Zoe Saldana claims she is a "bad influence" on her sisters, Mariel and Cisley.

The 36-year-old actress, who is reportedly expecting twins with husband Marco Perego, admits she has "almost 10" hidden tattoos on her body and is also responsible for many of her family members' inkings.

She said: "I am very proud to say I have assisted many friends and family, my sisters, to get tattoos. I get them drunk, I wine and dine them, I take them to the tattoo parlor, they come out with tattoos. The next day they're like, 'What the hell happened?!'

"I can convince you of getting a tattoo in the worst place possible. I am very convincing. That's why I've always been sort of the bad influence out of all the girls in my family."

Despite having no visible tattoos, the 'Guardians of the Galaxy' star also told David Letterman on his late night chat show that her love of body art might not be a secret for much longer.

She said: "I'm running out of private places to put them on.

"My grandmother says that I look like a newspaper naked."

Shortly after she married Marco last year, he unveiled a portrait of her face on his forearm, but he also has an impressive collection of body art.

She said: "My husband has more. His are more exposed."
