Jessica Alba is known as one of the sexiest actresses out there, but you won’t ever catch her nude on the big screen.

Alba revealed why exactly she won’t ever film a nude scene, during an interview with Glamour for its June issue.
“I don’t want my grandparents to see my boobs. That’s it,” she said.

“It would be weird at Christmas. And, I mean, really, if you look at the movies I have done, getting naked would never ‘elevate’ the picture,” she went on to say.

According to E! News, the 33-year-old actress even has a nudity clause that explicitly states she will not be appearing nude on camera.

The starlet also spoke out on her belief in feminism and the fact that females should be independent and never have to rely on a man.

“She taught me how to hustle. I was determined to be financially independent,” Alba said, referring to her mom. “So I started making my own money when I was 12 [with acting]. That was freedom."

Catch Alba in Sin City: A Dame to Kill For, which hits theaters on Aug. 22.
