Katherine Heigl Debuts A Darker 'Do

Katherine Heigl rocks much darker hair as she walks to a nail salon with her sister, Meg, after getting some lunch on Monday (March 8) in Los Feliz, Calif.

The 31-year-old actress helped Meg carry her daughter – Kat became an aunt shortly before baby Naleigh‘s adoption was approved!

Doesn’t Kat resemble Katharine McPhee with her darker hair?
