Beyonce knowles almost flashed onlookers with more than they bargained for as she left Rihanna's 3rd Annual Diamond Ball in New York last night.
The singer put on a very busty display in her plunging silky green dress, which looked as though it could barely contain her ample assets.
Her generous cleavage took centre-stage as she cosied up to husband Jay-Z and fellow pop star Rihanna at the glamorous bash.
While her buxom bosom stole the spotlight inside the event, when she left the Cipriani Hotel she almost flashed everything as her thigh-high split dress fell out of place.
Beyoncé could be seen grappling with her frock as she exposed her black, lacy Spanx, which only covered her right leg.
But despite her embarrassing wardrobe malfunction, the 36-year-old seemed completely unfazed by the mishap and flashed a huge grin at waiting photographers.
The mother-of-three completed her glamorous attire with a pair of towering black sandals and dazzling diamond earrings.
Her blonde locks were styled in tight curls while she sported a slick of pink lipgloss to complement her radiant complexion.
Meanwhile, Rihanna put on an equally busty display as she slipped into a boob-baring black gown, which featured a corset-style top.
The flowing frock featured a mini-skirt at the front and a long train at the back, which allowed the Work singer to flaunt her toned pins.
She drew even more attention to her exposed bust with a head-turning diamond necklace and a matching bracelet.
Her dark locks were styled in cascading curls and sported bronze smokey eye make-up and a slick of n-de lipstick.
