family time! Justin Bieber and Hailey Baldwin must be feeling broody, hanging with their pal and mentor Hillsong pastor Carl Lentz and his family. Lentz has three kids -- Roman, Charlie, and Ava -- and we all know Jailey have been waiting for just the right moment to start a family ... which may be after their supposedly-planned wedding ceremony next month!

Hailey looked hot in an animal-print bustier and jeans while Justin wore a tie-dye tee to church. Hey, Hillsong is dressed-down, y'all -- Pastor Lentz is known for his hype street style on stage at church and check out HIS t-shirt with holes in the back!
