Happy 50th birthday, Caesars Palace! The Las Vegas institution hosted a celebratory weekend in honor of its milestone.
Festivities included a massive birthday pool party, complete with a five-tier cake, champagne toast and firework extravaganza, hosted by Gordon Ramsay on Aug. 5, and an extraordinary gala headlined by Tony Bennett, Jennifer Lopez, Howie Mandel, Donny and Marie Osmand, Matt Goss, and The Righteous Brothers the following evening.
During Saturday's soiree, Calvin Harris was one of the honorees presented with the Special Icon Award in recognition of his time as OMNIA Nightclub's headliner. Even cooler? The 32-year-old DJ/producer got to hang with the iconic Mr. Bennett!
Harris' fellow honorees, who were all recognized for making significant contributions to Caesars, included Ramsay, Celine Dion, Elton John, Jerry Seinfeld, the Knievel Family, Larry Ruvo, and Gary Selesner.
That same evening, Charlotte McKinney was also partying in Sin City, but for a very different reason -- her 23rd birthday! Rocking an off-the-shoulder velvet mini, the Baywatch star celebrated at the Encore Beach Club and Intrigue Nightclub at Wynn Las Vegas – pink-and-white floral birthday cake and all.
On the opposite coast, Malin Akerman bonded with fellow actresses Emmanuelle Chriqui, Arielle Kebbel and Jamie Chung during Women's Health's fifth annual Party Under the Stars celebration at the Bridgehamption Tennis & Surf Club on Aug. 6. Fellow attendees included Lauren Bush Lauren, Katie Lee, Kristin Taekman, Kelly Kiloren Bensimon, and Taryn Manning, who starred as guest DJ for the night.
The Billions star is mom to a 3-year-old son, Sebastian, and she admitted at the event, which kicked off the magazine's nationwide RUN 10 FEED 10 program, that even though she eats everything her child doesn't finish, "which is like chicken fingers and fries," she still manages to keep a healthy lifestyle.
"I've always been health-conscious," Akerman, 38, explained. "I always like to feel good more than anything... trying to get some sort of workout in. I've got to be clear-headed. I've got to be ready for my son and get my sleep."
"I'm a very good cheater as well," she added. "I need chocolate every day or else I don't think I could live. It's like oxygen."
Chriqui seconded the notion of trying to be conscious of the food she's putting in her body. "I just aim to live a really health life anyway," she said. "I'm an environmentalist -- I love supporting organic food and just doing things in a way that's nice for the planet. That's my goal in almost everything that I do."
While many celebs spend the weekend at soirees, a few chose to go a little more low-key. Real-life couple and former Manhattan Love Story co-stars Jake McDorman and Analeigh Tipton took in a screening of Speed at Cinespia in Los Angeles on Aug. 6. Also in attendance was outdoor movie lover David Beckham and his sons, as well as Austin Stowell, who was joined by his dad and brothers.
Others hit the stage, including OneRepublic, who performed an exclusive concert at New York City's Irving Plaza on Aug. 5 to celebrate Moto's new Moto Z Family and Moto Mods.
Lionel Richie's set at the 2016 Outside Lands Music and Arts Festival at Golden Gate Park in San Francisco, California, on Aug. 7 was anything but private -- it was livestreamed on LiveXLive. The iconic singer was one of the headliners on day three of the fest.
And Justine Skye sang at NextRadio App's Summer Pool Series at The Mondrian Sky Bar in West Hollywood, California, on Aug. 7. Kid Ink also performed at the outdoor fete, where attendees like Kendall Jenner, Hailey Baldwin, Shaun Ross, and Drew Mac got to enjoy NextRadio’s signature Blue Oasis cocktail, food by Ivory on Sunset, manicures by LVX and makeup touches or flash tattoos from GlamSquad.

…while Tamera Mowry shared her love of all-natural beauty products with her 1-year-old daughter, Ariah. Don’t worry, though -- the tiny tot wasn't cleaning her face quite yet. "Can't believe@DickinsonsWitchHazel has been a favorite for 150 years and I am just finding out?!" The Real co-host wrote on Instagram on Aug. 5. "Natural and clean products that are great for my skin, yes please! When Ariah's older, she can actually have some Dickinsons on her cotton ball."
CaCee Cobb was all about shopping, taking her very mobile 1-year-old daughter, Wilder Frances, to Stride Rite for some new shoes.

Meanwhile, Debra Messing enjoyed lunch with two other women at Il Piccolino in West Hollywood, California, on Aug. 9, where they munched on red grapes.
