Reese Witherspoon and Jennifer Aniston celebrated the power of women last night at Elle’s annual Women in Hollywood celebration in Beverly Hills, as Witherspoon presented her longtime friend with one of the night’s honors. When Aniston took the stage to accept her award, she used her moment to declare what she loved most about women—the power to inspire. “So many amazing women have come before me, and all of us, who have inspired me to reach the heights that I’ve wanted to reach and keep going,” she said. “We have to continue inspiring and supporting and loving and encouraging each other for all of the young women following in our footsteps.” Inspired by her acceptance speech, InStyle.com caught up with Naomi Watts, Rachel Zoe, Katherine Heigl, and more celebrities to find out what they loved about being a woman.
