Avril Lavigne airport luggage suitcase Hello Kitty hoodie green hair phone bodyguard

Apparently Avril didn't get the memo -- Halloween's in October, not in April!

Kidding ... we're used to the singer adding stripes of color to her hair but there's just something about green, paired with a black hoodie, that gives the Sk8r girl a goolish vibe.

Avril rolled solo yesterday as she returned on the same flight as Miley from Chicago. Avril taped The Oprah Winfrey Show set to air this Wednesday along with Stevie Nicks and others. Can't wait!
