Penelope Cruz peed in the sea while making her latest movie.

The Spanish actress was pregnant while shooting 'Pirates Of The Caribbean: On Strange Tides' with Johnny Depp and when they filmed a scene on a deserted island without a toilet, she didn't hesitate to wade into the ocean whenever nature called.

She told Entertainment Weekly magazine: "I had to keep going into the water every 15 minutes."

Johnny has previously said that working with the 36-year-old beauty - who is married to actor Javier Bardem and gave birth to their first child Leo in January - is an enjoyable experience because they always end up in fits of laughter.

He said: "It's been a long road of giggles. There's nothing bad to say. I've even tried to provoke her into some fit of anger, it doesn't work, I get nothing. Giggles, more giggles."

The 'Tourist' actor also admitted he thinks she is a "phenomenal" mother.

He said: "She's an inconceivably phenomenal mommy, which I've witnessed firsthand, and it's pretty incredible. She's as loyal and true a friend as anyone could ever dream of and I'm very privileged to be able to have her in my life."
