The actress has now opened up about her first piece of body art during an appearance on The Late Show With David Letterman, insisting the butterfly comes from a story her mother told her.

She says, "A butterfly landed on my mom's stomach a week before I was born and that's how I got my name, because Vanessa means butterfly - it's a Latin derivative."

She adds, "It's my very first tattoo. I kind of feel like a bada** now."
