Speaking to Extra, Aguilera said she is anxious to see new coaches Usher and Shakira interact with veterans Adam Levine and Blake Shelton.

"I'm here because it's a family environment, and I'm here in support of any woman who is willing to take on these boys," Aguilera declared.

Aguilera wished Shakira luck on The Voice, saying: "It's a lot of testosterone, but I know [new coach] Shakira will handle it."
