Scarlett Johansson touches upon her bad habit, says, ‘I'm so ashamed’

Scarlett Johansson recently shared her nasty habit that she never wants her children to know about it.

The Black Widow star revealed a personal detail about herself on Wednesday's edition of The Drew Barrymore Show and left her fans in shock.

During the interview, the 37-year-old actor spilled that she feels ashamed to have started smoking as a youngster.

"My daughter may have asked me this before," the Lucy star admitted as per Daily Mail. "I used to smoke when I was younger and I'm so ashamed. I just don't want her to ever think that I ever thought it was cool 'cause she can never, ever, ever smoke." She added: "So yeah, I just hope she never figures that out."

The five-time Golden Globe winner went on to say, "When parents 'forbid' their children from doing certain things, their children don't do them."
