Avril Lavigne is a big fan of the color pink. Pink clothes in her fashion line, pink on her signature fragrance, pink streaks in her hair.

And pink on her head.

Lavigne and a friend were out partying on the Sunset Strip on Monday night, and Avril made a statement with a pink stocking cap.

Avril seemed a little more reserved last night than she did the last time she was caught partying by the paparazzi cameras.

Perhaps that pink hat is her thinking cap?
