Top 20 best celebrity Halloween costumes of 2015 – You need to see #1! (With Pictures)

11. Gwen Stefani

Gwen Stefani is one of the most acclaimed artists to ever hit a recording studio and is the winner of several awards. On top of that she can record some incredibly catchy tunes. If you don’t believe me, just listen to “Hollaback Girl” and try and not get that stuck in your head. Gwen’s recently all over the tabloids due to her new relationship with country superstar Blake Shelton. Perhaps Gwen was trying to show Blake that she can support his country roots, when she donned a sexy cowgirl outfit this past Halloween. Now, I’m not digging the boots or the yellow tights, but I suppose Blake is a fan and I guess that’s the only person that matters!
