The stunning star's right breast popped out of her skimpy bikini as she relaxed on the beach in Puerto Rico.

Eva, 37, spotted the wardrobe malfunction and quickly covered herself with the orange two-piece - but not before an eagle-eyed snapper captured the nip-slip on camera.

It's not the first time the Desperate Housewives star has accidentally exposed herself in public.

Just three months ago the same right boob fell out of Eva's frock as she posed on the red carpet at the Golden Globe Awards in LA.

The actress jetted to Puerto Rico over the weekend to celebrate a pal's wedding.

But she didn't waste the opportunity to top up her tan, hitting the beach between festivities so she could show off her fabulous bikini body during sunbathing sessions.

It's hard to believe but Eva's currently on the market after splitting up with ex-boyfriend Eduardo Cruz (Penelope's brother).

She recently hinted she's considering hitting the internet to find a new man, revealing one of her best friends got hitched to a fella she met online.

Eva said: "My girlfriend went on Match.com, and she's getting married this year. They're perfectly matched for each other; they're really a great couple.”
