Gwen Stefani Dishes on Her Outrageous Hair Styles: 'Everything Is Fake'

Gwen Stefani is notorious for changing up her 'dos.
The 45-year-old singer has rocked just about every hairstyle, and she happily spilled a dirty little hair secret to ET.
"Nothing here is me. Everything is fake," Stefani told ET at a BeautyCon-hosted tea party in Los Angeles last Friday where she was promoting her new Harajuku fragrance collection and accessories.
In taking a look at her "fake" hair, she certainly manages to pull off the classic high pony and even the high double-bun updo.

And even when her hair is down, she's still able to rock a bun on her head.

Stefani is also no stranger to mixing up her color.
Her most recent look has some black accents to her signature 'blonde locks.

And she even made a video montage when she went bubble-gum pink.

But who can forget how she started the blue hue trend back in 1998?

With all of these fun hairstyles and colors, you may just be wondering what Stefani's real hair actually looks like.
"Um, who knows? I haven't seen it since ninth grade," Stefani admitted.
While you may not ever see her real hair, you can see Stefani on The Voice again this fall.
"I think I have a great team," she teased. "When you start to get to know them and get in the room with them and work with them, you really start to really understand what you got. The talent you got. It's super incredible."
