It’s been nine months since Beyonce last performed for her adoring fans.Taking to the stage in New Jersey last night for the first time since giving birth to daughter Blue Ivy, it appeared her time out for motherhood hasn’t affected her stage presence.Showing off her post-baby curves in a showgirl-style, fringed bralet and tiny shorts, the 30-year-old wowed the sold-out crowd on the first of a three-night stint at the Revel Resort & Casino in Atlantic City. Supporting her from the wings was her rapper husband Jay-Z, who recently returned from the London leg of his Watch The Thrones tour with Kanye West.Under his Twitter name Mr Carter, he wrote: ‘I’m gonna say this and then I’m gonna end mine. BEYONCE is the best performer in the world. Period.’  The gig marked Beyonce’s first concert since giving birth to their daughter Blue in January, following her last gig at the MTV Video Music Awards last August - the same day she confirmed her pregnancy.Speaking to the 5,500 fans at the Ovation Hall in the Revel, she said: ‘I gotta say, it feels so good to be back home on stage.’However, she didn’t bring up her new life as motherhood too often, except for a fleeting glimpse of Beyonce cradling her daughter in a video montage on the screen behind her.Her sexy costumes were custom-made by London design house Ralph & Russo, who used 500,000 Swarovski Elements crystals to create the look.dailymail.com
