ET met up with Shailene Woodley at Vanity Fair's 20th anniversary of "Vanities" and discovered the important impact that Descendants co-star George Clooney has had upon her life.
"He has taught me how to be a better human being on [many] different levels," the 20-year-old actress asserted. "Just from a human perspective he really has taught me to enlargen myself and to be a more compassionate, humble human being."
The event—which was put on by Vanity Fair, Juicy Couture, and V.F.'s West Coast Editor Krista Smith—was hosted in support of All It Takes, a charity that Woodley and her mother recently founded.
Also in attendance at the event were past "Vanities" Hayden Panettiere, Malin Akerman, Jessica Chastain, as well as Olivia Munn, who will grace the cover of Vanity Fair.
