You know it's summer (or 1999) when the Hilton sisters make news in South Beach. Nicky Hilton and her bachelorette party stayed at the 1 Hotel South Beach. The group arrived on Thursday and was joined on Friday by sister Paris, who flew in from Ibiza. Among those in the gaggle: cousins the newly wed Brooke Brinson-Wiederhorn and Whitney Davis, daughters of back in rehab Real Housewives of Beverly Hills cast member Kim Richards, and Farrah Aldjufrie, daughter of RHOBH's Kyle Richards.

On Saturday, Paris helped her sister celebrate her bachelorette party in South Beach at Wall Miami. The pair showed up at nearly1 a.m., donning bachelorette sashes, a crown for Nicky and bright pink cat ears for Paris. The group had a large table filled with Belvedere Vodka and champagne and were joined by a large group of friends including New York Socialite Dori Cooperman and Allison Melnick. The group held blow up glow sticks that said "Hilton Bridesmaids," which revelers held in the air throughout the evening. The gang celebrated with a massive bottle parade and oversized bright pink cake in the shape of an engagement ring box (ring included). Never one to forgo the attention, the party also served as Paris' new single debut, but the heiress did dedicate the song "High Off My Love" to her sister "the future Mrs. Rothschild," who later joined her in the DJ booth.

The group of girls held their Hilton Bridesmaids inflatable sticks and danced in the DJ booth while Paris kept the crowd going all night long. At some point over the weekend, the sisters were also at Story and on nightlife mogul David Grutman's 55 foot custom Van Dutch boat which took them to Seaspice. Overheard by one of our spies, the sisters waxing philosophical on Caitlyn Jenner, saying that while they are no longer as close as they were with the Jenner klan, they are so "proud of her and think she is so pretty." The sisters also wanted people to know that this was a very "tame" bachelorette party. Whew. Good to know.

Former reality show personality Audrina Patridge hosted the Klique App Miami launch party Saturday at The Raleigh Hotel. After dancing and mingling with guests all night long, Patridge and friends headed over to Cleo South Beach for a late dinner. During dinner, the ex Hills cast member participated in the restaurant's plate breaking ceremony. Following dinner, they headed over to Wall for the Hilton hootenanny, drinking, yup, Belvedere all night long. We're told that although Patridge wanted to sit with the sisters and their crew there, she was not allowed into the VIP area. The horror! On Friday, Patridge and a friend celebrated a birthday over wine and tapas at Ball & Chain where they took some salsa lesson's on the Little Havana hot spot's Pineapple stage.

Perhaps Patridge could have traded places Entourage actor Rhys Coiro, also at WALL, who, when asked if he would like to join the Hilton hootenanny, he kindly said, "No, thanks."

Also in town from Entourage: Emmanuelle Chriqui, seen Sunday at Hyde Beach celebrating her cover of Ocean Drive magazine.

Spotted over the weekend at the Boca Raton Resort were Kate Upton and William H. Macy, shooting a scene for Macy's latest directorial project, The Layover, a “road trip sex comedy” starring Upton and Lea Michele.

Marriott officially opened the AC Hotel Miami Beach Sunday with a big party hosted by fashion photog Nigel Barker and Dutch architect and shoe designer Rem D. Koolhaas. The hotel's owner, Robert Finvarb, presented a promised gift of the work of Chuck Ramirez to Pérez Art Museum Miami interim director Leann Standish. As an extension of the property’s contemporary art collection, which is curated by Miami gallerist Dina Mitrani, the work by Ramirez from his Lost and Found series, will be shown in the hotel and later become part of the PAMM collection.
