Michelle Williams Growing Hair Long Again

When Michelle Williams visited the set of " Good Morning America" recently, she was sporting a new, longer layered cut.

After wearing her hair short for the last several years, it seems she is growing it long again.

"I think I'm ready," the 32-year-old actress told E! Online this past weekend. "It's on its way, slowly but surely."

"That's why I've stayed with short hair for so long," Williams added. "The mid-stage is insufferable. It's really hard on your self-esteem."

Williams wore a flowing blond wig for her latest role as Glinda the Good Witch, in the upcoming Disney film "Oz the Great and Powerful."

"When I first read the script, I really responded to the fact that it had a good heart at its center. Its sense of humor wasn't sarcastic or mean and I thought it was really something that my daughter could see and her friends would enjoy," the mother of 7-year-old Matilda said Tuesday on "GMA."

Now, with a few months off between roles, the Oscar nominated actress has time to dedicate to her hair.

"I'm really happy to not have anything looming - except my hair," Williams joked. "I'm really working on my hair growing out."
