It was an unfortunate moment last week for Heidi Klum when she accidentally had a nip slip moment in Hawaii. This time, Eva Longoria falls victim to another nip flash.

Celebrities should be mindful that they are being followed 24/7 by paparazzi who are taking shots of their every move. It was an unfortunate case for Eva Longoria when she experienced a bikini malfunction while trying to get a tan at the beach.

The Desperate Housewives star revealed more than what she should when her bikini top dropped exposing her nipples. Of course wardrobe malfunctions are common for these Hollywood stars, but the embarrassment and the attention after might be too much before everything simmers down again.

But Eva seems oblivious of her surroundings as she soaked up under the sun during her short trip to Puerto Rico. The actress was photographed swimming at the sea, strolling around the white sand beach and relaxing on a sun lounger.

Eva was alone during her recent trip. Perhaps it's the reason why her face looked a bit glum. The actress hasn't had much luck in the love department ever since she spilt from her recent boyfriend last year in October. She split from New York Jets star Mark Sanchez after just two months of dating.

"Mark adores and respects Eva. It really was about scheduling more than anything else. They will remain close friends," Mark's representative released in a statement.

It looks like Eva is having a difficult time getting another relationship after her failed marriage to NBA star Tony Parker. The once lovey dovey pair called it quits after the actress allegedly found hundreds of text messages to another woman on her ex-husband's phone.
