Gwyneth Paltrow admits she is "a little bit borderline" obsessive about germs.

The 38-year-old actress stars in new epidemic thriller 'Contagion' as a woman who contracts a deadly disease, and she admits the storyline had a worsening effect on her fear of nasty microbes.

When asked if starring in the film gave her Obsessive Compulsive Disorder (OCD) on UK TV show 'Lorraine', Gwyneth replied: "There was actually a New York Observer article - they sent a microbiologist out in New York City to swab surfaces, like a clean glass in a Five Star restaurant, The Subway, handles, and it was so disturbing what they found, and since that article I've been a hand washer.

"So this movie didn't make me any worse, but it was already a little bit borderline."

The health conscious star - who runs the website Goop about healthy and ethical eating - has previously revealed she uses a handset which she plugs into her cell phone in order to minimise "radiation".

Gwyneth - who raises two children, Apple, seven, and five-year-old Moses, with her husband, Coldplay singer Chris Martin - said: "A handset cuts down on cell phone radiation. I use the YUBZ Retro Handset for my BlackBerry calls."
