Brad Pitt may not have had fiancée Angelina Jolie by his side for the premiere of World War Z in NYC on Monday night, but he had plenty of support from family. Angelina's dad, Jon Voight, made an appearance, as did her brother, James Haven, who brought his girlfriend, Ashley Reign. Brad's own brother, Doug, walked the carpet with his wife and three kids, even stopping for a photo op with Brad.

Brad is continuing the press tour for his zombie film after kicking off promotions overseas at the beginning of the month. He had Angelina close by during his London and Berlin events, and while she hasn't been spotted in NYC yet, she was the topic of conversation during an interview Monday morning. Brad told Good Morning America that Angelina is "doing great" after surgery and that they were "really surprised and moved by how many people are dealing with the same issue, or wondering about the same issue."

Mariah Carey wore a tiny white bikini while in Southern Italy with fellow recording artist Miguel today. Mariah and Miguel went swimming in the blue grotto, off the island of Capri, and hopped on a yacht after climbing out of the water. The duo have been spending time together since collaborating on the song "Beautiful," which was released last month and is a track off Mariah's highly anticipated 13th studio album. The album, the official title of which has yet to be released, will drop July 23.

Much of the hype may be due to Mariah's frequent Facebook, Twitter, and Instagram teases. While she announced the album release date on her personal accounts, Mariah also took to Instagram yesterday to share a personal snap of herself in blue waters with the caption: "A much needed splash after hours pon de mic singing for my beautiful lambily." In the post, she was addressing her fan base and revealed that her new work encompasses "three years of my soul." Mariah has returned to song-making after announcing last month that she will be not be returning for the next season of Fox's American Idol.

Man of Steel won the box office over the weekend with over $113 million and the biggest June opening to date. Meanwhile, the film's big stars are traveling around the world for further promotions. Henry Cavill, Russell Crowe, and director Zack Snyder walked the red carpet in Madrid today for another premiere, but leading lady Amy Adams did not attend the latest Superman showcasing. Amy did take in a big bear hug from Russell on Saturday, though, when they attended a photocall at the Taormina Film Fest in Taormina, Italy. They were joined by Henry as the group posed for photos against the idyllic countryside.

The three actors have been hard at work promoting their film, including last week's NYC premiere followed by a London showing on Wednesday as well. While in England, the cast battled with the rain, which nearly soaked a Valentino-clad Amy. Luckily, an assistant covered her up with an umbrella, which she giggled about while taking photos. Before the cast headed over to Italy, they taped an interview for The Graham Norton Show, which aired in the UK on Friday.

It was a weekend full of fun for Jessica Simpson and her fiancé, Eric Johnson, as they attended their pals Kathryn Sykora and Chris Hetherington's wedding at the Rancho Bernardo Inn in San Diego. The festivities kicked off on Thursday with welcome drinks, which were attended by Odette Annable and her husband, Dave Annable. On Friday, the fun continued with a BBQ and lawn games, where Jessica hung out with the bride and friends like CaCee Cobb. The guys, including Dave Annable and Eric Johnson, got together for a golf outing before the big event on Saturday, when Jessica and the rest of the guests tried to beat the heat by holding parasols during the ceremony. Jessica wore a similar black dress when she was a guest at a Pacific Palisades wedding in April.

The bride, Kathryn, is an interior designer based in LA, and had her bachelorette party in Las Vegas in May. She celebrated her September engagement with a bash in March alongside Jessica, CaCee Cobb, and Odette Annable. The groom, Chris, is a former 49ers teammate of Eric's, as well as a fellow Yale alum. Kathryn and Chris also attended CaCee and Donald Faison's wedding back in December.
