Just in time for the new year, Rachel McAdams is debuting a new look!

The 'Mean Girls' star was spotted in LAX this week all bundled up and rocking her stylish new ombre hair.

Okay, so she could dye her hair green and still look amazing. Needless to say, Regina George is KILLING this look.

We've seen the actress, who's a natural brunette, in plenty of different hair colors including shades of blonde, brown and red, but this is the first time the 36-year-old has sported the trendy ombre hair.

Looking good, girlfriend.
