The curvaceous diva, who became a mum in January, strutted her stuff in a skin-tight, red costume with cut out panels – and there wasn’t an ounce of baby fat to be seen.
Her trademark tumbling locks flew into the air as she belted out smash hit Single Ladies on the first of her four night stint at the Revel Ovation Hall in Atlantic City.
And she rocked the showgirl look in a silver fringed bra and hotpants, with shocking pink stilettoes and fishnet tights.
The costumes, which also included a sheer black bodysuit with a fringed tail, were designed by London-based Ralph & Russo and, together with the dancers’ outfits, boasted 500,000 Swarovski Crystals.
The singer, whose last performance was at the MTV video awards last August, told the audience: “I gotta say, it feels so good to be back home on stage.”
She also showed a brief clip of herself cuddling her baby daughter on the video screen behind her during one song.
The 30-year-old star rattled through her hits, including Crazy In Love, If I Were A Boy and Halo, to the delight of the 5,000 strong crowd – which included best pal and Destiny’s Child bandmate Kelly Rowland.
She paid tribute to disco queen Donna Summer with her own song, Naughty Girl, which features a rift from Love To Love You Baby.
And she remembered soul diva Whitney Houston with a cover of I Will Always Love You.
Cheering from the wings was her biggest fan, husband Jay Z, who took to Twitter to show his approval.
He wrote: “I’m gonna say this and then I’m gonna end mine. Beyonce is the best performer in the world. Period.”
Jay-Z, we can see your Halo.
