Eva goes commando at Cannes. What could possibly go wrong?

A SKY-high split, a drizzly day and an absent pair of knickers was not a winning combination for Eva Longoria at the Cannes Film Festival.

The Desperate Housewives actress suffered a disastrous wardrobe malfunction while trying to navigate her way along the rain-soaked red carpet on Saturday night.

Opting for a backless pale green Versace number with a dangerously thigh-high split, Longoria hitched up her floor-length frock and accidentally revealed far more flesh than she intended.

The 38-year-old recovered quickly, but not quickly enough, with photographers snapping pics of the brunette beauty sans underwear.

The revealing photos have since been removed from news websites.

Longoria reportedly laughed off the embarrassing mishap at the time but was later seen looking unhappy on the red carpet.

Eva is no stranger to the perils of risky outfit choices; she had a wardrobe malfunction at the Golden Globes earlier this year in a black dress with a similar cut.
