The Desperate Housewives star, who was wearing an Emilio Pucci dress with a plunging neckline, was posing for pictures with her hairstylist Ken Paves when her right boob made a surprise appearance.
Longoria seemed to be trying to rearrange her dress for the snaps, and as she bent down to untangle herself, the floor-length gown gaped revealing her nipple.
According to The Sun, Eva was 'unaware' of the wardrobe malfunction, which unfortunately for her, was captured on camera.
Back in 2011, the 37-year old famously flashed a nipple during an appearance on David Letterman's chat show after wearing a jacket with no bra underneath.
