Julia Roberts Lisa Roberts Gillan red carpet Tribeca coat black sisters

Julia Roberts left her husband and three kids at home to attend the premiere of her new film as producer, Jesus Henry Christ at the Tribeca Film Festival over the weekend with sister and co-producer, Lisa Roberts Gillan.

Julia went back to blonde for the film's debut, where she revealed that it was Lisa who really did all the work!

"She really does the heavy lifting," Roberts told Extra, "and I just put on the eyeliner and show up at the end!"

Julia also dished on good friend Oprah Winfrey's big finale. See what she had to say ... after the jump!
