Katherine Heigl & Cameron Diaz's Copycat Hairstyles Have Us Seeing Double!

See the stars rock almost identical hairstyles all week long!

Have Katherine Heigl and Cameron Diaz been calling in to the same red carpet hairstyle hotline? That's what these matching 'dos might have you believe.

The gorgeous blondes have been rocking almost identical styles these past two weeks—from cropped curls and sleek bobs to elegant updos.

Heigl is making the rounds, traveling between L.A. and NYC, to promote her new movie One for the Money. Diaz stuck around just long enough for the Golden Globes before jetting off to Paris for Fashion Week.

It's a good thing they're continents apart. Being Hollywood hair twins ranks just below wearing the same dress to a party!
