LOS ANGELES, Calif. -- Christina Aguilera has grown close with fellow “The Voice” coaches Blake Shelton, Adam Levine and Cee Lo Green – but who is her closest friend on the NBC show and who would make – if they weren’t attached — the best boyfriend material?

The singing superstar stopped by Access Hollywood Live on Monday, where Billy Bush and Kit Hoover found out Christina’s take on her “Voice” boys.

“Who would be the best friend, like if you had to talk about something emotional or heavy in your life?” Billy asked.

“At this point, I’d probably go to Blake,” she said, referring to the country cutie she sits next to on “The Voice” panel.

“Who would be the best boyfriend? You have to pick,” Kit continued.

“Oh no!” the star said with a laugh “That’s like a brother or something.”

Christina might not have a pick for a fellow “The Voice” coach fake boyfriend, but she does have an idea of who might be best in the bedroom.

“Who would be the best lover? Maybe not for you, but hypothetically, who would be the best performer?” Billy asked.

“Maybe Cee Lo,” Christina explained of the judge. “He gets a little freaky, a little creative.”

Kit mentioned Christina’s “girls” which have received a little attention this season – something the singer is not afraid to embrace.

“They’re the fifth judge, didn’t you know?” she said with a smile. “I mean if you got ‘em!”

Adding, “I’m not trying to fit a mold for anybody. I have to be who I am and the girls are a part of who I am.”

Another part of Christina on “The Voice” lately has been her headline-making fascinator (the bold bedazzled disc headpiece she’s worn this season).

“I’ve never been one to shy away from trying new fashions and expressing myself, I love to experiment,” she said. “I love playing with theatrics and wearing hat pieces and fun pieces. I just have fun with it. I’m a girlie girl at heart.”

“The Voice” airs Mondays at 8/7c on NBC.
