There's not a drop of America's Sweetheart in Julia Robert's portrayal of Mirror Mirror's Evil Queen Clementianna.

But the mom to 7-year-old twins Hazel and Phinnaeus and 4-year-old Henry doesn't know if she's ready to let her three kids with hubby Danny Moder, 43, see their mom in such a villainous role.

"I think my kids are too young to see the movie, considering my part," Roberts tells Us Weekly of playing Snow White's tormentor.

It's a rare return to the screen for the actress, who stars opposite Lily Collins in the Snow White remake.

"It was a lot of fun," the 44-year-old tells Us of her role. "I could go off the rails in any direction at any time.

As for any signs of the Evil Queen coming out at home?

"I am happy to announce that [the Evil Queen] is not inside me!" she laughs. "But without naming names, I drew [how to play the part] from a couple of people I know."
