Washington, November 5 Actress Natalie Portman has revealed that she is open to the idea of cosmetic surgery to maintain her youthful looks.

The 28-year-old Israeli American star said she was aware of Hollywood's ageist attitude and feared being dropped for younger talent as she wrinkles.

"You see people who were stars five years ago and already they're waning," Contactmusic quoted her as telling America's V magazine.

"As actresses approach 40, it starts becoming really, really difficult," she added. (ANI)
