"Avatar" actress Zoe Saldana has revealed that she has almost 10 secret tattoos on her body that remain covered most of the time.

Saldana stopped by David Letterman's "Late Show" recently to promote her new film "Guardians of the Galaxy" and spoke of her husband Marco Perego, who recently had her portrait tattooed onto his forearm. She also shared that he has more body art than she does, reported contactmusic.com.

"I'm running out of private places to put them on. My husband has more, his are more exposed," Saldana said.

Her newest addition is the word "Heal", written in Hebrew, under her right breast.
