Well, Avril Lavigne knows how to stick to a theme. The Canadian pop tart was rocking a truly bizarre lime green getup in London this week as she made her way to the Soho Hotel. Avril had matched her hair to her bag and her tank top...how novel!

Lavigne courted controversy recently after she dropped the F-word during a performance at a Tampa Rays baseball game. The singer apologized for her foul mouth soon thereafter.
