Beyoncé wowed a crowd of about 18,000 people last night in LA at the Staples Center during her most recent Mrs. Carter Show World Tour stop — and that crowd happened to include plenty of famous fans. We spotted many celebrity couples in the boohoo VIP lounge, including Kate Mara and Max Minghella, who sipped champagne together in a corner booth, as well as Zoe Saldana, who attended with her new husband, Marco Perego, and her sister. Several stars also rolled to the show solo or with friends, including Molly Sims, Victoria Justice, and Kellan Lutz, and a couple of lucky ones had the chance to attend a meet-and-greet with the star after her show. Jessica Alba met Beyoncé backstage with a group of female friends and tagged their photo #queenb #beauty.
Beyoncé's dynamic show included more than a half-dozen costume changes and a set list full of her biggest hits, including "Single Ladies" and "Baby Boy." The singer also worked in a cover, announcing to the crowd: "I dedicate this song to Paul Walker" just before launching into a rendition of Whitney Houston's "I Will Always Love You." Beyoncé's performance landed on the eve her husband Jay-Z's 44th birthday. The couple, along with their daughter, Blue Ivy, are in LA not only for her tour, but also for Jay's. He'll follow Beyoncé on the Staples stage next Monday for the LA date on his Magna Carta tour. The rapper is also reportedly thinking about new beginnings as he embarks on another year. Jay Z and Beyoncé are going vegan — at least temporarily — which he announced on his blog yesterday. Jay said a friend inspired him to try the new approach to eating and that the effort was not just physical. "There's something spiritual to me about it being my 44th birthday," he wrote, "and the serendipity behind the number of days in this challenge; 22 (2+2=4) coupled with the fact that the challenge ends on Christmas Day . . . It just feels right!"
